The peregrine falcon is perhaps best identified by the black mask of feathers that covers its face. They have dark bluish-grey heads and backs. Their throats and under parts are white, dispersed with black and brown feathers. Peregrines also have hooked bills, large feet and sharp talons to help them attack and eat their prey. The peregrine falcon prefers nesting in open areas that are best-suited for the falcon’s direct pursuit style of hunting. As a result, the peregrine favours habitats that are in open non-forested areas, including marshes, sea coasts, river valleys and tundra. Peregrines traditionally nest on cliffs but on occasion they’ve been found nesting in trees and on flat ground.
