    Migration
    false - false - true - Most migrate northward through U.S. in late April and early May, arriving in nesting areas May-June. At Sable Island, Nova Scotia, begins to arrive by mid-May; females begin to migrate south by late June, males in early July, fledglings later. In British Columbia, southward adult migration was late June to early August, juvenile migration was late July to late September (Butler and Kaiser 1995, Wilson Bull. 107:413-422). Migrates through Costa Rica early August-October and early March-early May (Stiles and Skutch 1989). Arrives in northern South America by mid- to late July (juveniles first arrive mid-August), most depart by early April (Hilty and Brown 1986). May migrate from southeastern Canada directly to South America over western Atlantic (Hayman et al. 1986).

    Food Comments
    Eats small insects, crustaceans, mollusks, and worms obtained from surface of shallow water, mud, or ground, or by probing into mud (Terres 1980).
    Reproduction Comments
    Clutches are completed from late May tolate June. Clutch size is 4. Incubation, mostly by male (female at night), lasts about 19-22 days. Male attends young an average of about 3 weeks; female attendance averages about 1 week. Chicks fly strongly by 2 weeks (Miller 1985). Broods may amalgamate in habitat patches where families congregate after hatching (Can. J. Zool. 70:403).
    Ecology Comments
    Mortality of young high at Sable Island, mostly due to herring gull predation. Adults and fledglings tend to flock assortatively in late summer (Miller 1983). Nonbreeding: usually in small groups, singly, or from late winter onward in pairs (Stiles and Skutch 1989).
