Success of the Eastern Peregrine Recovery Plan in recent years has helped restore populations of the peregrine falcon. Peregrine falcons are found on all continents except Antarctica. There are 17 subspecies, but only 3 are found in North America. In level flight, peregrines can fly about 60 mph. The adult peregrine is a crow-sized bird with a 36 to 44 inch wingspan.
Young birds have darker, brownish plumage.
Their breast is marked with vertical brown streaking. Peregrines may live to be 12 to 15 years old. This means that approximately 6 of every 10 falcons hatched will die in its first year of life. Peregrines typically nest on ledges of rock cliffs. However, falcons have been able to adapt to use tall buildings.
