The Red-footed Falcon (Falco vespertinus), formerly Western Red-footed Falcon, is a bird of prey. It belongs to the family Falconidae, the falcons. This bird is found in eastern Europe and Asia although its numbers are dwindling rapidly due to habitat loss and hunting.
It is a medium-small, long-winged species. The adult male is all blue-grey, except for his red undertail and legs; its underwings are uniformly grey. The female has a grey back and wings, orange head and underparts, and a white face with black eye stripe and moustaches.
Young birds are brown above and buff below with dark streaks, and a face pattern like the female. Red-footed Falcons are 28-34 centimetres (11-13½ in) in length with a wingspan of 65-75 centimetres (25½-29½ in).
This is a diurnal bird of open country with some trees, often near water. Its distinctive method of hunting is shared by the Common Kestrel. It regularly hovers, searching the ground below, then makes a short steep dive towards the target. The Red-footed Falcon’s main prey is large insects, but it will also take small mammals and birds.
This falcon is a colonial breeder, reusing the old nests of corvids, such as Rooks. It lays two to four eggs.
