10,000 Birds
FEBRUARY 13, 2013
Peregrine Falcon ( Falco peregrinus ) at Delevan NWR (click on photos for full sized images). I’m sure most of you know that the Peregrine Falcon became an endangered species because of the use of organochlorine pesticides, especially DDT, during the 1950′s, 60′s, and 70′s. Love those talons!
