Oct. 5th, 2011 finding by the U.S. Fish and Wildlife Service that the cactus ferruginous pygmy-owl (Glaucidium ridgwayi cactorum) does not warrant protection from the Endangered Species Act.

"We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum) as threatened or endangered and to designate critical habitat under the Endangered Species Act of 1973, as amended (Act). Additionally, the petition requested that we recognize and list a western subspecies of the cactus ferruginous pygmy-owl (Glaucidium ridgwayi cactorum), or, alternatively, two potential distinct population segment (DPS) configurations. After review of all available scientific and commercial information, we find that Glaucidium ridgwayi cactorum is not a valid taxon, and, therefore, not a listable entity under the Act. Additionally, using the currently accepted taxonomic classification of the pygmy-owl (Glaucidium brasilianum cactorum), we find that listing the pygmy-owl is not warranted at this time throughout all or a significant portion of its range, including the petitioned and other potential DPS configurations. However, we ask the public to submit to us at any time any new information concerning the taxonomy or status of the pygmy- owl, as well as any new information on the threats to the pygmy-owl or its habitat."
