With regulations on pesticides, coupled with the protection and reintroduction of the birds, the peregrine has been slowly making a comeback. Peregrines historically nested on remote cliff sites throughout the Appalachians. However, they now find suitable habitat on urban buildings and other large structures. Peregrine falcons are the fastest flying birds of prey, with diving speeds of more than 200 miles per hour. Adult peregrines have wing spans of up to four feet and may be recognized by dark, sharply pointed wings and a long, narrow tail.
Peregrines have black heads, with white throats and breasts.
The young Atlanta peregrines will leave the nest to fly and hunt around the downtown area, making them vulnerable to crashing into windows and landing in the street.
