kestrel

/ˈkɛstrəl/

Other forms: kestrels

A kestrel is a small falcon that hovers high in the air before swooping down on its prey. Kestrels typically hunt for insects, rodents, and lizards.

In North America, a kestrel is distinguished from other falcons by its small size — it's about the same size as a blue jay or mourning dove. These colorful birds have rusty-brown, black, white, and blue plumage, and they're commonly seen hovering above an open field, wings beating, before diving to snatch a grasshopper or mouse. Experts aren't certain of the origin of kestrel, although some suspect a Latin source, crepitacillium, "small rattle," after their distinctive call.
