Common kestrel

The common kestrel ("Falco tinnunculus") is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. It is also known as the 'European kestrel', 'Eurasian kestrel', or 'Old World kestrel'. The bird lives all over Europe, Asia, and Africa.
In Britain, where no other brown falcon occurs, it is generally just called 'the kestrel'.
Description.
Kestrels are 32–39 cm (13–15 in) from head to tail. Their wings are 65–82 cm (26–32 in) when spread out. Females are larger. They are small compared with other birds of prey, but larger than most songbirds. Like the other "Falco" species, they have long wings and a long tail.
Their feathers are mainly light brown with black spots on the top and buff with narrow blackish streaks on the underside.
Food and feeding.
When hunting, kestrels hover about 10–20 m (c.30–70 ft) above the ground. They can see the slightest movement. They can see small prey from a distance. Once they see the prey, the bird makes a short, steep dive. Kestrels eat almost any mouse-sized mammals like voles. They also eat shrews and true mice. Small birds are also eaten, mostly in the summer when young birds are born. The bird also eats spiders and beetles when it finds them.
