Description

The peregrine falcon is a medium sized bird of prey, measuring 35 to 50 cm in length and weighing 550 to 1,500 grams. The female peregrine falcon is considerably larger than the male. The wingspan is 80 to 120 cm. It has blue-grey back and barred white to rusty underparts. The head is black. A prominent black moustache is present along the cheeks. The wingtips are black. The tail is black, narrow and rounded, having a white band at the end. The sides of the neck and throat are pale or white. The cere and feet are yellow. The beak and claws are black. Their call is a loud series of 'kak, kak, kak' sound.

Habitat

The peregrine falcon inhabit extremely variable habitats. Their habitats includes mountain ranges, river valleys, coastlines and increasingly cities.

Feeding habits

The peregrine falcon species feed mainly on birds. They feed on medium-sized birds such as pigeons and doves, waterfowl, songbirds, waders, smaller birds of prey and game birds. These falcon species also feed on reptiles, small mammals and insects. During the stooping flight, the prey is typically struck with a clenched foot, stunned and captured in mid-air.

Breeding

The peregrine falcon breeding season varies according to their range. A falcon pair mates for life. They nest in a scrape of shallow hollow in the loose soil, normally on cliff edges. Large tree hollows are also used for nesting. The clutch size is commonly three to four eggs. The male bird also incubates the eggs. Both the parents take part in raising the chicks.

Distribution

Except extreme polar regions, these peregrine falcon species are found nearly everywhere on the Earth. They are entirely absent is New Zealand. The subspecies Falco peregrinus peregrinator is distributed in Indian subcontinent and southern China.

Movement Patterns

The peregrine falcons in temperate and Arctic zones are highly migratory. They migrate southwards in the winter.

Status and conservation

The peregrine falcon species have wide range of habitats and are considered least vulnerable. There was a sharp decline in the population due to the use of organochlorine pesticides, especially DDT. Hunting and egg collection also caused decline in the falcon population. With conservation and protection works and widespread restriction of DDT use, there is remarkable recovery in the population. The capture of wild falcons and fledglings for falconry and impacts with manmade structures are the main threats to the survival of these falcon species.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these falcon species and has listed them as of "Least Concern".
