Falco Peregrinus

he Peregrine Falcon (Falco peregrinus), also known simply as the Peregrine,[2] and historically as the "Duck Hawk" in North America,[3] is a cosmopolitan bird of prey in the family Falconidae. It is a large, crow-sized falcon, with a blue-gray back, barred white underparts, and a black head and "moustache". It can reach speeds over 322 km/h (200 mph) in a dive, making it the fastest animal in the world.[4] As is common with bird-eating raptors, the female is much bigger than the male.[5][6] Experts recognize 17–19 subspecies, which vary in appearance and range; there is disagreement over whether the distinctive Barbary Falcon is a subspecies or a distinct species.

The Peregrine's breeding range includes land regions from the Arctic tundra to the Tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread bird of prey.[7] Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations.

While its diet consists almost exclusively of medium-sized birds, the Peregrine will occasionally hunt small mammals, small reptiles or even insects. It reaches sexual maturity at one year, and mates for life. It nests in a scrape, normally on cliff edges or, in recent times, on tall human-made structures.[8] The Peregrine Falcon became an endangered species in many areas due to the use of pesticides, especially DDT. Since the ban on DDT from the beginning of the 1970s onwards, the populations recovered, supported by large scale protection of nesting places and releases to the wild.[9]
