The Peregrine Falcon has a body length of 34 to 58 cm (13-23 in) and a wingspan from 74 to 120 cm. The male and female have similar markings and plumage, but as in many birds of prey. Males weigh 330 to 1,000 g and the noticeably larger females weigh 513 to 1,500 g. The back and the long pointed wings of the adult are usually bluish black to slate grey with indistinct darker barring. The wingtips are black. The white to rusty underparts are barred with thin clean bands of dark brown or black. The tail, coloured like the back but with thin clean bars, is long, narrow, and rounded at the end with a black tip and a white band at the very end.
Habitat and Distribution
The Peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It in most areas, except extreme polar regions, very high mountains, and 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 raptor. It lives mostly along mountain ranges, river valleys, coastlines, and increasingly in cities. In mild-winter regions, it is usually a permanent resident.
The Peregrine Falcon feeds almost exclusively on medium-sized birds such as pigeons and doves, waterfowl, songbirds, and waders.
They nest in a scrape, normally on cliff edges. The female chooses a nest site, where she scrapes a shallow hollow in the loose soil, sand, gravel, or dead vegetation in which to lay eggs. No nest materials are added. Cliff nests are generally located under an overhang, on ledges with vegetation. Generally three to four eggs are laid. The eggs are white to buff with red or brown markings. They are incubated for 29 to 33 days, mainly by the female, with the male incubating at night.
