The Peregrine Falcon is a beautiful raptor built for speed. They catch medium sized birds, including waterfowl, in the air with swift, spectacular dives called stoops.
The population of Peregrine Falcons was significantly reduced by pesticides during the mid 1900's. After controls of pesticides were initiated, Peregrines were reintroduced in temperate areas throughout the United States with success. The result has been the recovery of Arctic nesting populations as well.
