Range, habitat and subspecies
Peregrine Falcons live mostly along mountain ranges, river valleys, and coastlines and increasingly, in cities. They are widespread throughout the entire world and are found on all continents except Antarctica.
There are many subspecies of Peregrine Falcons, including:
* Falco Peregrinus tundrius breeds in the Arctic tundra of North America but is migratory and travels as far as South America.
* F.p. pealie is found in the Pacific Northwest of North America, and is non-migratory.
* F.p. anatum is mostly found in the Rocky Mountains. Although it used to be common throughout eastern North America, and is currently being re-introduced in the region, it remains uncommon in much of its former range. Most mature anatums, except those that breed in more northern areas, winter in their breeding range.
Peregrines in mild winter regions are usually permanent residents. Other populations migrate; for instance, birds from Alaska, northern Canada and Greenland migrate to Central and South America. Similarly, many birds from northern Eurasia move further south or to coasts in winter, but in milder areas, some birds, especially adult males, will remain on the breeding territory. Migrating birds may travel far out over open ocean.
Breeding
Courtship displays include spectacular aerobatic flight and dives by the male and aerial pursuits. A pair may mate for life. These birds aggressively defend the nesting area.
The nest is a scrape or depression dug in gravel on a cliff ledge. Sometimes if no cliff is available, peregrines will nest in a tree cavity, an old stick nest, or even a tussock of grass on the tundra. These birds also nest on tall buildings in cities, which resemble their natural nesting sites. The female usually lays 3 to 5 eggs; the color ranges from reddish white to mottled brown.
If a Peregrine Falcon lives through its first year, it can live up to 10 years. However, most young birds do not survive their first year.
