Kestrel

 

(Cerchneis tinnunculus), a bird of prey of the family Falconidae. The body is 31–38 cm long and weighs 160–240 g. The females are larger than the males. The back and tail of the female are reddish yellow with dark transverse stripes; the males have dark speckles above and a gray tail with a dark tip.

The kestrel is found in Europe, Asia (except the Far North), and Africa. It inhabits all zones except the tundra, living both in mountains and on the plains. In the Pamir Mountains the bird has been observed at elevations reaching 4,000 m. In the northern part of its range, the kestrel is a migratory bird. It nests in trees, using the old nests of other birds, on rocky cliffs, and in abandoned buildings. A clutch contains four or five eggs, which are incubated by both parents for 28 days. The birds leave the nest within a month. Kestrels feed on small rodents, insects, lizards, and small birds. They are useful in exterminating rodents.

Abstract: To evaluate the toxicity of short-term high doses of meloxicam in American kestrels [Falco sparverius), 32 male captive-born, 1- to 4-year-old American kestrels were randomly assigned to 4 groups: 3 groups treated with meloxicam (n = 9 per group) and a control group (n = 5).
