The kestrel (Falco tinnunculus) or Windhover is a small British bird of the falcon family Falconidae. The kestrel has brown plumage that is lightly barred with black, while the head, neck and tail are bluish grey. The kestrel generally eats mice and insects, though they will sometimes take small birds and chickens. When hunting the kestrel hovers almost motionless before swooping down on its prey.
