North America’s littlest falcon, the American Kestrel packs a predator’s fierce intensity into its small body. It's one of the most colorful of all raptors: the male’s slate-blue head and wings contrast elegantly with his rusty-red back and tail; the female has the same warm reddish on her wings, back, and tail.
Our smallest falcon, the kestrel is also the most familiar and widespread in North America. In open country it is commonly seen perched on roadside wires, or hovering low over a field on rapidly beating wings, waiting to pounce on a grasshopper.
