{"abstract":"We, the U.S. Fish and Wildlife Service (Service), propose to list the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum), a subspecies found in Mexico, southern Arizona, and southern Texas, as a threatened species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the cactus ferruginous pygmy-owl. After a review of the best available scientific and commercial information, we find that listing the subspecies is warranted. Accordingly, we propose to list the cactus ferruginous pygmy-owl as a threatened species with a rule issued under section 4(d) of the Act (\"4(d) rule\"). If we finalize this rule as proposed, it would add this subspecies to the List of Endangered and Threatened Wildlife and extend the Act's protections to the subspecies. The finalization of this rule as proposed would include the issuance of a 4(d) rule. Designation of critical habitat was found to be prudent, but not determinable at this time. We also are notifying the public that we have scheduled an informational meeting followed by a public hearing on the proposed rule.","action":"Proposed rule.","agencies":[{"raw_name":"DEPARTMENT OF THE INTERIOR","name":"Interior Department","id":253,"url":"https://www.federalregister.gov/agencies/interior-department","json_url":"https://www.federalregister.gov/api/v1/agencies/253","parent_id":null,"slug":"interior-department"},{"raw_name":"Fish and Wildlife Service","name":"Fish and Wildlife Service","id":197,"url":"https://www.federalregister.gov/agencies/fish-and-wildlife-service","json_url":"https://www.federalregister.gov/api/v1/agencies/197","parent_id":253,"slug":"fish-and-wildlife-service"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2021/12/22/2021-27516.html","cfr_references":[{"chapter":null,"citation_url":null,"part":17,"title":50}],"citation":"86 FR 72547","comment_url":null,"comments_close_on":"2022-02-22","correction_of":null,"corrections":[],"dates":"We will accept comments received or postmarked on or before February 22, 2022.
