Did You Know?

There are several birds of prey that are called kestrels. Kestrels are noted for hovering while hunting their prey of large insects, birds, and small mammals. Kestrels are mainly Old World birds, but one species, the American kestrel, often called sparrow hawk in the US, is common throughout North and South America. It is about 12 in (30 cm) long, white or yellowish below, and reddish brown and slate-gray above, with colorful markings on the head. The common kestrel of the Old World is larger and less colorful.
