LIFE HISTORY

PHYSICAL DESCRIPTION: has same features as American peregrine (anatum subspecies) but is smaller, paler in color, whiter on breast, and has narrower black moustache marks on side of face *488,685*; medium-sized, pointed wings, swift-flying falcon with prominent black and white underparts streaked and barred with black; immatures are brown above and have leaner streaking on underparts than adults *761*; REPRODUCTION: species arrival on breeding grounds is synchronized with the arrival of their major prey species *761*; breeding season: middle of May into June; incubation period: about 33 days; incubation and brooding primarily by female, who sits more closely than females in more southern latitudes *761*; clutch size: average for Arctic birds is 3 eggs *761,685*; average fledging success on the Colville River, Alaska, was 1.4 young per nest *761*; breeding behavior: females are dominant over males *761*; food brought to nest by male for female during incubation and for female to feed to young once hatching occurs *761*; BEHAVIOR: territoriality: very territorial during breeding season; area immediately near nesting cliff is defended most intensely against all other predatory birds; area farther out is defended only over food *761*; migration: species is highly migratory *762*; majority of migrants seen along Atlantic coast appear to be from the Arctic subspecies *771*; they migrate for the most part along the Atlantic coast, but some go through the U.S. interior; the Atlantic coastal flight includes those from western Greenland *761,763,764*; they winter in the coastal areas of the southern U.S., the West Indies, and Central and South America *762*; in a peregrine banding effort on Maryland-Virginia coast beaches, 83-84% of the population banded in a 10 year period were immatures *764*; nest site: cliff nests are most typical and are on a ledge or in a hole usually under an overhang and mostly along rivers, lakes, or marshes where prey is abundant *761,488* nest itself is usually a scrape in earth or gravel with no lining *761*; ORIGIN: native *760,404,407*; POPULATION PARAMETERS: decline in species population of Arctic Canada and Alaska detected in early 1970's; cause was attributed to residues of organo-chlorines in tissues and eggs, affecting normal reproduction *761,771*; despite banning of DDT use in U.S. in 1972, it is still widely used in Central and South America where many of the Arctic peregrines and their migratory prey winter; this situation is a difficult one to solve *488,765,766,767,770*; the status of species has apparently improved since the mid-70's for the Fish and Wildlife Service has proposed reclassifying the species from endangered to threatened; levels of DDT and its metabolites in females have been decreasing and number of young produced annually increasing *768*; AQUATIC/TERRESTRIAL ASSOCIATIONS: former rough-legged hawk nests are sometimes used as nest sites *761*; in addition to man, predators on eggs and young include timber wolf, red fox, Arctic ground squirrel, and golden eagle, but none of them have a significant effect *761*; gyrfalcons apparently can affect peregrine density and distribution by keeping them from the larger river cliffs *761* REFERENCES FOR LIFE HISTORY- 760, 404, 761, 488, 762, 407, 763, 764, 765, 766, 767, 768, 685, 770 and 771 Life History - 1
