Peregrine falcons nest in high places like cliffs and tall human-made structures. The female lays 3-5 eggs and incubates them while the male hunts for food. In about 30 days, the eggs hatch and the chicks are helpless at first. Both parents care for the young by hunting and feeding them. After 4-6 weeks, the nestlings fledge but stay with their parents as juveniles to continue learning hunting skills until they can survive on their own.
