The Peregrine Falcon (Falco peregrinus), also known as the Peregrine, and historically as the Duck Hawk in North America,[3] is a widespread bird of prey in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head and "moustache". As is typical of bird-eating raptors, Peregrine Falcons are sexually dimorphic, females being considerably larger than males.
