Peregrine Falcon (Eastern Population)
The peregrine falcon is an endangered species. Endangered species are
animals and plants that are in danger of becoming extinct. Threatened
species are animals and plants that are likely to become endangered in
the foreseeable future. Identifying, protecting, and restoring
endangered and threatened species is the primary objective of the U.S.
Fish and Wildlife Service's endangered species program.
What is the Peregrine Falcon?
- Scientific Name
- Falco peregrinus
- Appearance
- Peregrine falcons are crow-sized birds of prey with long, pointed
wings and a long tail. These birds have bluish backs, wings and flanks
barred with black, a white face with a black stripe on each side, and
large, dark eyes.
- Reproduction
- Peregrines first breed when two or three years old. They nest mainly
on high cliffs, although some birds nest on bridges or ledges of
skyscrapers in large cities. The female lays 3-5 eggs and after 32-34
days, the eggs hatch. Young leave the nest when they are 35-40 days old.
- Feeding Habits
- Peregrines usually hunt their prey in flight. Peregrine falcons eat
small to medium-sized birds. Those living in urban areas eat pigeons,
starlings, and other birds.
- Range
- Three subspecies of the peregrine falcon
occur in North America. The Peale's peregrine falcon (Falco peregrinus
pealei) is resident year-round on the northwest Pacific coast. The arctic
peregrine falcon (F. p. tundrius) nests in the tundra regions of Alaska,
Canada, and Greenland. The American peregrine falcon (F. p. anatum) breeds
throughout much of the remainder of North America, from the subarctic
boreal forest to Mexico.
- Populations
- The eastern population of the
American peregrine falcon is found in North America from the Great Plains
eastward, including adjacent portions of Canada. Within the Great Plains,
eastern peregrine falcons have begun nesting in urban settings while the
related prairie falcon continues nesting on the plains.
