Above: Prairie Falcon (Falco mexicanus) near Larkspur, Colorado. Although the Prairie Falcon looks similar to the Peregrine Falcon, the facial "whiskers" on the Prairie Falcon are much more slender facial markings on the Peregrine Falcon. The bird has dark armpits which indicate it is a Prairie Falcon.
