![]() from COSEWIC and The Birds of Manitoba (p. For more information, Peregrine Falcon Recovery Project (Manitoba) As of 2001, 103 captive-breed falcons have been released in Manitoba. Breeding pairs have been established in Winnipeg and in Brandon. Never common breeders in Manitoba, they have been reintroduced. the home range: the extended, non-defended area in which peregrines hunt for additional food and which can extend to 27 km from the nest peregrines prefer open habitats such as wetlands, tundra, savanna, sea coasts and mountain meadows, but will also hunt over open forest.The nesting territory: the area defended around the nest prevents other pairs from nesting within 1 km or more, ensuring adequate food for all nesting pairs and their young the density of nests tends to be related to food availability The nest site: nests are usually scrapes made on cliff ledges on steep cliffs, usually near wetlands - including artificial cliffs such as quarries and buildings Their habitat requirements can be divided into three components: And though urbanization and other land uses have had a significant impact on some areas where they feed, Peregrine Falcons can usually modify their diet based on the prey species present in a given area. Structures built by humans in both rural and urban areas provide Peregrine Falcons with potential nesting sites. Suitable nesting sites are usually dispersed, but can be common locally in some areas. They usually nest alone on cliff ledges or crevices, preferably 50 to 200 meters in height, but sometimes on the ledges of tall buildings or bridges, always near good foraging areas. The Merlin is also much smaller (31 cm (12 in) in length), lacks the large black wedge that occurs on the face, and has a more boldly barred tail than the Peregrine Falcon.Peregrine Falcons are found in various types of habitats, from Arctic tundra to coastal areas and from prairies to urban centres. ![]() The American Kestrel is much smaller than the Peregrine Falcon (27 cm (10.5 in) in length) and has a rusty-colored back and tail. In the Southeast, the two species most similar to the Peregrine Falcon are the American Kestrel and the Merlin. Since the banning of DDT and reintroduction projects, this species is well on its way to recovery. The Peregrine Falcon's decline was attributed to pesticides, specifically DDT, either by causing death directly or by reducing reproductive success to near zero. However, this species is still listed as Endangered by every southeastern state. Ten years later, the Arctic Peregrine Falcon was removed from the list and in 1999 the American Peregrine Falcon was removed. In 1984, the American Peregrine Falcon subspecies was Federally listed as Endangered, and the Arctic Peregrine Falcon subspecies was listed as Federally Threatened. In the Southeast the Peregrine Falcon is most common on the coasts and in Florida during the winter. Within the United States, this species is most common in the West during the breeding season and in coastal areas during the winter. It can reach speeds of up to 200 miles per hour while diving to strike its prey. Cities have also provided a good source of food, the Rock Dove (pigeon).The Peregrine Falcon captures its prey on the wing, usually striking it with its talons and knocking the bird out of the air or killing it immediately. The Peregrine Falcon eats a wide variety of birds, including waterfowl, doves, shorebirds, and passerines. Since its reintroduction into the eastern United States, however, the Peregrine Falcon has colonized many urban areas because of increased nesting sites (and nesting ledges being created on buildings). In more wild habitat, the Peregrine Falcon frequents open areas like marshes, fields, swamps, and tidal areas. Juvenile birds are dependent on their parents for care for several months after they hatch. The young are semi-altricial and stay in the nest for 35-42 days after hatching. The incubating female is fed by the male. ![]() The female lays 2-6 (usually 3-4) eggs that she incubates for 29-32 days. The nest is usually a scrape lined with fine materials. Nesting habitat is highly variable, including more traditional cliffs or trees, and man-made structures like towers and the ledges of tall buildings. The breeding season probably begins in March and extends into May. Peregrine Falcons are able to breed at 3 years of age. Most of head dark black or brown, with a dark wedge below eye buff color on throat, extending to upper chest and partially up each side of the neck belly, feathers covering upper legs, and tail are barred back and wings dark legs yellow. They live mostly along mountain ranges, river valleys and coastlines and are increasingly being found in large cities.
