This tiny bird is the smallest falcon in North America. Unlike many other raptors, the male and female are easily distinguished by color. The male bears light blue coloration on top of his wings. The female lacks the blue coloration on her wings and has brown on top instead.
Unlike many other falcons who are bird hunting specialists, the American kestrel is primarily an insect and rodent hunter. Like other falcons, kestrels have a “tomial tooth” on their beak to help them kill their prey. While the “tooth” is not really a tooth at all, it does work much like canines in predators who kill with a swift bite to the neck.
