The Peregrine Falcon (Falco peregrinus), also known simply as the Peregrine, is the fastest flying bird, capable of diving at a speed of 350km/h (217mph). Peregrines have previously been rare, but they are now widespread and fairly common.
The Peregrine has white underparts with much black streaking, their wings and back are gray and they have a black stripe around their eyes and head. The Peregrine keeps its wings very close when in flight, and its yellow legs are tucked backwards. The males are much smaller than the females.
Peregrines are birds found throughout most of America, Australia, Asia, Europe and Africa, excluding the Sahara Desert.
The Peregrine Falcon lives alone or in couples and is a migratory bird.
The Peregrine often nests on cliff ledges or in abandoned crow nests. They lay 3 or 4 eggs which are creamy white with brown and red markings. Though there were previous eggshell problems with a DDT outbreak in California, most eggs are now healthy in the wild.
The Peregrine Falcon feeds exclusively on birds, wich are caught in mid-air. The Falcon dives from above and hits the bird to stun it, then kills it by breaking its neck with its bill. The Peregrine Falcon usually hunts birds from the size of a sparrow to the size of a grouse or duck (and sometimes eats smaller raptors, such as kestrels or sparrowhawks), however, Peregrines have been known to attack birds much bigger than that, like pelicans, if not to hunt them, to mob them.
The Peregrine Falcon is often aggressive towards raptors or corvids larger than it. It is seen chasing eagles, buzzards and kites away from its territory. This behaviour is called "mobbing". Corvids like crows, magpies and jackdaws mob peregrine falcons.
