Peregrine Falcon

The Peregrine Falcon, known scientifically as Falco peregrinus, is a large falcon roughly the size of a crow. It boasts a blue-grey back, barred white underparts, and a distinct black head. This raptor is celebrated for its incredible speed, often exceeding 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest member of the animal kingdom. The highest recorded speed for a Peregrine Falcon is an astonishing 389 km/h (242 mph).

Identification Tips

Adult Peregrine Falcons have a blue-black to slate grey back with indistinct darker barring. Their underparts are white to rusty, barred with thin, clean bands of dark brown or black. The tail is similarly colored but with thin, clean bars. A notable feature is the black "moustache" that sharply contrasts with the pale sides of the neck and white throat. The cere and feet are yellow, while the beak and claws are black. Juveniles are browner with streaked underparts and a pale bluish cere.

Habitat

Peregrine Falcons are found along mountain ranges, river valleys, coastlines, and increasingly in urban settings, where they utilize tall buildings as nesting sites.

Distribution

The Peregrine Falcon's breeding range is extensive, spanning from the Arctic tundra to the tropics. It is nearly ubiquitous across the globe, save for extreme polar regions, very high mountains, and most tropical rainforests.

Behaviour

Peregrine Falcons are known for their high-speed hunting stoops. They are territorial during the breeding season, with nesting pairs spaced widely apart. They are adaptable and can thrive in urban environments, taking advantage of the abundance of prey such as pigeons and ducks.

Song & Calls

The Peregrine Falcon's vocalizations include a series of loud, sharp "kek-kek-kek" calls, particularly during nesting or when intruders approach the nest.

Breeding

Peregrine Falcons reach sexual maturity between one and three years of age and mate for life. They nest in a scrape, usually on cliff edges or, in urban areas, on tall structures. They lay a clutch of three to four eggs, which are incubated for about a month.

Similar Species

The Peregrine Falcon can be confused with other falcon species, but its size, distinctive stoop, and plumage patterns are usually distinguishing features.

Diet and Feeding

The diet of the Peregrine Falcon consists almost exclusively of medium-sized birds, but it may also hunt small mammals, reptiles, or insects. Urban Peregrines often feed on pigeons and other city birds.

Conservation Status

The Peregrine Falcon was once endangered due to pesticide use but has recovered remarkably well following the ban on DDT and concerted conservation efforts. It is currently listed as Least Concern by the IUCN.
