Peregrine Falcons are native to Labrador; winter migrant to Newfoundland.
Peregrines prefer coastal and inland cliffs and adjacent country, especially in the area of seabird colonies. They prefer open country, particularly shores and marshes where shorebirds and waterfowl are plentiful. They will occasionally occupy large cities.
Peregrines are distributed throughout Canada; they winter in South America.
Species preys almost exclusively on birds, from small songbirds to ducks. They will also feed on small mammals such as bats and voles, and occasionally on amphibians and even insects.
Peregrines have few enemies. However, the impact on their food chain by pesticides such as DDT has resulted in a sharp decline in their numbers, which subsequently resulted in their being considered "endangered" in most parts of the world in recent years. (See Notes).
The peregrine will live 12-18 years in the wild.
