Habitat

Cliff-faces for breeding, hunts over cultivated land and grassland, marshes and wetlands, beaches and the sea. Also increasingly using urban areas to nest/breed on buildings.

Behaviour

Flight

Takes prey on ground and in the air using height advantage to gain speed. Often employs a high speed steep dive where reported speeds exceed 200kph. The impact of this dive can kill prey outright. Also pursues prey such as Feral Pigeon/Rock Dove in flight using speed from a dive and rapid jinking manoeuvering.

Diet

The diet includes birds, such as doves, waterfowl and songbirds, occasionally hunt small mammals, including bats, rats, voles and rabbits. Insects and reptiles make up a relatively small proportion of their diet. Peregrine Falcons also eat their own chicks when starving.

Breeding

A scrape on a cliff ledge is made and 3-4 eggs are laid. The females incubate the eggs for 29-32 days. Chicks fledge 35-42 days after hatching. Is increasingly being reported using urban high-rise buildings and churches for nest/breeding sites to prey on Feral Pigeon.
