(Redirected from Barbary Falcon)
Includes Cape Verde Peregrine Falcon and Barbary Falcon
A large, powerful falcon, 34-50 cm (13Â½-19Â¾ in) long, 80-120 cm wingspan, and 550-1,500 g weight.
Adult male Slate grey to blackish above; buff barred darker below. Adult female similar but can be browner. Cere, legs and area around the eyes is yellow
The subspecies differ in size, mantle shade (mid-grey to nearly black), and head pattern, particularly the width of the moustachial stripe. In general, high latitude subspecies are larger and paler overall, and tropical subspecies smaller and nearly black above. F. p. peregrinator is strongly rusty-red on the breast and belly.
Almost worldwide - the most widely distributed bird of any, absent only from New Zealand and polar regions. See taxonomy, below, for more detail by subspecies.
F. p. pelegrinoides (sometimes together with F. p. babylonicus) has been separated as Barbary Falcon. However, at the moment only Gill and Donsker accept this split.
19 subspecies are recognised:
Cliff faces for breeding, hunts over cultivated land and grassland, marshes and wetlands, beaches and the sea. Also increasingly using urban areas to nest/breed on buildings.
Takes prey mainly in the air, using height advantage to gain speed. Typically employs a high speed steep dive (stoop), where reported speeds exceed 200 km/h. Uses the long, 'elasticated' hind toe to hit the bird without injuring itself; the impact of this often kills the prey outright. Also pursues prey such as Feral Pigeon/Rock Dove in flight using speed from a dive and rapid jinking manoeuvering. Only rarely takes prey on the ground or in water.
The diet includes a wide range of birds, such as doves, waterfowl and songbirds, including birds as large as Great Black-backed Gull and Brant Goose, up to 2 kg weight. Occasionally hunts small mammals, including bats, rats, voles and rabbits. Insects and reptiles make up a relatively small proportion of their diet. Exceptionally, Peregrine Falcons have been known to eat their own chicks when starving.
A scrape on a cliff ledge is made and 3-4 eggs are laid. The females incubate the eggs for 29-32 days. Chicks fledge 35-42 days after hatching. It is increasingly using urban high-rise buildings and churches for nest/breeding sites, to prey largely on Feral Pigeons.
Most of the subspecies are resident, but F. p. calidus and F. p. tundrius migrate long distances south to avoid the arctic winters experienced in their breeding ranges.
