The Peregrine Falcon is a medium-sized raptor with blue-gray wings, brown backs, and buff undersides with brown spots. They have a hooked beak and strong talons to catch prey such as songbirds, ducks, and bats in mid-air. Peregrine falcons mate for life and nest on cliff ledges or man-made structures, where the female lays 3-4 eggs which both parents incubate for around a month.
