Common Kestrel is one of the commonest birds of prey, often seen hovering above the country while searching for prey. Adult male has blue-grey head with black moustache. The upperparts are reddish-chestnut, heavily spotted with drop-like spots. Rump and tail are bluish grey. Tail shows black subterminal bar. Tail feathers are finely white-tipped. On the wings, primary and secondary flight feathers are blackish.
Chin is whitish. Underparts are yellowish-brown, streaked and speckled black. Undertail feathers are narrowly barred and show black subterminal band.
Common Kestrel frequents numerous kinds of open or slightly wooded areas with tall grass and low shrubs such as grasslands, steppes, cultivated fields, wetlands with some vegetation. This species is also present in villages, towns and big cities, nesting on monuments.
It is found from sea-level to tree-line in mountains, with sites for perching, roosting and hunting.
Common Kestrel feeds primarily on small mammals (voles, mice, shrews). It is able to catch some passerines in open areas but small numbers. However, it takes young birds when possible, and also lizards and insects.
Common Kestrel hunts by performing low flight, but also from perch. When the prey is detected, it swoops down onto the prey in rapid short flight. This bird performs very typical hovering flight at height between 10 and 40 metres, carefully searching for prey on the ground.
It may sometimes catch some flying insects, birds or bats on the wing.
Common Kestrel is an efficient hunter feeding mainly on small mammals (voles, mice) which are about 90% of the diet. They are caught by hovering flight above the ground, waiting for the right moment before to swoop down onto the prey. It also consumes some passerines, lizards and insects.
