Ecology and Life History
Migration
false - false - true - Begins migrating northward in late February, passing through U.S. and Canada in April-May; arrives in breeding areas in Beaufort Sea area in late May or early June. Migrates mainly through interior North America, Middle America, and northern South America, and in fall (uncommon in spring) through eastern North America and West Indies (AOU 1983). Northern Alaska: adults begin southward migration in late June, juveniles depart late August-early September; most still in North America in September-October are juveniles (Hayman et al. 1986). Most common in Puerto Rico and Virgin Islands in fall, August-early November (Raffaele 1983). Passes through northern South America early August to mid-November (Hilty and Brown 1986). Amazonia apparently is an important migration route (Stotz et al. 1992).

Food Comments
Feeds on many insects in addition to crustaceans, some arachnids, seeds, and worms. Food picked from among grass, or picked or probed from soft mud.
Reproduction Comments
Breeding begins late May to early June (Harrison 1978). Female incubates 4 eggs for 21-23 days (Terres 1980) (also reported as usually 20 days). Nestlings precocial. Most males leaves breeding areas before eggs hatch (Hayman et al. 1986). Young tended by female; young begin flying about 21 days after hatching, fledge in late July or early August in northern Alaska. More than 10 nests per sq km in many areas in northern Alaska; often wide annual fluctuations in breeding density (see Johnson and Herter 1989).
Ecology Comments
May be seen singly or in flocks (sometimes several thousand in Puerto Rico) (Raffaele 1983). Some individuals may defend feeding territories.

Global Range
H - >2,500,000 square km (greater than 1,000,000 square miles) - H - BREEDING: western and northern Alaska, northern Yukon, northern Mackenzie, and Banks, Victoria, Bathurst, Devon, northern Baffin, and Southampton islands south to western Alaska, central Mackenzie, southeastern Keewatin, and south coast of Hudson Bay; and along Arctic coast of central and eastern Siberia. NON-BREEDING: southern South America from Peru, Bolivia, and southern Brazil south to central Chile and southern Argentina (AOU 1983). Siberian birds probably winter in southeastern Australia and New Zealand. Common fall migrant and rare winter visitor in Hawaii (Pratt et al. 1987). MIGRATION: through interior North America, Middle America, and northern South America. In fall (and uncommonly in spring) through eastern North America and West Indies (AOU 1983).
