Do peregrine falcons build nests?
Most birds build nests made of sticks and soft natural fiber material in which their eggs are incubated. Peregrine falcons lay their eggs in “scrapes,” which are shallow indentations they scratch out with their talons in the soft earth on the floor of the nest ledge. Peregrine falcons typically nest on ledges and in small shallow caves located high on cliff walls. They have been known to use the abandoned nests of other birds, and on the north slope of Alaska, commonly nest on the ground.
