SUPPLEMENTARY INFORMATION:

Background

    On February 26, 2019, we, the U.S. Fish and Wildlife Service 
(Service), published in the Federal Register a final rule under the 
Endangered Species Act

[[Page 11675]]

of 1973, as amended (Act; 16 U.S.C. 1531 et seq.) (84 FR 6278; 
hereafter referred to as ``the 2019 rule''). The 2019 rule was the 
outcome of a rulemaking proceeding that began with a proposed rule (77 
FR 40222, July 6, 2012) and a revised proposed rule (81 FR 20302, April 
7, 2016).
    The 2019 rule revised the List of Endangered and Threatened 
Wildlife in title 50 of the Code of Federal Regulations (at 50 CFR 
17.11(h)) to:
     Add the northern subspecies of scarlet macaw (A. m. 
cyanoptera) as an endangered species;
     Add the northern distinct population segment (DPS) of the 
southern subspecies (A. m. macao) as a threatened species; and
     Add the southern DPS of the southern subspecies (A. m. 
macao) and subspecies crosses (A. m. cyanoptera and A. m. macao) as 
threatened species due to similarity of appearance to the northern 
subspecies (A. m. cyanoptera) and to the northern DPS of the southern 
subspecies (A. m. macao).
    The 2019 rule also added protective regulations to 50 CFR 17.41 
pursuant to section 4(d) of the Act for the northern and southern DPSs 
of the southern subspecies and for subspecies crosses (hereafter, ``the 
4(d) rule''). For a more thorough discussion of the taxonomy, life 
history, distribution, and the determination of listing status for 
scarlet macaws under the Act, please refer to the 2019 rule.
    In the 2019 rule, we determined that the northern DPS of the 
southern subspecies of scarlet macaw met the definition of a threatened 
species because it was likely to become in danger of extinction within 
the foreseeable future throughout all of its range. In response to 
litigation, on April 3, 2023 (88 FR 19549), we published additional 
analyses and a final threatened species determination for the northern 
DPS of the southern subspecies of scarlet macaw.
    As part of a lawsuit in the United States District Court for the 
District of Columbia that challenged the macaw listing (Friends of 
Animals v. Williams (No. 1:21-cv-02081-RC) (Friends of Animals)), on 
July 10, 2024, the court found that the 2019 rule was flawed in part 
because it did not include an explanation as to why we decided not to 
consider listing the northern DPS of the southern subspecies as an 
endangered species based on similarity of appearance to the northern 
subspecies. The court remanded the 2019 rule back to us for further 
explanation on this issue. However, the court did not vacate the 2019 
rule, instead finding that ``the deficiency identified in the 2019 
Final Rule--the Service's lack of explanation for why it decided not to 
consider listing the Northern DPS as endangered based on similarity of 
appearance--is relatively minor and also has `a real possibility of 
being cured by further explanation on remand.' . . . On remand, the 
Service may, for instance, be able to explain why it exercised its 
significant discretion not to consider a similarity-of-appearance 
listing for the Northern DPS, or it may decide to reconsider uplisting 
the Northern DPS based on such a rationale.'' Subsequently, on October 
8, 2024, the court ordered the Service to submit to the Office of the 
Federal Register no later than March 7, 2025, a ``notice opening a 30-
day public comment period on either (1) a draft ESA Section 4(e) 
analysis for the Northern DPS, or (2) an explanation regarding why the 
Service exercised its significant discretion not to consider a 
similarity-of-appearance listing for the Northern DPS.''
    Accordingly, this document provides the court-ordered explanation 
as to why we did not consider a similarity-of-appearance listing as 
endangered under section 4(e) for the northern DPS of the southern 
subspecies in addition to the determination of threatened status under 
section 4(a). We are providing this explanation in compliance with the 
district court's order. The government filed a notice of appeal of the 
district court's order on December 5, 2024, but have not yet received 
authorization from the Office of the Solicitor General to pursue the 
appeal. If the Solicitor General does not authorize appeal, we will 
voluntarily dismiss the appeal. By providing this explanation, we are 
not indicating our agreement with the district court's holding. As 
addressed further below, it is our position that section 4(e) of the 
Act does not provide us with authority to treat a threatened species 
listed pursuant to section 4(a) of the Act as an endangered species 
based on similarity of appearance to an endangered species. Therefore, 
we do not intend in future rulemakings to provide explanations as to 
why we did not consider treating other species as endangered under 
section 4(e) of the Act if those species separately warrant listing as 
threatened species under section 4(a) of the Act.
    For a description of previous Federal actions concerning the 
scarlet macaw, please refer to:
     the 2022 notification of additional analysis (87 FR 66093, 
November 2, 2022),
     the 2023 significant portion of the range (SPR) analysis 
(88 FR 19549, April 3, 2023), and
     the 2024 opening of a comment period on the 2023 SPR 
analysis (89 FR 104950, December 26, 2024).

Explanation

    With this document, we hereby open a 30-day public comment period 
on our explanation as to why we did not consider a similarity-of-
appearance listing for the northern DPS of the southern subspecies of 
scarlet macaw under section 4(e) of the Act.
    Section 4 of the Act (16 U.S.C. 1533) and the implementing 
regulations in title 50 of the Code of Federal Regulations set forth 
the procedures for determining whether a species is an endangered 
species or a threatened species, issuing protective regulations for 
threatened species, and designating critical habitat for endangered and 
threatened species.
    The Act defines an ``endangered species'' as a species that is in 
danger of extinction throughout all or a significant portion of its 
range and a ``threatened species'' as a species that is likely to 
become an endangered species within the foreseeable future throughout 
all or a significant portion of its range (16 U.S.C. 1532(6), (20)). 
The Act requires that we determine whether any species is an endangered 
species or a threatened species because of any of the following factors 
in section 4(a):
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;
    (B) Overutilization for commercial, recreational, scientific, or 
educational purposes;
    (C) Disease or predation;
    (D) The inadequacy of existing regulatory mechanisms; or
    (E) Other natural or manmade factors affecting its continued 
existence.
    These factors represent broad categories of natural or human-caused 
actions or conditions that could have an effect on a species' continued 
existence. In evaluating these actions and conditions, we look for 
those that may have a negative effect on individuals of the species, as 
well as other actions or conditions that may ameliorate any negative 
effects or may have positive effects.
    Section 2 of the Act states that the purposes of the Act include 
providing a means to conserve the ecosystems upon which endangered and 
threatened species depend, developing a program for the conservation of 
listed species, and achieving the purposes of certain treaties and 
conventions (16 U.S.C. 1531(b)). The ultimate goal of conservation 
efforts is the recovery of listed species, so that they no longer need 
the protective measures of the Act.

[[Page 11676]]

The Act provides multiple tools to conserve species that warrant 
protection under section 4(a) and have been added to the List of 
Endangered and Threatened Wildlife (50 CFR 17.11) or List of Endangered 
and Threatened Plants (50 CFR 17.12). These include (among other 
protections) designation of critical habitat, recovery planning under 
section 4(f), protective regulations for threatened species under 
section 4(d), and Federal agency requirements to ensure their actions 
are not likely to jeopardize the continued existence of listed species 
or destroy or adversely modify their critical habitat under section 
7(a)(2).
    One of these tools, section 4(e), provides us with the discretion 
to treat species as endangered species or threatened species when they 
are not listed under section 4(a). This authority to treat species as 
endangered or threatened when they are similar in appearance to (i.e., 
resemble) a species that is listed under section 4(a) is limited to 
situations when treating the species as endangered or threatened under 
section 4(e) could help protect the listed species that it resembles. 
In other words, under section 4(e), we may treat an unlisted species as 
an endangered or threatened species if doing so will facilitate 
enforcement of the Act for the benefit of, and reduce threats to, the 
species listed under section 4(a). The Act's tools and protections for 
endangered and threatened species are directed at the species that meet 
the definitions of endangered species or threatened species under 
section 4(a), not the species that are treated as endangered or 
threatened under section 4(e) solely because of a similarity in 
appearance.
    Section 4(e) of the Act provides that the Secretary may, by 
regulation of commerce or taking, and to the extent he deems advisable, 
treat any species as an endangered species or threatened species even 
though it is not listed pursuant to section 4 of the Act if the 
Secretary finds three criteria are met that: (A) such species so 
closely resembles in appearance, at the point in question, a species 
which has been listed pursuant to the Act that enforcement personnel 
would have substantial difficulty in attempting to differentiate 
between the listed and unlisted species; (B) the effect of this 
substantial difficulty is an additional threat to an endangered or 
threatened species; and (C) such treatment of an unlisted species will 
substantially facilitate the enforcement and further the policy of the 
Act (16 U.S.C. 1533(e)). The Act provides the Service discretion in 
determining both when and how to apply section 4(e). However, as 
discussed below, there are several ways in which the statutory language 
demonstrates that Congress did not intend for the 4(e) authority to 
apply to species that warrant listing under section 4(a). Moreover, the 
legislative history further underscores this limitation on 4(e) 
authority.
    First, the plain language of the Act provides for no circumstances 
in which a species that meets the definition of a threatened species 
under section 4(a) would also meet the criteria at section 4(e)(A)-(C) 
for being ``treated'' as an endangered species. Treating a species as 
endangered under section 4(e), when that species separately warrants 
protection in its own right as a threatened species under section 4(a), 
would circumvent the protections intended for species that qualify for 
listing under section 4(a) and would never satisfy the requirements 
under 4(e)(C) to further the policy of the Act (i.e., section 2(b)-(c) 
of the Act). Sections 4(a)-(c) establish the primary mechanism for 
determining whether species meet the definition of an endangered 
species or a threatened species. For species that meet the definition 
of an endangered species or a threatened species based on the factors 
and standards set out in sections 4(a)-(b), section 4(c)(l) provides 
the mandatory requirement that the Secretary list those species 
according to the definition they meet. Nowhere does section 4(a)-(c) 
include a requirement to consider a species' similarity of appearance 
to an already listed species when making a listing determination, nor 
does 4(e) either address, alter, or amend any of the provisions in 
sections 4(a)-(c) or characterize the similarity-of-appearance 
authority it provides as mandatory.
    Moreover, for species that meet the definition of a threatened 
species under section 4(a), treating the species instead as endangered 
under section 4(e) would not provide any greater protections than the 
species would otherwise receive as a threatened species listed under 
section 4(a). In most cases, doing so would actually provide species 
with fewer protections than listing them as threatened species under 
section 4(a). This is because species treated as endangered or 
threatened under section 4(e) do not receive the protections of the Act 
provided to species listed under section 4(a), such as the designation 
of critical habitat, consultation requirements for Federal agencies 
under section 7, and the recovery planning provisions under section 
4(f).
    Section 4(e) specifies that the authority to ``treat'' any 
similarity-of-appearance species as an endangered or threatened species 
is to be exercised ``by regulation of commerce or taking, and to the 
extent [the Secretary] deems advisable.'' Therefore, all applicable 
prohibitions and exceptions for species treated under section 4(e) of 
the Act as endangered or threatened based on their similarity of 
appearance to a species listed under section 4(a) are set forth by 
regulation, such as in a species-specific rule, and are determined with 
the goal of furthering the conservation of the species listed under 
section 4(a) that the 4(e) species resembles. The Act does not 
differentiate how the Service should regulate commerce or taking of 
species treated as endangered based on similarity of appearance as 
compared to those treated as threatened based on similarity of 
appearance. In either situation, the Service issues regulations that it 
deems are advisable relating to commerce or taking of the species. 
Moreover, there is no requirement that those regulations for a species 
being treated as endangered under section 4(e) provide greater 
protections than the regulations for treating a species as threatened 
under section 4(e). For all these reasons, treating a species as 
endangered under section 4(e), when that species separately warrants 
protection as a threatened species under section 4(a), will not 
facilitate the enforcement or further the policy of the Act.
    Second, the court's interpretation in Friends of Animals that the 
section 4(e) ``similarity of appearance'' provision requires the 
Service to consider treating a species as endangered when it is listed 
as threatened under section 4(a) is in direct conflict with the plain 
language of section 4 of the Act. Section 4(e) explicitly limits its 
applicability to unlisted species, authorizing the Secretary to treat 
any species as an endangered species or threatened species ``even 
though it is not listed pursuant to section 4 of this Act.'' Similarly, 
the third criterion for treating a species as endangered or threatened 
pursuant to section 4(e) requires that ``such treatment of an unlisted 
species will substantially facilitate the enforcement and further the 
policy of this Act'' (sections 4(e) and 4(e)(C) (emphases added)). 
Thus, our authority to treat species as endangered species or 
threatened species due to similarity of appearance is limited to 
species that are otherwise ``unlisted'' or ``not listed'' and does not 
extend to species that are listed under section 4(a).
    If Congress had intended for section 4(e) to apply to any species 
that warrant listing as endangered species or threatened species under 
section 4(a),

[[Page 11677]]

Congress would have no need to include the terms ``unlisted'' and ``not 
listed'' in section 4(e). Congress also used the latter of those 
terms--``not listed''--in section 9 of the Act. In both section 4(e) 
and section 9, those terms are used as a necessary precondition for any 
species to qualify for the statutory provision at issue. Under section 
4(e), only a species that is ``not listed'' may be considered for 
treatment as an endangered or threatened species based on similarity of 
appearance to a listed species. Under section 9, the term ``not 
listed'' is a precondition for the limited exceptions to import or 
export prohibitions (i.e., ``It is unlawful [to import or export] . . . 
fish or wildlife (other than shellfish and fishery products which (i) 
are not listed pursuant to section 4 of this Act as endangered species 
or threatened species, and . . .)'' (section 9(d)(1)(A), with similar 
language in sections 9(e) and (f)).
    This conclusion is also supported by the Act's legislative history. 
Multiple congressional reports--from both houses of Congress--made this 
clear. For example, when the Act was enacted in 1973, the Senate Report 
described how the statute deals with the problem presented by two 
species that are so similar in appearance that people without 
specialized training cannot distinguish between them: ``If one species 
is listed under section 4, but the other is not, the Secretary may 
treat the unlisted species as an endangered or threatened species if 
such treatment will substantially facilitate the enforcement and 
further the policy of this Act'' (S. Rep. No. 93-307, at 9 (1973) 
(emphasis added)); see also H. Rep. No. 93-412, at 12 (1973), and H.R. 
Rep. 100-928, at 20 (1988)). In light of the clear statutory language 
and legislative history, while the Service has discretion in when to 
treat an ``unlisted'' or ``not listed'' species as an endangered 
species or threatened species under section 4(e), this discretion does 
not extend to species that warrant listing under section 4(a), like the 
northern DPS (16 U.S.C. 1533(a); 1532 (6), (20)).
    In accordance with the statutory language and legislative history, 
our regulations, guidance, and longstanding practice all provide for 
treatment of species as endangered or threatened under section 4(e) 
only when the species is not listed under section 4(a). Our regulations 
provide that ``whenever a species which is not Endangered or Threatened 
closely resembles an Endangered or Threatened species, such species may 
be treated as either Endangered or Threatened'' (50 CFR 17.50, emphasis 
added). These regulations have remained substantively unchanged since 
their promulgation in 1975 (although they were amended for other 
reasons at various times). Moreover, since the inception of section 
4(e), we have only ever considered invoking its authority for species 
that do not warrant listing under section 4(a), and we have never 
evaluated a section 4(a)-listed species under section 4(e). For 
example, in invoking section 4(e) to treat the American alligator as 
listed in 1975, we first delisted three populations of alligators that 
had previously been listed as endangered species under section 4(a) and 
then decided to treat those unlisted populations as listed under 
section 4(e) (40 FR 44412, Sept. 26, 1975).
    In light of the above points, the Service does not evaluate whether 
to treat a species as endangered under section 4(e) of the Act if that 
species separately meets the definition of a threatened species under 
section 4(a). Therefore, because we found that the northern DPS of the 
southern subspecies of scarlet macaw meets the definition of a 
threatened species under section 4(a), we did not evaluate whether it 
should be treated as an endangered species under section 4(e).
    However, even if the Act did give us the authority to evaluate 
whether the northern DPS of the southern subspecies of macaw should be 
treated as an endangered species under section 4(e), we would not find 
that the northern DPS met the criteria for such treatment identified in 
section 4(e)(A)-(C). As explained above, and further discussed below, 
treating the northern DPS as endangered under section 4(e) of the Act 
rather than actually listing it as a threatened species under section 
4(a) would not provide any additional protections for either the 
northern DPS or the northern subspecies, meaning such treatment would 
not facilitate the enforcement or further the policy of the Act.
    This conclusion is further supported by the court's ruling in 
Friends of Animals upholding our treatment of the southern DPS as a 
threatened (rather than endangered) species pursuant to section 4(e) of 
the Act. We found it was appropriate to treat the southern DPS of the 
southern subspecies as threatened, not endangered, under section 4(e) 
``because the 4(d) rule . . . provide[d] adequate protections for'' the 
section 4(a)-listed scarlet macaws that the southern DPS resembled, and 
the treatment of the southern DPS as threatened would substantially 
facilitate law enforcement actions to protect and conserve those 4(a)-
listed macaws, including the endangered northern subspecies (84 FR 
6278, February 26, 2019). The court in Friends of Animals upheld that 
determination, finding, ``[h]aving reviewed the whole record--and 
cognizant of the significant discretion that Congress vested in the 
Service to make similarity-of-appearance listing decisions, see 16 
U.S.C. 1533(e)--the Court finds that the Service satisfactorily 
discharged its duty to articulate a `rational connection between the 
facts found and the choice made' to list the Southern DPS as 
threatened'' and not endangered as plaintiff argued.
    The same reasoning would apply when evaluating whether to treat the 
northern DPS as endangered under section 4(e), rather than listing it 
as a threatened species under section 4(a). Specifically, the 4(d) rule 
for the northern DPS also provides adequate protections for the 
northern subspecies. Additionally, treating the southern DPS as 
threatened under section 4(e) and listing the northern DPS as a 
threatened species under section 4(a) will facilitate law enforcement 
actions to protect and conserve both the northern DPS and the northern 
subspecies. As such, the Service would have no basis for extending 
additional protections to the northern DPS if it were treated as 
endangered based on similarity of appearance to the northern 
subspecies. Therefore, we would not treat the northern DPS as 
endangered under section 4(e) rather than list it as a threatened 
species under section 4(a) because so doing would not facilitate 
enforcement or further the policy of the Act for the conservation of 
either the northern DPS of the southern subspecies of scarlet macaw (A. 
m. macao) or the northern subspecies of scarlet macaw (A. m. 
cyanoptera).
