of any new information on these species that has become available since the last reviews.

SUPPLEMENTARY INFORMATION:

We, the U.S. Fish and Wildlife Service (Service), are initiating 5-year status reviews under the Endangered Species Act of
1973, as amended (ESA; 16 U.S.C. 1531 et seq.) for the Eskimo curlew (Numenius borealis), spectacled eider (Somateria fischeri), and Southwest Alaska distinct population segment of the northern sea otter (Enhydra lutris kenyoni). A 5-year status review is based on the best scientific and commercial data available at the time of the review; therefore,
we are requesting submission of any such information that has become available since the last review for these species in
2021, particularly information on the status, threats, and recovery of the species (86 FR 40615).

Why do we conduct 5-year reviews?

Under the ESA, we maintain Lists of Endangered and Threatened Wildlife and Plants (which we collectively refer to as the List)
in title 50 of the Code of Federal Regulations (CFR) at 50 CFR 17.11 (for wildlife) and 50 CFR 17.12 (for plants). Section
4(c)(2)(A) of the ESA (16 U.S.C. 1533(c)(2)(A)) requires us to review each listed species' status at least once every 5 years.
Our regulation at 50 CFR 424.21 requires that we publish a notice in the
Federal Register
announcing that a species is under active review. For additional information about 5-year reviews, refer to our fact sheet
at https://www.fws.gov/project/five-year-status-reviews.

What information do we consider in our reviews?

A 5-year status review considers all new information available at the time of the review. In conducting these reviews, we
consider the best scientific and commercial data that have become available since the current listing determination or most
recent status review of each species, such as:

A. Species biology, including but not limited to population trends, distribution, abundance, demographics, and genetics;

B. Habitat conditions, including but not limited to amount, distribution, and suitability;

C. Conservation measures that have been implemented that benefit the species;

D. Threat status and trends in relation to the five listing factors (as defined in section 4(a)(1) of the ESA (16 U.S.C. 1533(a)(1)));
and

E. Other new information, data, or corrections, including but not limited to taxonomic or nomenclatural changes, identification
of erroneous information contained in the List, and improved analytical methods.

Any new information will be considered during the 5-year review and will also be useful in evaluating the ongoing recovery
programs for the species.

In the case of the Eskimo curlew, we concluded in our 2021 5-year review that the probability that the species remained extant
was extremely low based on the scarcity of recent sightings and the length of time that has passed since the last sighting
that was confirmed with physical evidence. We

  will therefore focus this 5-year review upon reported sightings or other recent information on the species' possible existence.
  Thus, we ask, in particular, for information on recent sightings, including indication as to whether corroborating evidence
  (such as photographs) is available for Eskimo curlew.
