common kestrel
Quick Summary
The common kestrel is a small bird of prey belonging to the genus Falco. These birds are known for their distinctive hunting technique of hovering in mid-air while searching for prey, which includes large insects, birds, and small mammals.12
While kestrels are primarily found in the Old World, the American kestrel (F. sparverius) is a notable exception, being common throughout North and South America. This species, sometimes referred to as a sparrow hawk in the U.S., measures about 12 inches (30 cm) in length. It displays sexual color dimorphism, with males being more colorful. The American kestrel is characterized by its white or yellowish underside, and reddish-brown and slate-gray upperparts, often featuring colorful markings on its head.12
The common kestrel (F. tinnunculus) of the Old World is slightly larger but less colorful than its American counterpart. It is the only kestrel species found in Britain, where it is also known as the "windhover" due to its habit of hovering against the wind.2
