About the species
The Peregrine Falcon has a slate-blue back and long, pointed wings, set off by pale underparts crossed with fine dark bars. A black cap and bold cheek stripe frame its pale throat, while black wingtips show clearly when it banks overhead. Its narrow tail ends in a dark band and a white tip.
Outside the breeding season it is usually quiet, but near the nest gives a sharp, repeated "kya-kya-kya." It watches from a high perch or circles above open ground, then folds its wings and dives at prey, striking it in midair with its feet. During courtship, the male passes prey to the female in midair, and she turns upside down to take it.
It nests on cliffs and ledges, but in cities also uses tall buildings and bridges, where pigeons provide much of its food. It hunts in open air, taking prey on the wing; many populations stay year-round in mild regions, while those breeding in the Arctic migrate south for winter.
Where to find
-
In cities where the Peregrine Falcon nests on tall buildings or bridges, watch for a fast stoop at pigeons.
-
Over open marshes at dawn or dusk, look for a searching flight followed by a sudden dive at passing prey.
-
Along a rocky waterside, scan the ledges beneath overhangs — these sheltered spots are used for nesting.
