    SUMMARY *
    Environmental Law
    The panel affirmed in part, and reversed in part, the
    district court’s judgment in favor of federal agencies in an
    action brought by plaintiff environmental groups
    challenging the decision of the National Marine Fisheries
    Service (“NMFS”) to allow a Hawaii-based swordfish
    fishery to increase its fishing efforts, which may result in the
    unintentional deaths of endangered sea turtles; and
    challenging the decision of the U.S. Fish and Wildlife
    Service (“FWS”) to issue a “special purpose” permit to the
    NMFS, which authorized the fishery to incidentally kill
    migratory birds.
    The panel held that the FWS’s decision to issue a special
    purpose permit to the NFMS on behalf of a commercial
    fishery was arbitrary and capricious. The panel held that the
    FWS’s interpretation of 50 C.F.R. § 21.27 as authorizing it
    to grant an incidental take permit to the NMFS did not
    conform to either the Migratory Bird Treaty Act’s

    conservation intent or the plain language of the regulation.
    The panel therefore reversed the district court’s grant of
    summary judgment affirming the FWS’s decision to issue
    the permit.
    The panel held that NMFS’s 2012 Biological Opinion’s
    “no jeopardy” finding as to the loggerhead sea turtles was
    arbitrary and capricious because the scientific data suggested
    that the loggerhead population would significantly decline,
    and the agency failed to sufficiently explain the discrepancy
    in its opinion and record evidence. Specifically, the panel
    held that the climate-based model predicted that the
    proposed action would exacerbate the loggerheads’ decline,
    and the Biological Opinion was structurally flawed to the
    extent the NMFS failed to incorporate those findings into its
    jeopardy analysis. The panel therefore reversed the district
    court’s grant of summary judgment upholding this portion of
    the Biological Opinion.
    The panel otherwise affirmed the district court’s grant of
    summary judgment to defendants, and remanded. The panel
    held that the NMFS’s no jeopardy conclusion regarding the
    leatherback turtles found support in the scientific record, and
    therefore was sufficient to withstand judicial review.
    Specifically, the panel held that it could not conclude that the
    2012 Biological Opinion violated the Endangered Species
    Act or that the NMFS otherwise acted arbitrarily and
    capriciously in determining that the fishery would have no
    appreciable effect on the leatherback turtle population. The
    panel also held that the NMFS’s consideration of climate
    change in the Biological Opinion was neither arbitrary,
    capricious, nor contrary to the NMFS’s obligation to base its
    jeopardy decision on the best scientific data it could obtain.
    Judge Callahan dissented in part. Judge Callahan agreed
    with the majority that the 2012 Biological Opinion was not
    4 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    arbitrary and capricious in determining that the Hawaii-
    based shallow-set fishery expansion would have no
    appreciable effect on the leatherback sea turtle population,
    and that the 2012 Biological Opinion adequately considered
    the impact of global climate change; and dissented from the
    remainder of the majority opinion. Judge Callahan would
    uphold the Migratory Bird Treaty Act Permit and the
    loggerhead sea turtle Biological Opinion.

    TURTLE ISLAND RESTORATION NETWORK V. USDOC 5
    OPINION
    MURGUIA, Circuit Judge:
    Plaintiffs Turtle Island Restoration Network and the
    Center for Biological Diversity challenge the decision of the
    National Marine Fisheries Service (“NMFS”) to allow a
    Hawaii-based swordfish fishery to increase its fishing
    efforts, which may result in the unintentional deaths of
    endangered sea turtles. Plaintiffs also challenge the decision
    of the U.S. Fish and Wildlife Service (“FWS”) to issue a
    “special purpose” permit to the NMFS, which authorizes the
    fishery to incidentally kill migratory birds.
    Plaintiffs brought suit against the agencies under various
    environmental statutes that the NMFS and the FWS are
    charged with administering, including the Magnuson-
    Stevens Fishery Conservation and Management Act (the
    “Magnuson-Stevens Act”), the Endangered Species Act of
    1973 (“ESA”), the Migratory Bird Treaty Act (“MBTA”),
    and the National Environmental Policy Act (“NEPA”). The
    Hawaii Longline Association subsequently intervened to
    represent the interests of the swordfish fishery in defense of
    the agencies’ actions. We have jurisdiction under 28 U.S.C.
    § 1291, and we affirm in part, and reverse and remand in
    part.
    BACKGROUND
    I. Regulatory Framework
    In response to concerns about overfishing, Congress
    enacted the Magnuson-Stevens Act to promote the long-term
    biological and economic sustainability of marine fisheries in
    U.S. federal waters. See 16 U.S.C. § 1801(b). Under this Act,
    the NMFS and eight regional councils develop
    6 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    “management plans” for the nation’s fisheries, which the
    Secretary of Commerce may approve, partially approve, or
    reject. 
    Id. §§ 1801(b)(4),
    1852(h)(1), 1854(a)(3). The
    Magnuson-Stevens Act demands that a management plan be
    consistent with the national standards set out in the Act and
    “any other applicable law,” 
    id. § 1853(a)(1)(C),
    including
    the ESA, 
    id. §§ 1531–43,
    and the MBTA, 
    id. §§ 703–12.
    The ESA provides for the conservation of fish, wildlife,
    and plant species that are at risk of extinction by requiring
    federal agencies to ensure that actions they authorize, fund,
    or carry out are “not likely to jeopardize the continued
    existence” of any ESA-listed species. 16 U.S.C.
    § 1536(a)(2). Agencies proposing actions that may affect an
    ESA-listed species must consult with either the NMFS or the
    FWS—depending on the species involved—which then
    reviews the proposed action and prepares a “biological
    opinion” (“BiOp”) that evaluates whether and the extent to
    which the action may impact the species. 
    Id. § 1536(b);
    50 C.F.R. § 402.12. If the NMFS or the FWS finds that the
    proposed action would not jeopardize any species’ continued
    existence, it issues a statement permitting the “taking” of a
    particular number of protected animals “if such taking is
    incidental to, and not the purpose of, the carrying out of an
    otherwise lawful activity.” 16 U.S.C. § 1539(a)(1)(B).
    The FWS also has authority to enforce the MBTA, 
    id. §§ 703–12;
    50 C.F.R. § 10.1, which strictly prohibits the
    taking of any migratory bird the Act protects except under
    the terms of a valid permit issued by the Secretary of the
    Interior, 
    id. § 703(a).
    The Secretary of the Interior has issued
    regulations authorizing various types of exemptions to the
    MBTA permitting the taking of migratory birds under
    certain circumstances. See 16 U.S.C. § 704(a).
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 7
    In addition to the substantive mandates of the ESA and
    the MBTA, both the NMFS and the FWS are subject to
    NEPA’s procedural requirements. See Robertson v. Methow
    Valley Citizens Council, 
    490 U.S. 332
    , 348 (1989). NEPA is
    concerned with process alone and “merely prohibits
    uninformed—rather than unwise—agency action.” 
    Id. at 351.
    NEPA requires federal agencies to prepare
    environmental impact statements (“EIS”) detailing the
    effects of any proposed action that stands to have a
    significant impact on the environment. See 42 U.S.C.
    § 4332(C); 
    Robertson, 490 U.S. at 350
    . An agency may also
    prepare an environmental assessment (“EA”) to determine
    whether an EIS is needed. 40 C.F.R. §§ 1501.4(b),
    1508.9(a)(1); Te-Moak Tribe of W. Shoshone of Nev. v. U.S.
    Dep’t of Interior, 
    608 F.3d 592
    , 599 (9th Cir. 2010). If the
    EA shows that the proposed action may significantly affect
    the environment, then the agency must prepare a full EIS. W.
    Watersheds Project v. Abbey, 
    719 F.3d 1035
    , 1050 (9th Cir.
    2013). Otherwise, the agency issues a finding of no
    significant impact and the proposed action can proceed
    without further study. 
    Id. II. The
    Hawaii-Based Longline Fishing Industry
    “Longline” fishing is a commercial fishing method that
    involves reeling out—or “setting”—a single, horizontal
    mainline to which shorter “branchlines” are attached at
    intervals. Each dangling branchline carries baited hooks. A
    typical longline set can use several hundred or thousand
    individual hooks, allowing a single fishing vessel to spread
    its efforts over a large area. While the mainline is in the
    water, the fishing equipment often ensnares birds, sea turtles,
    and other marine wildlife in addition to the target fish. This
    incidental taking of non-target animals is known as
    “bycatch.”
    8 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    The NMFS collects bycatch statistics by tracking the
    number of times a non-target animal is hooked or entangled
    by fishing gear. The most commonly observed non-target
    animal interactions are with Northern Pacific loggerhead and
    leatherback sea turtles, both of which are currently listed
    under the ESA as “endangered.” See 50 C.F.R. § 17.11. In
    addition, several types of albatross interact often with the
    longline fisheries, including the black-footed albatross and
    the Laysan albatross.
    There are two separately regulated longline fisheries
    based out of Hawaii: the deep-set fishery—which targets
    tuna—and the shallow-set fishery, which targets swordfish.
    The two fisheries are managed by the Fishery Ecosystem
    Plan for Pelagic Fisheries of the Western Pacific Region
    (“Pelagics FMP”), developed by the Western Pacific Fishery
    Management Council (“Council”) in accordance with the
    Magnuson-Stevens Act and implemented by the NMFS. In
    2001, the shallow-set fishery was closed by court order due
    to the NMFS’s failure to prepare an EIS analyzing the impact
    of longline fishing on the sea turtle population, which the
    court found was a violation of the agency’s NEPA
    obligations. See Leatherback Sea Turtle v. Nat’l Marine
    Fisheries Serv., No. 99-00152, 
    1999 WL 33594329
    (D.
    Haw. Oct. 18, 1999). In response, the NMFS issued an EIS
    and a BiOp in which the agency concluded that the shallow-
    set fishery was adversely affecting several species of sea
    turtles. In 2002, the NMFS issued regulations prohibiting all
    Hawaii-based swordfish longlining.
    The Council subsequently developed various measures
    to minimize turtle bycatch, and in 2004 the NMFS
    reauthorized shallow-set longlining subject to new
    restrictions designed to reduce the number and severity of
    interactions between protected turtles and fishing gear. In
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 9
    part, the NMFS strictly limited the number of interactions
    the fishery could have with leatherback and loggerhead sea
    turtles to a maximum of 16 and 17, respectively, per fishing
    season. Further, the NMFS imposed an annual limit of 2,120
    shallow sets, which represents fifty percent of the average
    number of sets deployed prior to the fishery’s closure in
    2001.
    In 2008, the NMFS proposed an amendment to the
    Pelagics FMP (“Amendment 18”) that would remove the
    2,120 annual set limit, allowing gear deployments to
    increase to their pre-2001 maximums, and also increase the
    number of sea turtle interactions allowed each year. After
    consulting internally pursuant to the ESA, the NMFS
    produced a BiOp concluding that Amendment 18 would not
    jeopardize the sea turtles. The NMFS issued a final rule
    implementing Amendment 18 in December 2009. 74 Fed.
    Reg. 65,640 (Dec. 10, 2009).
    Plaintiffs initiated suit against the NMFS on the grounds
    that the 2009 rule violated the ESA and the MBTA. See
    Turtle Island Restoration Network v. U.S. Dep’t of
    Commerce, 
    834 F. Supp. 2d 1004
    , 1007 (D. Haw. 2011).
    Plaintiffs’ MBTA claim was based on the fishery’s
    incidental take of migratory seabirds without an MBTA
    permit. The parties settled the case, and the NMFS entered
    into a consent decree that required it to withdraw its no
    jeopardy BiOp, reinstate the 2004 annual turtle-interaction
    caps, and issue a new BiOp after deciding whether to
    reclassify various population segments of sea turtles under
    the ESA. 
    Id. at 1023–25.
    The other remaining provisions of
    the 2009 rule remained in effect, including the removal of
    annual set limits.
    The NMFS later proposed raising the shallow-set
    fishery’s annual turtle interaction cap to 26 (with
    10 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    leatherbacks), and 34 (with loggerheads) and otherwise
    continuing to operate the fishery in accordance with the
    provisions of Amendment 18 to the Pelagics FMP. In
    January 2012, the NMFS issued a new BiOp concluding that
    the shallow-set fishery would not jeopardize the continued
    existence of either the loggerhead or leatherback turtles if it
    operated under higher caps on turtle interactions.
    While it was engaged in the re-consultation process, the
    NMFS submitted an application to the FWS for a special
    purpose permit that would allow the shallow-set fishery to
    take migratory seabirds in connection with swordfish
    longlining. The FWS issued a final EA in which it
    considered denying the permit, granting the permit as
    requested, and granting the permit while requiring the
    NMFS to conduct new research on additional ways to avoid
    seabird interactions. See 77 Fed. Reg. 1501 (Jan. 10, 2012).
    The FWS ultimately concluded that none of the alternatives
    would have a significant adverse impact on the seabirds’
    population levels. Accordingly, the FWS issued a finding of
    “no significant impact.” In August 2012, the FWS granted a
    three-year special purpose permit authorizing the shallow-
    set fishery to kill a maximum of 191 black-footed albatross,
    430 Laysan albatross, 30 northern fulmars, 30 sooty
    shearwaters, and one short-tailed albatross. Of those birds,
    only the short-tailed albatross is listed under the ESA,
    50 C.F.R. § 17.11(h).
    Plaintiffs subsequently filed this lawsuit under the ESA,
    the MBTA, and their implementing regulations, challenging
    the NMFS’s final rule approving the continued operation of
    the shallow-set fishery and the FWS’s issuance of a
    migratory bird permit to the NMFS. After the parties moved
    for summary judgment, the district court ruled in the
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 11
    agencies’ favor on all of Plaintiffs’ claims. Plaintiffs timely
    appealed.
    STANDARD OF REVIEW
    We review challenges to final agency action decided on
    summary judgment de novo and pursuant to Section 706 of
    the Administrative Procedure Act (“APA”). Turtle Island
    Restoration Network v. Nat’l Marine Fisheries Serv.,
    
    340 F.3d 969
    , 973 (9th Cir. 2003). Review is based on the
    administrative record. Camp v. Pitts, 
    411 U.S. 138
    , 142
    (1973).
    The APA requires courts to “hold unlawful and set aside
    agency action, findings, and conclusions found to be . . .
    arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law,” “in excess of statutory
    jurisdiction,” or “without observance of procedure required
    by law.” 5 U.S.C. § 706(2)(A), (C)–(D). “The scope of
    review under the ‘arbitrary and capricious’ standard is
    narrow and a court is not to substitute its judgment for that
    of the agency.” Motor Vehicle Mfrs. Ass’n of U.S., Inc. v.
    State Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983).
    Nevertheless, we require the agency to “examine the
    relevant data and articulate a satisfactory explanation for its
    action,” and we will strike down agency action as “arbitrary
    and capricious if the agency has relied on factors which
    Congress has not intended it to consider, entirely failed to
    consider an important aspect of the problem, offered an
    explanation for its decision that runs counter to the evidence
    before the agency,” or if the agency’s decision “is so
    implausible that it could not be ascribed to a difference in
    view or the product of agency expertise.” 
    Id. Separate from
    the APA, we also give deference to an
    agency’s interpretation of the statutes and regulations that
    12 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    define the scope of its authority. Chevron, U.S.A., Inc. v.
    Natural Resources Defense Council, Inc. compels us to defer
    to an agency’s reasonable interpretation of its enabling
    legislation. 
    467 U.S. 837
    , 843 (1984). Under the Chevron
    analysis, we must first exhaust the traditional tools of
    statutory construction to determine whether Congress has
    “directly spoken to the precise question at issue.” 
    Id. at 842.
    If we determine that the statute is silent or ambiguous on the
    question at hand, then at Chevron step two we must respect
    the agency’s interpretation so long as it “is based on a
    permissible construction of the statute.” 
    Id. at 843.
    A
    permissible construction is one that is not “arbitrary,
    capricious, or manifestly contrary to the statute.” 
    Id. at 844;
    see also Judulang v. Holder, 
    132 S. Ct. 476
    , 483 n.7 (2011)
    (recognizing that Chevron step two is equivalent to the
    APA’s arbitrary and capricious standard).
    Chevron deference applies only to agency decisions
    rendered through formal procedures. United States v. Mead
    Corp., 
    533 U.S. 218
    , 226–27 (2001). However, under Auer
    v. Robbins, we must also defer to an agency’s interpretation
    of its own ambiguous regulations, which controls unless
    “plainly erroneous or inconsistent with the regulation,” or
    where there are grounds to believe that the interpretation
    “does not reflect the agency’s fair and considered judgment
    of the matter in question.” Christopher v. SmithKline
    Beecham Corp., 
    132 S. Ct. 2156
    , 2159 (2012) (quoting Auer
    v. Robbins, 
    519 U.S. 452
    , 461–62 (1997)). Similarly, “we
    must ensure that the interpretation is not inconsistent with a
    congressional directive; a court need not accept an agency’s
    interpretation of its own regulations if that interpretation is
    inconsistent with the statute under which the regulations
    were promulgated.” Marsh v. J. Alexander’s LLC, 
    869 F.3d 1108
    , 1116–17 (9th Cir. 2017) (internal changes, quotation
    marks and citations omitted). Our review of an agency’s
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 13
    construction of a statute or regulation that does not qualify
    for either Chevron or Auer deference is de novo, although
    we may still accord the agency’s opinion some weight.
    Satterfield v. Simon & Schuster, Inc., 
    569 F.3d 946
    , 952–53
    (9th Cir. 2009) (citing Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140 (1944)).
    DISCUSSION
    I. “Special Purpose” Permit
    Plaintiffs argue that the FWS acted arbitrarily and
    capriciously by issuing a special purpose permit to the
    NMFS on behalf of a commercial operation—the shallow-
    set fishery—that provides no benefit to migratory birds.
    Plaintiffs specifically contend that, in issuing this permit, the
    FWS ignored or violated its obligations under the MBTA.
    The MBTA is a strict liability criminal statute that
    Congress enacted for the “object and purpose . . . to aid in
    the restoration of [game and other wild] birds.” 16 U.S.C.
    § 701. The MBTA states in expansive language that, unless
    otherwise permitted by the Secretary of the Interior, “it shall
    be unlawful at any time, by any means or in any manner, to
    pursue, hunt, take, capture, kill, [or] attempt to take, capture,
    or kill . . . any migratory bird.” 16 U.S.C. § 703(a). The
    MBTA also limits the FWS’s authority to authorize the
    killing of migratory birds absent specified regulations
    “[s]ubject to the provisions and in order to carry out the
    purposes of the conventions” underlying the Act. 
    Id. § 704(a).
    The conventions underlying the MBTA stipulate
    that migratory birds may only be killed under “extraordinary
    conditions,” where birds have “become seriously injurious
    to the agricultural or other interests in any particular
    community.” Humane Soc’y of the U.S. v. Glickman,
    14 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    
    217 F.3d 882
    , 885 (D.C. Cir. 2000) (internal quotation marks
    omitted).
    Pursuant to the MBTA, the FWS has enacted a
    permitting program for narrow categories of migratory bird
    takings, such as scientific collecting, rehabilitation, hunting,
    and depredation control. See 16 U.S.C. §§ 704(a), 712(2)
    (empowering the FWS to promulgate implementing
    regulations); 50 C.F.R. §§ 21.21–21.61 (authorizing the
    issuance of various types of permits). The FWS has also
    established a “special purpose” permit that allows a person
    to “lawfully take . . . migratory birds . . . for any purpose not
    covered by the standard form permits” included elsewhere
    in the regulations. 50 C.F.R. § 21.27(a). The FWS may issue
    such a permit for “special purpose activities related to
    migratory birds,” where the applicant “makes a sufficient
    showing” that the activity would be “of benefit to the
    migratory bird resource, important research reasons, reasons
    of human concern for individual birds, or other compelling
    justification.” 
    Id. Here, the
    FWS interpreted § 21.27 as authorizing it to
    grant a special purpose permit sanctioning the incidental take
    of migratory birds to the NMFS, thereby allowing a
    commercial activity—longline fishing—that does not
    concern bird conservation. In its decision to issue the permit,
    the FWS found that the “commercial fishery carries no
    intrinsic benefit for migratory bird resources,” “the take that
    occurs is neither directed by, nor is the result of, important
    research,” and that “the take that occurs does not result from
    concern for individual birds.” However, the FWS found that
    “compelling justification” existed to permit the continued
    operation of the shallow-set fishery, which the FWS
    believed “provides a net benefit to the Nation” economically
    and “serves as a benchmark internationally for employing
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 15
    effective seabird mitigation techniques and serves as an
    example of responsible conservation practices by a fishery.”
    The FWS also noted that “[c]losure of this fishery would
    likely result in replaced effort by foreign longline fleets to
    supply swordfish demand, where use of bycatch mitigation
    methods would not likely follow international best
    practices.”
    We conclude that the FWS’s decision to issue a special
    purpose permit to the NMFS on behalf of a commercial
    fishery was arbitrary and capricious. Although the FWS’s
    interpretation of § 21.27 would ordinarily deserve deference,
    see 
    Mead, 533 U.S. at 226
    –27, we cannot conclude that such
    deference is appropriate in this case. Deference to the FWS’s
    interpretation is not warranted because the plain language of
    this regulation is not reasonably susceptible to the FWS’s
    new interpretation. The other “standard form permits” the
    MBTA regulations authorize govern discrete types of
    takings, such as scientific collecting, taxidermy, and
    rehabilitation, and although § 21.27 is intended to allow the
    FWS to authorize activities not otherwise permitted by the
    regulations, it is still a narrow exception to the MBTA’s
    general prohibition on killing migratory birds. See 
    Marsh, 869 F.3d at 1116
    –17 (“[W]e must always ensure that the
    interpretation is not inconsistent with a congressional
    directive . . . .”); Ctr. for Biological Diversity v. Salazar,
    
    706 F.3d 1085
    , 1092 (9th Cir. 2013) (“[W]e must interpret
    [a] regulation as a whole, in light of the overall statutory and
    regulatory scheme . . . .” (internal quotation marks
    omitted)). The FWS’s construction of § 21.27’s “special
    purpose activit[y]” exception as applying to basic
    commercial activities like fishing that have no articulable
    “special purpose” is therefore inconsistent with the existing
    permitting scheme that the FWS has enacted. The FWS must
    read the “special purpose” provision in the context of the
    16 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    regulation’s other requirements that, taken together, fail to
    turn § 21.27 into a general incidental take exception: the
    permit must “relate[] to migratory birds” and may issue only
    upon a “sufficient showing of . . . [a] compelling
    justification.” 50 C.F.R. § 21.27.
    The FWS unpersuasively argues that the phrase “related
    to migratory birds” is not a restriction on its permitting
    authority, but merely a description of what can be permitted.
    The FWS specifically maintains that longline fishing is
    “related to migratory birds” because it incidentally interacts
    with them. Although nothing in the regulation requires that
    the permitted activity directly concern migratory birds, it
    nevertheless strains reason to say that every activity that
    risks killing migratory birds “relate[s] to” those birds. See
    50 C.F.R. § 21.27. The FWS’s approach to the regulation
    renders the majority of its text superfluous. See Nat’l Ass’n
    of Home Builders v. Defs. of Wildlife, 
    551 U.S. 644
    , 669
    (2007) (cautioning against reading an agency regulation in a
    way that renders part of it redundant).
    The FWS’s interpretation of § 21.27 as authorizing it to
    grant an incidental take permit to the NMFS does not
    conform to either the MBTA’s conservation intent or the
    plain language of the regulation. We therefore conclude that
    the FWS’s grant of a special purpose permit to the NMFS
    was arbitrary and capricious. 1
    1
    Because we conclude that the FWS acted arbitrarily and capriciously
    in issuing the incidental take permit to the NMFS under § 21.27, we need
    not reach Plaintiffs’ additional argument concerning whether the FWS’s
    action also violated NEPA.
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 17
    II. 2012 “No Jeopardy” BiOp
    Plaintiffs also argue that the NMFS violated the ESA by
    failing to properly assess the shallow-set fishery’s impacts
    on endangered sea turtles. The ESA permits federal agencies
    to authorize actions that will result in the taking of
    endangered or threatened species only if the projected take
    “is not likely to jeopardize the continued existence of” any
    listed species. 16 U.S.C. § 1536(a)(2). “Jeopardize the
    continued existence of means to engage in an action that
    reasonably would be expected, directly or indirectly, to
    reduce appreciably the likelihood of both the survival and
    recovery of a listed species in the wild by reducing the
    reproduction, numbers, or distribution of that species.”
    50 C.F.R. § 402.02 (emphasis added).
    Where listed marine species are concerned, the NMFS
    prepares a BiOp evaluating the effects of the proposed action
    on the survival and recovery of the listed species. 16 U.S.C.
    § 1536(c). The agency specifically considers the proposed
    action’s direct, indirect, and cumulative effects on a listed
    species in relation to the environmental baseline, and opines
    on whether the action is likely to jeopardize the species’
    survival. 50 C.F.R. § 402.14(g)(4); see also Nat’l Wildlife
    Fed’n v. Nat’l Marine Fisheries Serv., 
    524 F.3d 917
    , 924
    (9th Cir. 2008). Where a species is already in peril, an
    agency may not take an action that will cause an “active
    change of status” for the worse. Nat’l Wildlife 
    Fed’n, 524 F.3d at 930
    .
    When formulating a BiOp, the NMFS must base its
    conclusions on evidence supported by “the best scientific
    and commercial data available.” 16 U.S.C. § 1536(a)(2);
    50 C.F.R. § 402.14(g)(8). This requirement “prohibits [an
    agency] from disregarding available scientific evidence that
    is in some way better than the evidence [it] relies on.” San
    18 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    Luis & Delta-Mendota Water Auth. v. Jewell, 
    747 F.3d 581
    ,
    602 (9th Cir. 2014) (citation and internal quotation mark
    omitted). “The determination of what constitutes the ‘best
    scientific data available’ belongs to the agency’s ‘special
    expertise’ . . . .” 
    Id. (emphasis in
    original) (citation omitted).
    In 2012, the NMFS issued a BiOp concluding that the
    removal of the annual limit of 2,120 shallow-set lines in the
    fishery might result in the incidental “take” of Northern
    Pacific loggerhead and leatherback sea turtles, but would not
    jeopardize the continued existence of either species for the
    next 25 years. To establish the environmental baseline, the
    NMFS used existing studies on loggerhead and leatherback
    interactions with all Pacific longline fisheries (domestic and
    international) from 2000 to 2009. The NMFS ultimately
    found that the Hawaii-based shallow-set fishery is currently
    responsible for killing two to three loggerheads and
    leatherbacks (each) per year. The NMFS also determined
    that the impacts associated with anthropogenic climate
    change were likely beginning to affect both sea turtle
    species, but lacked sufficient data to quantify the threat that
    climate change posed to the turtles.
    The NMFS then attempted to predict the impact that
    allowing the fishery to deploy 5,500 longline sets per year—
    the approximate maximum annual number of sets before the
    fishery was first closed out of concern for the sea turtle
    populations—would have on the loggerheads and
    leatherbacks. The NMFS ultimately projected that setting
    5,500 lines would kill no more than one adult, female
    loggerhead turtle and four adult, female leatherback turtles.
    The NMFS then employed population viability assessment
    models to forecast the risk that killing small numbers of
    adult, female sea turtles would lead to the species’
    extinction. The NMFS concluded from the results that the
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 19
    proposed action could not reasonably be expected to
    appreciably reduce the likelihood of survival of either the
    loggerhead or the leatherback turtles.
    The NMFS’s “no jeopardy” conclusion was not affected
    by the agency’s consideration of the cumulative effects of
    worsening climates. And, the NMFS’s analysis of
    “spillover” trends suggested that the proposed increase in
    Hawaii-based swordfishing would benefit sea turtles overall.
    Because domestic fisheries operate under more stringent
    conservation measures than foreign fleets that compete to
    provide swordfish to U.S. consumers, the NMFS predicted
    that increasing domestic fishery yields would displace
    foreign fishing activities in the same area that the Hawaii-
    based shallow-set fishery operates, resulting in a net
    decrease in mortalities for the affected turtle species.
    However, because the NMFS concluded that the projected
    decrease in turtle deaths from this “spillover” effect was not
    precise enough to incorporate into its population assessment
    models, the NMFS did not incorporate these benefits into its
    no jeopardy finding.
    A. Population Viability Assessment Models
    Plaintiffs argue that the 2012 BiOp’s conclusion that the
    proposed action would not appreciably impact loggerhead
    and leatherback sea turtles is unsupported by the scientific
    methods the FWS relied on. To project the impact of the
    shallow-set fishery’s operations on the sea turtle species’
    likelihood of survival, the NMFS ran a climate-based
    population forecast model and relied primarily on the results
    of this model, “along with inputs from multiple experts and
    sources, where available.” The climate-based model showed
    a significant decline in loggerhead numbers over the next
    generation even without the proposed action of removing the
    fishery’s set limits: 99.5% of the tests showed the loggerhead
    20 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    falling below the quasi-extinction threshold within 25 years.
    When the model was run incorporating the anticipated
    mortality associated with the fishery’s operations without set
    limits, the results were similar. The NMFS specifically
    found that “[v]irtually all the loggerhead climate model runs
    . . . indicat[ed] high extinction risk with high model
    confidence.” The additional loss to the loggerhead
    population from the proposed action ranged from 4 to 11%.
    As for the leatherback turtles, the climate-based model
    showed an increase in leatherback population over the next
    generation without a change in the fishery’s set limits, and
    even with the proposed action the “extinction risk
    remain[ed] in the low category,” although the results
    predicted a “measurable loss to the population” of 16 to
    30%.
    Based on the results from the model, the NMFS decided
    that it did not “believe that the small effect posed by the
    lethal takes in this fishery, when considered together with
    the environmental baseline and the cumulative effects, will
    be detectable or appreciable” and “that the additional risk to
    the [loggerhead turtles] that would result from loss of one
    adult female annually is considered negligible.” Similarly,
    the NMFS concluded “that the proposed action would have
    a negligible impact on the risk to . . . the western Pacific
    leatherback population as a whole.” Therefore, the NMFS
    opined that increasing the maximum annual number of sets
    at the fishery would not jeopardize either species.
    1. Loggerhead Turtles
    With respect to the loggerhead turtles, the NMFS
    violated the APA’s requirement that the agency articulate a
    rational connection between the population viability model
    upon which the NMFS relied and its no jeopardy conclusion.
    The BiOp acknowledged that the climate-based model
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 21
    predicted a decline in loggerhead populations to a level that
    “represents a heightened risk of extinction,” but still upheld
    a finding of “no jeopardy” on the grounds that there was
    “little to no difference in the extinction risk when the annual
    removal of one adult female loggerhead resulting from the
    proposed action is considered in the model.” We rejected
    similar logic in National Wildlife Federation, holding that
    “where baseline conditions already jeopardize a species, an
    agency may not take action that deepens the jeopardy by
    causing additional 
    harm.” 524 F.3d at 930
    (noting that listed
    species’ “slow slide into oblivion is one of the very ills the
    ESA seeks to prevent”). In National Wildlife Federation, the
    NMFS had prepared a BiOp in which it determined that
    hydropower dam operations would not jeopardize threatened
    and endangered salmon populations. 
    Id. at 925.
    NMFS,
    however, had already determined that baseline
    environmental conditions posed a risk of jeopardy to the
    species. 
    Id. Therefore, to
    reach a conclusion of “no
    jeopardy,” the agency completely excluded from the
    environmental baseline all impacts from “nondiscretionary”
    federal activities such as operations relating to irrigation,
    flood control, and power generation. We held that this
    exclusion was improper and that baseline conditions must be
    factored into the jeopardy analysis, cumulatively with the
    entirety of agency actions. The relevant inquiry is therefore
    whether the “action effects, when added to the underlying
    baseline conditions,” are such that they would cause
    jeopardy. 
    Id. at 929.
    Here, the NMFS improperly minimized the risk of
    bycatch to the loggerheads’ survival by only comparing the
    effects of the fishery against the baseline conditions that
    have already contributed to the turtles’ decline. The BiOp’s
    no jeopardy opinion is premised on the proportionally low
    risk that the shallow-set fishery poses to the loggerheads
    22 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    relative to other threats, such as international fishing and
    climate change: the NMFS specifically found that although
    “any level of take and mortality can have an adverse effect
    on the overlying population . . . the expected level of take
    from the action, including a small number of mortalities, is
    extremely small when considered together with all impacts
    considered in the Status of the Species, Baseline and
    Cumulative Effects sections, including other federally
    authorized fisheries and foreign fisheries.” As in National
    Wildlife Federation, the agency reached an arbitrary
    conclusion by only comparing the prospective harm to the
    loggerheads that is attributable to the proposed action—the
    death of a single adult, female loggerhead per year—to the
    much greater harm resulting from factors beyond the fishery.
    Based on this impermissible comparison, the agency
    concluded that the proposed action’s adverse impacts would
    not appreciably reduce the loggerheads’ likelihood of
    survival. See Nat’l Wildlife 
    Fed’n, 524 F.3d at 930
    .
    The NMFS relies heavily on the conservative nature of
    its calculations to support the difference between its
    conclusion and the climate-based model’s results. The
    NMFS asserts that it rounded up its calculation of maximum
    adult female mortality, modeled the viability of turtle
    populations using the maximum potential number of annual
    interactions opposed to the average number of interactions
    reported in previous years, and estimated the number of sea
    turtle deaths based on the assumption that the shallow-set
    fishery would immediately operate at 5,500 sets each year.
    In reality, the increase in sets is expected to be gradual over
    many years. The ESA, however, requires agencies to
    rigorously ensure their actions will not “tip [the loggerhead]
    species from a state of precarious survival into a state of
    likely extinction.” See Nat’l Wildlife 
    Fed’n, 524 F.3d at 930
    .
    The agency may not reject the “best scientific data” in favor
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 23
    of its belief that “incidental take . . . would be reduced to the
    best extent possible” and “the vast majority of the
    loggerhead sea turtle takes from the proposed action are
    expected to be non-lethal.”
    The NMFS also notes that the climate-based model used
    an assumed fraction of the current turtle population size
    (50%) as a proxy for extinction, and explains that
    “population decline below that” number “does not
    necessarily mean that” the species is “unrecoverable” or
    “functionally extinct.” But, given the agency’s endorsement
    of the climate-based model and its expert’s decision to use a
    “quasi-extinction threshold” to reflect a decline in the turtle
    population to numbers insufficient to ensure the population’s
    viability, this logic does not support the NMFS’s
    determination that the projected population declines would
    not appreciably threaten the loggerheads’ survival.
    Another rationale presented in the BiOp is that “spillover
    effect is reasonably certain to contribute to a reduction in
    loggerhead mortalities . . . due to reduced effort in foreign
    fisheries.” Shortly thereafter, however, the NMFS noted that
    data on foreign fishery bycatch are “likely incomplete or
    inaccurate.” The NMFS went on to state that “mortality
    reduction data associated with spillover effects are not as
    robust as those analyzed for the direct effects of the proposed
    action.” For those reasons, the NMFS did not incorporate the
    estimated sea turtle mortalities that would be avoided due to
    a potential spillover effect into its population assessment
    models.
    The NMFS’s model showed the loggerhead species are
    on a path toward extinction, which accords with the fact that
    the NMFS recently raised the Pacific loggerhead’s ESA
    listing from “threatened” to “endangered.” The NMFS also
    found that “effects” to the loggerhead “are likely to occur as
    24 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    a result of worsening climate change,” which the NMFS
    “expect[s] to continue and therefore may impact sea turtles
    and their habitats in the future.” Rising levels of marine
    debris “could also increase entanglements.” Even though the
    NMFS was unable to quantify the risks of climate change
    and its associated impacts, the agency recognized that they
    would be detrimental to the loggerheads.
    The climate-based model predicted that the proposed
    action would exacerbate the loggerheads’ decline, and the
    BiOp is structurally flawed to the extent the NMFS failed to
    incorporate those findings into its jeopardy analysis. Nat’l
    Wildlife 
    Fed’n, 524 F.3d at 927
    . Because the NMFS has not
    articulated a rational connection between the best available
    science and its conclusion that the loggerhead sea turtles
    would not be affected by the increased fishing efforts, the
    agency’s determination that the loggerhead “population will
    remain large enough to retain the potential for recovery” is
    arbitrary and capricious.
    2. Leatherback Turtles
    Plaintiffs also argue that the 2012 BiOp improperly
    concluded that the fishery would have no appreciable impact
    on the leatherback turtle population. Unlike its conclusion
    concerning the loggerheads, however, the NMFS’s no
    jeopardy conclusion regarding the leatherback turtles finds
    support in the scientific record and, therefore, is sufficient to
    withstand judicial review.
    Plaintiffs specifically argue that the NMFS erred in
    limiting the “temporal scale” of its analysis to 25 years,
    despite the fact that the fishery’s operations have no related
    limitation and the NMFS determined that impacts on the sea
    turtles due to increasing temperatures “are expected to occur
    slowly over the next century.” However, the NMFS was
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 25
    entitled to rely on the climate-based population assessment
    model, even though that model could only predict changes
    in the turtle population for 25 years. See San Luis & Delta-
    Mendota Water Auth. v. Locke, 
    776 F.3d 971
    , 997 (9th Cir.
    2014) (“[T]he agency has substantial discretion to choose
    between available scientific models, provided that it explains
    its choice.”); The Lands Council v. McNair, 
    537 F.3d 981
    ,
    988 (9th Cir. 2008) (explaining that the court may not “act
    as a panel of scientists that instructs the [agency] how to . . .
    choose[] among scientific studies”), overruled on other
    grounds by Winter v. Nat. Res. Def. Council, Inc., 
    555 U.S. 7
    (2008). The constraints in the available data supply a
    reasonable justification for the NMFS to limit its analysis.
    Accordingly, we cannot conclude that the 2012 BiOp
    violated the ESA or that the NMFS otherwise acted
    arbitrarily and capriciously in determining that the fishery
    would have no appreciable effect on the leatherback turtle
    population.
    B. Consideration of the Effects of Climate Change
    Lastly, Plaintiffs argue that the 2012 BiOp failed to
    evaluate the impacts of global climate change. Plaintiffs
    specifically maintain that the NMFS acted arbitrarily by
    dismissing the effects of global warming on sea turtles as
    uncertain without further study.
    In the 2012 BiOp, the NMFS explained that the effects
    from climate change on listed turtle species include rising
    sand temperatures and sea levels, beach erosion, increased
    storm activity, and changes in ocean temperature and
    chemistry. The BiOp also summarized studies anticipating
    that climate change will impact, among other traits and
    behaviors, turtle gender ratios, nesting habitat, and
    reproductive capacity. However, the NMFS determined that
    there was no available data from which it could credibly
    26 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    project the impacts that climate change would have on the
    loggerhead or leatherback turtle survival rates. With respect
    to the loggerhead turtles, the NMFS explained that “current
    scientific methods are not able to reliably predict the future
    magnitude of climate change and associated impacts or the
    adaptive capacity of this species.” The NMFS also stated that
    “leatherbacks are probably already beginning to be affected
    by impacts associated with anthropogenic climate change in
    several ways,” but noted that it did “not have information to
    predict what the population would do” or “what impact other
    climate-related changes may have such as increasing sand
    temperatures, sea level rise, and increased storm events.” As
    the NMFS observed elsewhere in the BiOp, the effects of
    climate change will not be globally uniform, and the
    uncertainty of the rate, magnitude, and distribution of such
    effects on different temporal and spatial scales—not to
    mention the turtles’ ability to adapt to these effects—have
    not been comprehensively studied. Consequently, the NMFS
    decided that climate change effects could not be “reliably
    quantified” nor “qualitatively described or predicted” by the
    agency at the time.
    Here, we cannot conclude from the NMFS’s lack of
    precision that it failed to adequately consider the effects of
    climate change on the sea turtles. On the whole, the BiOp
    demonstrated that the NMFS considered a variety of ways in
    which climate change may affect the sea turtles, but simply
    concluded that the data available was too indeterminate for
    the agency to evaluate the potential sea-turtle impacts with
    any certainty. Cf. Greenpeace Action v. Franklin, 
    14 F.3d 1324
    , 1326–27, 1336 (9th Cir. 1993) (holding that the
    agency’s no jeopardy conclusion was not arbitrary because
    the BiOp at issue demonstrated that the agency had based its
    no jeopardy decision on the best available scientific data,
    even though the data was “uncertain”); Stop H-3 Ass’n v.
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 27
    Dole, 
    740 F.2d 1442
    , 1460 (9th Cir. 1984) (sustaining a
    BiOp that stated “we have very little data for providing an
    opinion, but feel it would be unreasonable to request [an
    additional] study which would be unlikely to provide
    definitive results. . . . Based on the available information,
    which we grant is weak, it is our opinion the proposed
    project is not likely to jeopardize the continued existence of
    the Oahu Creeper”). Plaintiffs have failed to sufficiently
    refute the NMFS’s stated inability to offer more specific
    predictions on the effects of climate change, and they have
    not alleged that less speculative scientific information is
    available that the agency overlooked. San Luis & Delta-
    
    Mendota, 747 F.3d at 602
    (“[W]here [superior] information
    is not readily available, we cannot insist on perfection: [T]he
    ‘best scientific . . . data available,’ does not mean the best
    scientific data possible.” (citation and internal quotation
    marks omitted)). Accordingly, the NMFS’s consideration of
    climate change in the BiOp was neither arbitrary, capricious,
    nor contrary to the NMFS’s obligation to base its jeopardy
    decision on the best scientific data it could obtain. See
    16 U.S.C. § 1536(a)(2).
    CONCLUSION
    We conclude that the FWS’s grant of an incidental take
    permit to the NMFS in reliance on the “special purpose
    permit” provision in 50 C.F.R. § 21.27 was arbitrary and
    capricious because the FWS’s interpretation of § 21.27 does
    not conform to either the MBTA’s conservation intent or the
    plain language of the regulation. We therefore reverse the
    district court’s grant of summary judgment affirming the
    FWS’s decision to issue the permit.
    We also conclude that NMFS’s 2012 BiOp’s no jeopardy
    finding as to the loggerhead sea turtles was arbitrary and
    capricious because the scientific data suggested that the
    28 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    loggerhead population would significantly decline, and the
    agency failed to sufficiently explain the discrepancy in its
    opinion and the record evidence. We therefore reverse the
    district court’s grant of summary judgment upholding this
    portion of the BiOp. We otherwise affirm the district court’s
    grant of summary judgment to Defendants.
    AFFIRMED in part; REVERSED in part; and

    appeal.
    CALLAHAN, Circuit Judge, dissenting in part:
    I agree with the majority that the 2012 Biological
    Opinion (“BiOp”) is not arbitrary and capricious in
    determining that the Hawaii-based shallow-set fishery
    expansion would have no appreciable effect on the
    leatherback sea turtle population, and that the 2012 BiOp
    adequately considers the impact of global climate change.
    However, I dissent from the remainder of the majority
    opinion.
    First, the majority errs in rejecting the U.S. Fish and
    Wildlife Service’s (“FWS”) issuance of a special purpose
    permit (the “Permit”) under the Migratory Bird Treaty Act
    (“MBTA”) to the National Marine Fisheries Service
    (“NMFS”) for the incidental take of migratory birds. The
    majority determines that issuing the Permit runs afoul of the
    pertinent regulation’s plain language and the MBTA’s
    conservation-oriented purpose. That conclusion, however,
    reflects a misapplication of our deferential standard of
    review under Auer v. Robbins, 
    519 U.S. 452
    (1997), because
    both the regulation—50 C.F.R. § 21.27—and the MBTA
    itself accommodate FWS’s view. See 
    Auer, 519 U.S. at 461

    Marsh v. J. Alexander’s LLC, 
    869 F.3d 1108
    , 1116–17 (9th
    Cir. 2017). Moreover, the Permit accords with FWS’s past
    practice, and thereby reflects its considered judgment—
    another basis for granting deference under Auer.

    132 S. Ct. 2156
    , 2166 (2012).
    Second, the majority errs in rejecting the 2012 BiOp’s
    assessment of the proposed shallow-set fishery expansion’s
    effects on the endangered loggerhead sea turtle. NMFS’s
    BiOp concludes that the proposed action would not
    jeopardize the continued survival and recovery of the
    loggerhead, as is required to green-light the project under the
    Endangered Species Act (“ESA”). The majority dismisses
    the BiOp as arbitrary and capricious because, among other
    things, it concludes that the scientific evidence does not
    support NMFS’s no-jeopardy conclusion, and it perceives a
    conflict with our case law. I disagree. While the record data
    shows that the loggerhead is in decline, NMFS reasonably
    concluded that the fishery expansion would not appreciably
    reduce the likelihood of the loggerhead’s survival and
    recovery. Nor did NMFS misapply our decision in National
    Wildlife Federation v. National Marine Fisheries Service,
    
    524 F.3d 917
    (9th Cir. 2008) (“NWF”): it considered the
    incremental impact of the proposed action along with
    degraded baseline conditions. That is precisely what NWF
    requires.
    The majority’s contrary conclusion is a classic example
    of the judiciary exceeding its authority by substituting an
    agency’s judgments with its own. This complex case relies
    on the technical and scientific findings of experts tasked with
    the responsibility of protecting our Nation’s species-in-peril.
    It is in this context that our respect for a coordinate branch
    of government is at its zenith. Indeed, we are “‘at our most
    deferential’ when reviewing scientific judgments and
    30 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    technical analyses within the agency’s expertise,” Lands
    Council v. McNair, 
    629 F.3d 1070
    , 1074 (9th Cir. 2010)
    (quoting Balt. Gas & Elec. Co. v. Natural Res. Def. Council,
    
    462 U.S. 87
    , 103 (1983)) (adjustment omitted) (“Lands
    Council II”), and should only reject an agency’s action if it
    is plainly arbitrary and capricious, see Motor Vehicle Mfrs.
    Ass’n of U.S., Inc. v. State Farm Mut. Auto. Ins. Co.,
    
    463 U.S. 29
    , 42–43 (1983). Yet instead of anchoring its
    analysis in well-established principles of agency deference,
    the majority sets sail on a voyage of discovery, leaving in its
    wake our precedent and the doctrinal moorings of Auer v.
    Robbins. I dissent, respectfully.
    I.
    A.
    Under Auer v. Robbins, we must defer to an agency’s
    reasonable interpretation of its own regulation. See
    
    Christopher, 132 S. Ct. at 2166
    . Deference is not warranted,
    however, “when the agency’s interpretation is plainly
    erroneous or inconsistent with the regulation,” or when it
    does not reflect the agency’s “considered judgment.” 
    Id. (internal quotation
    marks omitted). A lack of “considered
    judgment” may be evidenced by (i) an “agency[]
    interpretation [that] conflicts with a prior interpretation,”
    (ii) “when it appears that the interpretation is nothing more
    than a convenient litigating position,” or (iii) when the
    interpretation amounts to a “post hoc rationalization
    advanced by an agency seeking to defend past agency action
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 31
    against attack.” 
    Id. (internal quotation
    marks and adjustment

    At issue is FWS’s issuance of a special purpose permit
    allowing NMFS to authorize incidental take of migratory
    birds that are protected under the MBTA. 50 C.F.R. § 21.27
    authorizes FWS to issue permits for the take of migratory
    birds protected under the MBTA in certain circumstances.
    In full, the regulation provides that
    [p]ermits may be issued for special purpose
    activities related to migratory birds, their
    parts, nests, or eggs, which are otherwise
    outside the scope of the standard form
    permits of this part. A special purpose permit
    for migratory bird related activities not
    otherwise provided for in this part may be

    Auer’s continued vitality is a matter of considerable debate. Justice
    Antonin Scalia, the progenitor of the doctrine named after the 1997 case,
    Auer v. Robbins, which he authored, called for its abolition eighteen years
    later in Perez v. Mortgage Bankers Association, 
    135 S. Ct. 1199
    , 1213
    (2015) (Scalia, J., concurring). He appears to have shared this view with
    at least two other justices, Justices Samuel Alito and Clarence Thomas.
    See 
    id. at 1210
    (Alito, J., concurring); 
    id. at 1213
    (Thomas, J., concurring).
    See also John C. Eastman, The President’s Pen and the Bureaucrat’s
    Fiefdom, 40 HARV. J.L. & PUB. POL’Y 639, 641 (2017). Also, Justice Neil
    Gorsuch has openly criticized Chevron deference, see Gutierrez-Brizuela
    v. Lynch, 
    834 F.3d 1142
    , 1156 (10th Cir. 2016) (Gorsuch, J., concurring)
    (citing Marbury v. Madison, 
    5 U.S. 137
    (1803))—a less controversial
    deference doctrine because it provides for a check-and-balance between
    two branches of government (Congress and the Executive), whereas Auer
    involves the Executive’s interpretations of its own actions. At any rate,
    my conclusion that the Permit is a lawful exercise of FWS’s authority does
    not rely on the continued validity of Auer. Applying traditional tools of
    statutory construction, the Permit is lawful agency action because it is
    consistent with (i) the regulatory text of § 21.27, (ii) § 21.27’s greater
    context, and (iii) the purposes of both § 21.27 and the MBTA itself.

    application    containing      the    general
    information and certification required by part
    13 and makes a sufficient showing of benefit
    to the migratory bird resource, important
    research reasons, reasons of human concern
    for individual birds, or other compelling
    justification.
    50 C.F.R. § 21.27. The majority declines to defer to FWS’s
    issuance of the Permit because it finds that FWS’s action is
    plainly contrary to § 21.27 and the MBTA and is therefore
    ultra vires. Because I conclude that issuing the Permit does
    not depart from FWS’s past practice, is not inconsistent with
    § 21.27’s text, and comports with the MBTA’s conservation-
    oriented purpose, I would defer to FWS’s determination.
    1.
    Appellants Center for Biological Diversity, et al.
    (“CBD”) argue that FWS’s Permit should not be accorded
    Auer deference because, CBD asserts, it does not align with
    FWS’s past practice.
    To determine whether an agency has departed from past
    practice, the first step is—manifestly—to define the practice.
    
    Christopher, 132 S. Ct. at 2167
    –68. A practice is a policy or
    mode of operating that is defined by articulable parameters;
    simply showing that a current action differs from a prior one
    in some way does not establish a departure from past
    practice. Cf. FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 538 (2009) (agency departed from past practice by
    deeming broadcasts of non-literal uses of expletives as
    actionable only upon repetition); Dillmon v. Nat’l Transp.
    Safety Bd., 
    588 F.3d 1085
    , 1090–91 (D.C. Cir. 2009)
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 33
    (agency departed from past practice of deferring to an ALJ’s
    credibility determinations).
    CBD argues that by issuing the Permit, FWS has
    changed course from its prior position that it lacks authority
    to grant permits to allow unintentional bird taking—i.e.,
    incidental taking—for an activity that is not directed at
    migratory birds. The majority does not base its decision on
    this rationale and for good reason: FWS has long-issued
    incidental take permits for all manner of activities whose
    only relationship to migratory birds is that they affect the
    birds. For example, since at least 1996, FWS has authorized
    incidental take of migratory birds for commercial activities
    through Endangered Species Act (“ESA”) Habitat
    Conservation Plans (“HCPs”). 2 A benefit of entering into an
    HCP is that it comes with an ESA § 10 incidental take
    permit. See 16 U.S.C. § 1539(a)(1)(B), (a)(2). That permit
    “double[s]” as a § 21.27 special purpose permit under the
    MBTA. See Dep’t of Commerce, Habitat Conservation
    Plan Assurances (“No Surprises”) Rule, 63 Fed. Reg. 8859,
    8862–63 (Feb. 23, 1998). Critically, the take that occurs
    results from activities that are unrelated to migratory birds—
    e.g., natural gas drilling, homebuilding, and myriad other
    types of land development—except that they result in
    incidental bird deaths—the very ill that CBD insists infects
    the Permit at issue here.

    Handbook 16-9 (Dec. 21, 2016) (“2016 HCP Handbook”) (“FWS
    routinely issues consolidated ESA and [MBTA] permits for ESA-listed
    bird species.”).
    34 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    FWS has also issued incidental take permits for bald and
    golden eagles—which are migratory birds—for activities
    that, too, are not directed at migratory birds. See 50 C.F.R.
    §§ 22.11; 22.26. And in 1998, FWS issued a special purpose
    permit allowing the incidental take of migratory raptors by a
    wind farm due to collisions and electrocutions. See FWS
    Region 6, Fed. Fish & Wildlife Permit No. PRT-808690
    (1998). In short, CBD’s categorical assertion that “FWS has
    always understood [§] 21.27 does not authorize incidental
    take as the Permit allows” is plainly wrong.
    Identifying one error in CBD’s consistency-with-past-
    practice argument reveals another. CBD asserts that, “until
    [FWS] issued to NMFS the permit at issue exempting
    commercial longline fishing from the MBTA’s take
    prohibition, the only Special Use Permits FWS had ever
    issued authorizing incidental take of non-endangered
    migratory birds were specifically intended to promote
    migratory bird conservation . . . .” If CBD means to say that
    past permits were always associated with activities that had
    as their purpose bird conservation, then the preceding
    paragraph refutes this contention. But if CBD means
    something more capacious—i.e., that such activities must
    incorporate bird conservation strategies—then the Permit
    addresses this concern. NMFS regulates the Hawaii-based
    shallow-set longline fishery under a program that is
    expressly geared at reducing seabird bycatch. See 50 C.F.R.
    § 665.815(a)(1), (2), (4). Indeed, since the program took
    effect in 2004, incidental take of seabirds by the fishery has
    plunged nearly 90 percent. Thus, whatever CBD means by
    activities that “promote migratory bird conservation,”
    FWS’s issuance of the Permit is consistent with the agency’s
    historical practice of tying incidental take permits to
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 35
    conservation measures. If there is a past practice to be
    discerned, that is it. 3
    2.
    CBD insists that FWS’s past statements belie the
    agency’s assertion that the Permit accords with historical
    practice. CBD points to a 2009 regulation governing take
    under the Bald and Golden Eagle Protection Act
    (“BGEPA”). See Dep’t of the Interior, Eagle Permits; Take
    Necessary to Protect Interests in Particular Localities,
    74 Fed. Reg. 46,836, 46,862 (Sept. 11, 2009). BGEPA
    allows for the take of bald and golden eagles—which species
    also fall under the purview of the MBTA—pursuant to an
    MBTA permit. 50 C.F.R. § 22.11; see 50 C.F.R. § 22.26. In
    response to a public comment, the regulation’s preamble
    notes that “[n]o permit is currently available to authorize
    incidental take under the MBTA.” 74 Fed. Reg. at 46,862.
    CBD seizes on this language as evidence that the Permit is
    unlawful.
    CBD’s argument proves too much. If the cited statement
    means that FWS does not issue incidental take permits for
    migratory birds as a categorical rule, then all other instances
    3
    To be sure, what I articulate as FWS’s past practice does not
    precisely align with FWS’s own description of its policy for issuing special
    purpose permits, which broadly encompasses “incidental take of migratory
    birds” pursuant to agency “activities.” Courts are not permitted to make
    sense of an agency action by supplying a rationale not offered by the
    agency itself. Bowman Transp., Inc. v. Arkansas-Best Freight Sys., Inc.,
    
    419 U.S. 281
    , 285–86 (1974) (citing SEC v. Chenery Corp., 
    332 U.S. 194
    ,
    196 (1947)). But my description of the agency’s past practice does not
    supply a rationale for an otherwise arbitrary and capricious agency action.
    My observation that FWS’s issuance of the Permit is consistent with
    FWS’s historical policy simply demonstrates that CBD has not met its
    burden of showing that FWS has departed from past practice.
    36 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    of such permits would be unlawful. Yet CBD spills pages of
    ink distinguishing the Permit here from other take permits
    granted under the aegis of § 21.27, without suggesting that
    those permits are similarly unlawful. Moreover, under
    CBD’s interpretation, the cited statement is irreconcilable
    with FWS’s other pronouncements permitting take for, e.g.,
    migratory birds that are also ESA-listed species. See
    2016 HCP Handbook at 16-9. Cf. Boise Cascade Corp. v.
    EPA, 
    942 F.2d 1427
    , 1432 (9th Cir. 1991) (where possible,
    courts avoid statutory interpretations that result in
    inconsistencies).
    A more natural reading of FWS’s statements—and one
    that comports with FWS’s past practice—is that the agency
    recognizes that the MBTA lacks a programmatic framework
    for issuing incidental take permits.          To be sure, a
    comprehensive regulation governing incidental take would
    be preferable. It could set forth uniform criteria for issuing
    permits, thereby offering predictability for the regulated and
    environmental communities. 4 But the fact that there exists a
    better way to authorize incidental take does not mean that it
    is the only lawful way of doing so. Neither the majority nor
    CBD provides a persuasive explanation for why § 21.27
    does not support case-by-case issuance of permits
    authorizing incidental take. 5
    4
    FWS is in the process of drafting a regulation that would do just that,
    though it appears the process has stalled. See Dep’t of the Interior,
    Migratory Bird Permits; Programmatic Environmental Impact Statement,
    Notice of Intent, 80 Fed. Reg. 30,032 (May 26, 2015).
    5
    CBD also references statements from a 1996 version of FWS’s
    Habitat Conservation Handbook. The Handbook describes the process
    governing HCPs under the ESA. Because the Handbook is, at most, a
    guidance document, it lacks the force and effect of law. See Perez v.
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 37
    Undeterred, CBD takes aim at yet another non-MBTA
    regulation. This one—the so-called “No Surprises Rule”—
    implements the HCP provision of the ESA. See 63 Fed. Reg.
    at 8862–63. The rule explains that an ESA § 10 incidental
    take permit, issued in conjunction with an HCP, may
    “double” as a special purpose permit under the MBTA for
    ESA-listed species. FWS explains that issuing an ESA § 10
    permit in lieu of an MBTA § 21.27 special purpose permit is
    appropriate because the ESA is more species-protective than
    the MBTA. 
    Id. For example,
    HCPs require an “operating
    conservation program designed to conserve the species and
    minimize and mitigate the impacts of take of the listed
    species of migratory birds to the maximum extent
    practicable.” 
    Id. at 8863.
    CBD extracts from this statement
    the conclusion that special purpose permits may not be used
    to cover incidental take of non-ESA-listed species because
    such species will not enjoy the superior protections of the
    ESA.
    CBD’s reasoning founders on a logical fallacy. The No
    Surprises Rule provides that, because an ESA take permit
    comes with greater protections than an MBTA permit, a
    Mortg. Bankers Ass’n, 
    135 S. Ct. 1199
    , 1203–04 (2015); see generally
    1996 HCP Handbook. And to the extent it is probative of FWS’s “past
    practice,” it is of little value because the current Handbook is internally
    contradictory. One chapter states that “[n]on ESA-listed, migratory birds
    can be covered or otherwise addressed in the HCP and incidental take
    permit.” 2016 Handbook at 3-28. But another chapter states that “if an
    MBTA protected species is not ESA-listed, the FWS does not have a way
    to authorize incidental take.” 2016 Handbook at 7-7. An internal
    contradiction is archetypal evidence of a lack of “considered [agency]
    judgment,” and so the Handbook’s description of FWS’s MBTA
    permitting authority is neither persuasive nor deserving of deference. See
    
    Christopher, 132 S. Ct. at 2166
    .
    38 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    party need not also apply for an MBTA permit: the latter is
    subsumed under the former. See 
    id. at 8862–63.
    But that
    does not mean that ESA-level protections are necessary to
    authorize take under the MBTA. Put another way, the No
    Surprises Rule says nothing about whether it is appropriate
    to issue a special purpose permit for incidental take under
    the MBTA for non-ESA-listed species. 6
    By analogy, consider a hypothetical state’s labeling
    requirements for perishable foodstuffs.           The default
    regulation for all perishable foods requires the use-by date to
    be no more than thirty days from the sell-by date. But certain
    perishable foods are on a “highly perishable” list, and are
    subject to stricter regulations requiring the affixed use-by
    date to be no more than a week from the sell-by date. Now
    consider a particular perishable food that is not subject to the
    stricter regulations because it is not on the applicable list.
    Does this mean it is not governed by the laxer default rule?
    Not at all. Yet that is CBD’s logic here: that because the
    ESA’s heightened protections apply to some migratory
    birds, other non-ESA birds are not subject to the MBTA’s
    take provision. In fact, nothing about FWS’s incidental take
    policy toward ESA-listed migratory birds forecloses the
    6
    CBD offers no reason why the rationale for issuing ESA § 10 permits
    in lieu of an MBTA § 21.27 permit—that the ESA affords species greater
    protections—is not equally applicable to standalone § 21.27 permits for
    non-ESA-listed species. FWS, in its discretion, may require a § 21.27
    permittee to implement the same types of conservation measures that are
    codified under the ESA. FWS effectively did just that with the shallow-
    set fishery here. Because the fishery incorporates conservation measures
    that have dramatically reduced seabird bycatch, FWS’s issuance of the
    Permit is consistent with its rationale for covering migratory birds under
    ESA § 10.
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 39
    agency from issuing incidental take permits for non-ESA-
    listed migratory birds.
    B.
    While FWS’s issuance of the shallow-set fishery
    incidental take permit reflects its considered judgment and is
    consistent with its past practice, we may still be compelled
    to withhold deference if its interpretation of § 21.27 is
    “plainly erroneous or inconsistent with the regulation.”
    
    Christopher, 132 S. Ct. at 2166
    (internal quotation marks
    omitted). The majority relies on this rationale in concluding
    that we should not afford FWS’s action Auer deference, but
    its reasoning is based on flawed logic and a misinterpretation
    of the MBTA.
    1.
    The majority claims that the “special purpose activit[y]”
    exception to the general ban on permitting take does not
    apply here because fishing lacks an “articulable special
    purpose.” What qualifies a purpose as “special”? The
    majority never quite answers this question, except to
    obliquely note that “special purpose” must be read “in the
    context of the regulation’s other requirements . . . .” Those
    requirements are, according to the majority, that the activity
    authorized by the permit “relate[] to migratory birds,” be
    paired with a “compelling justification,” and have a
    conservation purpose. 7 But the majority never explains what
    7
    See Klem v. City of Santa Clara, 
    208 F.3d 1085
    , 1092 (9th Cir. 2000)
    (“the question . . . is whether the Secretary’s interpretation is justified
    when considered together with the text of [the regulation], taken in
    context”); cf. FDA v. Brown & Williamson Tobacco Corp., 
    529 U.S. 120
    ,
    133 (2000) (noting the “fundamental canon of statutory construction that
    40 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    it means to “relate[] to migratory birds,” except to posit a
    proposition in the negative—namely, that not all activities
    that risk killing migratory birds “relate[] to those birds.”
    Landowners, environmental practitioners, and FWS will be
    hard-pressed to decipher this delphic explanation. Do some
    activities that do not have as their purpose the conservation
    of migratory birds “relate to those birds”? Which ones? And
    how do we know?
    The Auer inquiry is more straightforward. We consider
    the agency’s interpretation relative to the regulation and the
    governing statute. 
    Marsh, 869 F.3d at 1116
    –17. We must
    assure ourselves that the agency has fairly construed its own
    regulation, while also keeping one eye trained on Congress’
    intent. 
    Id. To that
    end, “‘[we] need not accept an agency’s
    interpretation of its own regulations if that interpretation is
    . . . inconsistent with the statute under which the regulations
    were promulgated.’” 
    Id. at 1117
    (quoting Mines v. Sullivan,
    
    981 F.2d 1068
    , 1070 (9th Cir. 1992)).
    My analysis proceeds as follows: I disaggregate § 21.27
    into its relevant textual parts, consider each part against the
    regulation’s broader structure and context, and then assess
    FWS’s interpretation against the MBTA.
    •   “Permits may be issued for special purpose activities
    . . . which are otherwise outside the scope of the
    standard form permits of this part.” The regulation
    does not define “special purpose activit[y].” It is also a
    regulatory term of art that is not susceptible to
    interpretation by reference to dictionary definitions.
    the words of a statute must be read in their context and with a view to their
    place in the overall statutory scheme” (internal quotation marks omitted)).
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 41
    Deploying a wider net, we expand our analysis to the
    regulation’s structure and context. The latter part of the
    sentence is instructive. It indicates that a “special
    purpose activit[y]” is one that is not covered by an
    expressly identified permitting scheme. Contrary to
    CBD’s assertion, nothing in the context of the regulation
    indicates that to be “special” an activity’s purpose must
    be directed at migratory birds. 8 See 
    Klem, 208 F.3d at 1092
    .
    •   Special purpose permits must be “related to migratory
    birds . . . .” The term “relate” has several dictionary
    definitions (an inauspicious start for the majority),
    including, as is pertinent here: “[t]o refer to,” “[t]o have
    reference to,” “[t]o have some connection with; to stand
    in relation to,” or “[t]o connect, to link; to establish a
    relation between.” Oxford English Dictionary (3d ed.
    2009) (goo.gl/grzBqC) (last accessed Dec. 8, 2017).
    Whether the first two definitions could flex to embrace
    an activity whose purpose is not directed at migratory
    birds is debatable. But we need not parse those
    definitions because the last two plainly do: an activity
    like commercial fishing indisputably has “some
    connection with” migratory birds.
    • An applicant for a special purpose permit must
    “make[] a sufficient showing of benefit to the migratory
    bird resource, important research reasons, reasons of

    CBD asserts that an “ongoing fishing business . . . has no ‘special
    purpose’ beyond catching fish.” But this observation only begs the
    question: what is a “special purpose”? CBD offers no explanation, except
    to march out a parade of horribles, warning that if the Permit is allowed to
    stand then the court will have ushered in a brave new world in which
    “every activity that happens to somehow harm birds” will qualify for an
    incidental take permit.
    42 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    human concern for individual birds, or other
    compelling justification.” FWS invoked the “other
    compelling justification” category as the regulatory hook
    for issuing the Permit. FWS discerned a “compelling
    justification” in its determination that the Permit would
    “provide a[n economic] net benefit to the Nation” and
    would “serve[] as a benchmark internationally for
    employing effective seabird mitigation techniques and
    serves as an example of responsible conservation
    practices by a fishery.”
    The majority concludes that FWS’s rationale is
    inadequate, observing that FWS fails to “read the ‘special
    purpose’ provision in the context of the regulation’s other
    requirements that, taken together, fail to turn § 21.27 into a
    general incidental take exception.” 9 The problem for CBD
    and the majority, however, is that nothing in § 21.27
    suggests—let alone requires—that all special purpose
    activities must have as their objective migratory bird
    conservation to satisfy the “compelling justification”
    standard. In fact, § 21.27's text reveals just the opposite.
    The first eligible category is for activities that provide a
    “benefit to the migratory bird resource.” Thus, one type of
    permit is for an activity that is directed at bird conservation.
    But another listed category—“important research
    reasons”—includes not even a gloss of conservation intent.
    Nor does anything in § 21.27 indicate that a characteristic of
    the first stand-alone category—“benefit to the migratory bird
    resource”—modifies all those that follow. Rather, the most
    natural reading is that special purpose permits are
    9
    The majority correctly adheres to the doctrine that “all the words
    used in a list should be read together and given related meaning when
    construing a statute or regulation.” Aguayo v. U.S. Bank, 
    653 F.3d 912
    ,
    927 (9th Cir. 2011).
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 43
    appropriate for activities that are either directed at bird
    conservation or at other activities that may or may not have
    a conservation purpose—e.g., scientific research.
    Lest there be any doubt, the immediately following
    subsection makes clear that permits may be issued for non-
    conservation-related purposes. Section 21.27(a) describes
    the criteria for issuing a special purpose permit. See
    50 C.F.R. § 21.27(a). It explains that such a permit “is
    required before any person may sell, purchase, or barter
    captive-bred, migratory game birds . . . .” 
    Id. Nothing in
    this subsection suggests that selling, purchasing, or bartering
    birds serves the purpose of conserving those birds. Nor do
    those terms have an inherent conservation-oriented
    meaning—quite the opposite. 10
    In sum, the catch-all category “other compelling
    justification” is not limited to activities whose purpose is
    conserving migratory birds. And the majority provides no
    other limiting condition, except to warn against transforming
    § 21.27 into a “general incidental take exception.” But no
    party argues that § 21.27 grants FWS a roving license to
    permit incidental take whenever it chooses. The question is,
    instead: where the agency’s interpretation is not
    irreconcilable with the regulation’s text and reflects the
    agency’s “considered judgment” (i.e., it is consistent with
    past practice), who gets to decide, the courts or the agency?
    Auer provides the answer: we defer to the agency in which
    Congress has vested regulatory authority to craft policy
    based on its expert judgment. See 
    Christopher, 132 S. Ct. at 2166

    To be sure, the quoted phrase applies only to captive-bred birds.
    But the point is that the regulation expressly contemplates issuing special
    purpose permits for something other than conserving migratory birds.

    conclude that FWS’s interpretation of “other compelling
    justification” as including economic benefits and the benefit
    of teaching other nations good conservation techniques is not
    “plainly erroneous or inconsistent with the regulation.”

    2.
    The Permit also comports with the MBTA’s
    conservation purpose. The majority is correct that in passing
    the MBTA Congress sought to promote migratory bird
    conservation. 11 But the statute also expressly provides for
    non-conservation-related take of migratory birds. As is
    relevant here, the MBTA allows FWS to consider economic
    factors in determining whether to permit, among other
    things, the taking, killing, possessing, or sale of migratory
    birds or their parts. 16 U.S.C. § 704(a). Stated in full,
    § 704(a) provides that:
    Subject to the provisions and in order to carry
    out the purposes of the [migratory bird treaty]
    conventions . . . the [FWS] is authorized and
    directed, from time to time, having due
    regard to the zones of temperature and to the
    distribution, abundance, economic value,
    breeding habits, and times and lines of
    migratory flight of such birds, to determine
    11
    See Humane Soc’y of U.S. v. Watt,

    (D.C. Cir. 1983) (“‘The United States . . . [and]
    Great Britain . . . , being desirous of saving from indiscriminate slaughter
    and insuring the preservation of such migratory birds as are either useful

    protection which shall effectively accomplish such objects . . . .’”)

    when, to what extent, if at all, and by what
    means, it is compatible with the terms of the
    conventions to allow hunting, taking,
    capture, killing, possession, sale, purchase
    shipment, transportation, carriage, or export
    of any such bird, or any part, nest, or egg
    thereof, and to adopt suitable regulations
    permitting and governing the same . . . .
    
    Id. (emphasis added).
    But how—the reader may ask—can we reconcile the
    statute’s conservation-oriented focus with its provisions
    allowing for the killing of migratory birds? One way is to
    interpret § 704(a) as permitting bird deaths—by way of
    hunting, incidental take, or other means—to the extent that
    doing so does not threaten the overall conservation of
    migratory birds. Indeed, we would not be the first court to
    adopt this interpretation. See Humane Soc’y v. Watt, 551 F.
    Supp. 1310, 1319 (D.D.C. 1982), aff’d, 
    713 F.2d 865
    (D.C.
    Cir. 1983) (“It does not necessarily follow from the MBTA’s
    evident purposes of conservation that the statute creates a
    presumption against hunting . . . .”).
    The Permit is consistent with this accommodation of
    competing statutory directives: it allows for the take of
    migratory birds when paired with measures designed to
    minimize such take. Neither CBD nor the majority contends
    that, if such measures are followed, the MBTA’s broad goal
    of conserving migratory birds is threatened.
    3.
    The majority has one lure left in its tackle box, but I
    decline to take the bait. The majority suggests that because
    the MBTA generally prohibits take, a presumption attaches
    46 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    against reading § 21.27 as authorizing incidental take. The
    majority reasons that “although § 21.27 is intended to allow
    the FWS to authorize activities not otherwise permitted by
    the regulations, it is still a narrow exception to the MBTA’s
    general prohibition on killing migratory birds.”
    While it is true that the MBTA generally prohibits taking
    migratory birds, the majority’s observation is a red herring
    because the statute and regulations provide for numerous
    exceptions to the general rule. 12 The pertinent question turns
    on the scope of the exception to the prohibition, not the
    existence of the general prohibition in the first place. As
    discussed, § 21.27 is ambiguous and accommodates FWS’s
    view that the Permit supports a “special purpose activit[y]”
    that is anchored in a “compelling justification.”
    *     *     *
    Because issuing the Permit follows FWS’s past practice,
    is not plainly erroneous or inconsistent with § 21.27, and
    comports with the MBTA’s conservation-oriented purpose,
    I would hold it to be a lawful exercise of FWS’s authority.
    12
    See 16 U.S.C. § 703(a) (“except as permitted by regulations . . . it

    TURTLE ISLAND RESTORATION NETWORK V. USDOC 47
    II.
    The majority also errs in rejecting NMFS’s loggerhead
    turtle BiOp as arbitrary and capricious. The majority’s
    analysis rests on a misapprehension of both binding case law
    and the administrative record in this case.
    Section 7(a)(2) of the ESA requires all federal agencies
    to ensure that any discretionary “action” they authorize,
    fund, or implement does not “jeopardize the continued
    existence” of an ESA-listed species. 16 U.S.C. § 1536(a)(2);
    50 C.F.R. § 402.03. 13 To “jeopardize” means “to engage in
    an action that reasonably would be expected, directly or
    indirectly, to reduce appreciably the likelihood of both the
    survival and recovery of a listed species in the wild by
    reducing the reproduction, numbers, or distribution of that
    species.” 50 C.F.R. § 402.02. Put another way, “[t]o
    ‘jeopardize’—the action ESA prohibits—means to ‘expose
    to loss or injury’ or to ‘imperil.’” 
    NWF, 524 F.3d at 930
    . As
    we have previously explained,
    [e]ither of these [terms] implies causation,
    and thus some new risk of harm. Likewise,
    the suffix “-ize” in “jeopardize” indicates
    some active change of status: an agency may
    not “cause a species to be or to become” in a
    state of jeopardy or “subject a species to”
    jeopardy . . . .
    [A]n agency may not take action that will
    tip a species from a state of precarious
    survival into a state of likely extinction.
    13
    “Section 7 . . . appl[ies] to all actions in which there is discretionary
    Federal involvement or control.” 50 C.F.R. § 402.03.
    48 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    Likewise, even where baseline conditions
    already jeopardize a species, an agency may
    not take action that deepens the jeopardy by
    causing additional harm.
    
    Id. (emphasis added).
    Our discussion of “jeopardy” in NWF must be read in the
    context of the regulatory standard. To “deepen[] the
    jeopardy” of a species is to “reduce appreciably” a species’
    chance at continued survival and recovery. See 50 C.F.R.
    § 402.02. It cannot—as CBD and the majority suggest—
    simply mean exacerbating a species’ already “imperiled”
    existence, no matter how de minimis the impact. An
    “endangered species” like the loggerhead is, by definition, a
    “species which is in danger of extinction throughout all of a
    significant portion of its range.” 16 U.S.C. § 1532(6)
    (defining “endangered”). If the ESA prohibited any action
    that worsened—no matter how marginally—a species’
    current plight, then it is difficult to conceive of an action that
    could survive § 7 consultation. That is not the standard: the
    question is not whether the agency action will negatively
    affect the species, but whether in doing so it will appreciably
    reduce its likelihood of survival and recovery. 
    NWF, 524 F.3d at 930
    (the operative inquiry is whether the action
    will “cause[] some new jeopardy”—i.e., whether it will “tip
    a species from a state of precarious survival into a state of
    likely extinction” (emphasis added)).
    In NWF, we rejected a BiOp that excluded certain
    discretionary agency actions from the jeopardy analysis, and
    which also failed to consider degraded baseline conditions.
    
    Id. at 933.
    The BiOp assessed the effects of dam operations
    on the Chinook salmon, an ESA-listed species. 
    Id. at 925–
    26. We faulted NMFS for departing from its past practice
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 49
    and taking a novel approach in evaluating dam operation
    impacts. First, NMFS labeled several operations as
    nondiscretionary, thereby “excluding them from the
    requisite ESA jeopardy analysis.” 
    Id. at 928–29.
    Second,
    NMFS considered only the marginal impact of certain
    discretionary dam operations in its jeopardy analysis. 
    Id. at 929–30.
    As concerns the second error, NMFS considered
    only whether those actions were “‘appreciably’ worse than
    baseline conditions.” 
    Id. at 930.
    Only if they were would
    NMFS then conduct a jeopardy analysis. 
    Id. We held
    that NMFS’s methodology collided with the
    plain text of the regulations. Section 402.02 explains that an
    agency action “jeopardizes” a species if it “reduce[s]
    appreciably the likelihood of” the species’ “survival and
    recovery,” when considering the action’s direct, indirect, and
    cumulative impacts measured against the environmental
    baseline. 50 C.F.R. §§ 402.02; 402.14(g)(4). NMFS
    executed a different procedure. Instead of weighing the
    proposed action in the context of the species’ continued
    existence, it assessed the action against then-current baseline
    conditions. See 
    NWF, 524 F.3d at 930
    .
    By way of example, consider a hypothetical scenario in
    which a residential subdivision is planned for an area
    inhabited by the endangered arroyo toad. See Rancho Viejo,
    LLC v. Norton, 
    334 F.3d 1158
    , 1160 (D.C. Cir. 2003)
    (Roberts, J., dissenting from denial of rehearing en banc).
    The development requires a federal permit, thereby
    triggering ESA § 7 consultation. Sierra Club v. Bureau of
    Land Mgmt., 
    786 F.3d 1219
    , 1224 (9th Cir. 2015)
    (consultation required where a private project is “funded,
    authorized, or constructed by any federal agency”). The toad
    is already threatened by the combined effects of climate
    50 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    change and habitat fragmentation. 14 Existing developments
    have substantially reduced the toad’s habitat, and it teeters
    on the precipice between survival and extinction. The
    proposed development would reduce the toad’s habitat by an
    additional 10 percent, which, in the agency’s estimation,
    does not amount to an “appreciable” negative impact when
    compared to the habitat destruction that has already taken
    place. Thus, under the methodology rejected by this court in
    NWF, the agency would not have engaged in a jeopardy
    analysis.
    The pertinent question under NWF, however, is whether
    the proposed development would have an appreciable
    impact on the toad’s survival and recovery. Comparing only
    the marginal impact against already degraded baseline
    conditions conceals this inquiry. Only by considering the
    impact of the proposed development “‘within the context of
    other existing human activities that impact the listed
    species’”—i.e., in the context of climate change effects and
    an already diminished natural habitat—can the agency
    determine whether the proposed action will consign the toad
    to a fate of oblivion. See 
    NWF, 524 F.3d at 930
    . Similarly,
    the flaw NWF identified in that case was NMFS’s failure to
    account for the “existing human activity” of dam operations,
    which impacted the salmon’s survival. See 
    id. at 930–31.
    The court held that NMFS should have considered the
    proposed agency action—continued dam operations—
    together with degraded baseline conditions, instead of
    against those conditions. See 
    id. at 931.
    Turning to the matter before us, NMFS undertook the
    analysis required by NWF. NMFS considered, among other
    14
    See U.S. Fish and Wildlife Service, Arroyo Toad 5-Year Review:
    Summary and Evaluation 10, 16 (Aug. 2009).
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 51
    things, the (i) the current status of the loggerhead sea turtle,
    (ii) the direct effects of the proposed action on the
    loggerhead based on climate-based and classical modeling,
    (iii) the impact of climate change and other cumulative
    effects, and (iv) whether the proposed action would result in
    an appreciable reduction in the likelihood of the
    loggerhead’s survival and recovery. The majority arrives at
    a contrary conclusion by fixating on the BiOp’s statement
    that the incremental harm of the proposed action is “the
    death of a single adult, female loggerhead per year,” which
    is an “‘extremely small . . . level of take from the action.’”
    The majority insists that NMFS ran afoul of NWF by
    comparing the marginal impact of the fishery “to the much
    greater harm resulting from factors beyond the fishery.” But
    NMFS’s consideration of the marginal impact of the fishery
    did not drive its jeopardy analysis à la NWF. Instead, NMFS
    considered the “adverse effect on the overlying population
    . . . when considered together with all impacts considered in
    the Status of the Species, Baseline and Cumulative Effects
    sections, including other federally authorized fisheries and
    foreign fisheries.” NMFS explained that,
    [d]espite the projected population decline
    over one generation, we expect the overall
    population to remain large enough to
    maintain genetic heterogeneity, broad
    demographic representation, and successful
    reproduction. The proposed action will have
    a small effect on the overall size of the
    population, and we do not expect it to affect
    the loggerheads’ ability meet their lifecycle
    requirements and to retain the potential for
    recovery.
    52 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    Thus, unlike in NWF, where NMFS failed to consider direct,
    indirect, and cumulative effects, here, NMFS incorporated
    the marginal impact of the fishery in assessing whether the
    action—combined with baseline conditions—would “tip
    [the loggerhead] from a state of precarious survival into a
    state of likely extinction.” See 
    id. at 930.
    It concluded it
    would not, and we owe that determination deference. 15 See
    Lands Council 
    II, 629 F.3d at 1074
    (“Review under the
    arbitrary and capricious standard is narrow and we do not
    substitute our judgment for that of the agency.”) (internal
    quotation marks omitted)).
    The majority also criticizes NMFS for relying on “the
    conservative nature of its calculations to support the
    difference between its conclusion and the climate-based
    model’s results.” As a first matter, the majority does not
    explain where the model results diverge from NMFS’s
    finding of no-jeopardy. Nor could it plausibly do so: an
    15
    NMFS included in its analysis an assessment of “spillover”
    effects—i.e., the impact of the expanded domestic shallow-set fishery on
    foreign fisheries. NMFS found that without the expansion, foreign
    fisheries would move in and occupy the area. And because the implicated
    foreign nations generally have weaker environmental laws than does the
    United States, NMFS concluded “with reasonable certainty, that [under the
    agency action] there will be a reduction of [loggerhead and leatherback sea
    turtle] mortalities as a result of the spillover effect.” NMFS estimated the
    reduction to be “11 fewer interactions in the central and north Pacific . . .
    or four fewer [loggerhead and leatherback sea turtle] mortalities.”
    This data amply supports NMFS’s no-jeopardy conclusion. However,
    NMFS did not incorporate its findings into the jeopardy analysis because
    it concluded that “data on foreign fisheries is likely incomplete or
    inaccurate.” Thus, while the “spillover” effects data is compelling, I—like
    the agency—do not rely on it in assessing the reasonableness of NMFS’s
    ultimate determination.
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 53
    analysis of the record data in the BiOp supports NMFS’s
    conclusion. The climate-based model showed that, in 99.5
    percent of the tests, the loggerhead would fall below the
    quasi-extinction threshold (“QET”) in 25 years without the
    proposed action. NMFS similarly found that “[w]hen the
    same model is run with the proposed action, the mortality of
    1 adult female, the results are similar with 99.5% to 100%
    of the runs falling below the QET.” 16 Indeed, the model
    showed that while the proposed action would have a
    “detectable influence on the loggerhead population, there is
    no significant difference in the risk of extinction between the
    default, climate-based trends and the forecast considering
    the direct effects of the proposed action.” In other words,
    the risk of extinction is virtually the same whether or not the
    shallow-set fishery is expanded. Accordingly, NMFS
    reasonably concluded that the proposed action would not
    “reduce appreciably the likelihood” of the loggerheads’
    “survival and recovery.” See 50 C.F.R. § 402.02.
    At any rate, the majority is simply wrong that NMFS
    relied on its conservative estimates to arrive at its no-
    jeopardy conclusion. In fact, NMFS relied on (i) the results
    of the climate change model showing no statistically
    significant difference in the risk of extinction to the
    loggerhead with or without the proposed agency action; and
    16
    The additional loss of one adult female per annum from the
    proposed action results in a projected reduction in the overall population
    of 4 to 11 percent, due to a loss of that single turtle’s “reproductive
    potential” over the course of generations. But, contrary to the majority’s
    assessment, NMFS did not credit this numerical loss because it had low
    confidence in the data. NMFS noted that the estimated loss does “not
    account for the high mortality rate expected of these hatchlings from other
    sources, including climate-based threats.” In other words, the reduction
    due to a loss of reproductive potential is significantly overstated.
    54 TURTLE ISLAND RESTORATION NETWORK V. USDOC
    (ii) a “qualitative analysis” reflecting that the loss of one
    additional female loggerhead per year would still allow the
    loggerhead population to “remain large enough to maintain
    genetic heterogeneity, broad demographic representation,
    and successful reproduction.” 17
    Accordingly, because NMFS’s path “may reasonably be
    discerned” and “a reasonable basis exists for its decision,” I
    would affirm NMFS’s loggerhead BiOp. Pac. Coast Fed’n
    of Fishermen’s Ass’ns v. Blank,

    (1974) (“[W]e will uphold a decision of less
    than ideal clarity if the agency’s path may reasonably be
    discerned.”).
    17
    NMFS’s use of conservative data inputs is relevant not because it is
    the sole basis for its no-jeopardy conclusion (as discussed, it isn’t), but
    because it reflects the reasonableness of its findings. For example, NMFS
    considered the lost “reproductive potential” of all “unborn hatchlings,”
    even though hatchlings have a “high mortality rate.” It also assumed that
    the shallow-set fishery would immediately operate at 5,500 sets every
    year, even though the increase is likely to be gradual over time. And its
    climate model did not incorporate the results of anticipated indirect
    effects—namely, beneficial “spillover” effects—of the domestic fishery’s
    displacement of international fisheries.
    As discussed, NMFS’s no-jeopardy conclusion is not unreasonable
    even without considering the conservative nature of its inputs.
    Recognizing that those inputs are more conservative than actual conditions
    warrant therefore only weakens the majority’s erroneous conclusion that
    NMFS’s action is arbitrary and capricious. See George v. Bay Area Rapid
    Transit, 
    577 F.3d 1005
    , 1011 (9th Cir. 2009) (“The party challenging an
    agency’s action as arbitrary and capricious bears the burden of proof
    . . . .”).
    TURTLE ISLAND RESTORATION NETWORK V. USDOC 55
    CONCLUSION
    FWS acted within its authority when it issued a special
    purpose permit to NMFS under the MBTA. Its decision
    aligns with past practice, is not “plainly erroneous or
    inconsistent with [50 C.F.R. § 21.27],” and comports with
    the MBTA’s conservation-oriented purpose. The majority
    errs in holding otherwise. Similarly, NMFS’s no-jeopardy
    finding for the loggerhead sea turtle is rationally related to
    the evidence in the record, satisfies its statutory obligation to
    consider direct, indirect, and cumulative impacts, and is
    faithful to our decision in NWF. Because we should uphold
    the MBTA Permit and the loggerhead BiOp, I must
    respectfully dissent.
