The Saker Falcon is a raptor of open grasslands preferably with some trees or cliffs. It often hunts by horizontal pursuit, rather than the Peregrine's stoop from a height, and feeds mainly on rodents and birds. In Europe, Ground Squirrels and feral pigeons are the most common prey items. This species usually builds no nest of its own, but lays its 3-6 eggs in an old stick nest in a tree which was previously used by other birds such as storks, ravens or buzzards. It also often nests on cliffs.
This bird is of course a captive bird and resides at that superb place -- the Hawk Conservacy Trust at Weyhill.
