They eat pigeons, starlings, blackbirds, ducks, flickers, jays and doves, which they catch in the air. Peregrines can dive at speeds of over 200 MPH and in level flight, they can achieve speeds of about 60 MPH, making them nature's fastest bird.
Peregrines are about the size and weight of crows.
The female peregrine typically lays three to five eggs in early spring. She and her mate share the 33-day incubation duties, which include turning the eggs regularly. Baby peregrines are called eyases. At hatch time, they are scantly covered with white down, weigh about two ounces, and have a small white bump on their beaks. It gradually disappears as the bird matures.
