## Abstract

We, the U.S. Fish and Wildlife Service (Service), determine the eastern puma (=cougar) (Puma (=Felis) concolor couguar) to be extinct, based on the best available scientific and commercial information. This information shows no evidence of the existence of either an extant reproducing population or any individuals of the eastern puma subspecies; it also is highly unlikely that an eastern puma population could remain undetected since the last confirmed sighting in 1938. Therefore, under the authority of the Endangered Species Act of 1973 (Act), as amended, we remove this subspecies from the Federal List of Endangered and Threatened Wildlife.
