Common kestrel
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.
