Ecology & Life History
General Description: A dark henlike bird with a blackish head and neck, slate body (paler in juveniles), and a frontal shield that usually is small and maroon or dark brown (may become bulbous at peak of breeding season; a few have a white frontal shield); undertail coverts white on the sides, black in the middle; white trailing edge on wings; whitish bill; large feet with lobed toes (NGS 1983).
Global Reproduction Comments: Clutch size is 6-22 (most often 8-12 in North America; average about 6 in Hawaii). Incubation lasts 23-24 days, by both sexes. Young are tended by both parents, though brood may be divided between them. First flies probably at 7-8 weeks. Usually renests if first clutch is destroyed (Condor 95:273-281); easily able to produce many additional eggs (Auk 109:407-421).
Global Ecology Comments: Nonbreeding: often in groups (Stiles and Skutch 1989).

Global Migration Comments: Generally arrives in northern breeding areas March-May, departs by October-November (in portion of range in which it is migratory, especially northern inland areas) (Bent 1926). Migrants arrive in Costa Rica generally by October, most depart by end of April (Stiles and Skutch 1989).

Global Habitat Comments: Freshwater lakes, ponds, marshes, and larger rivers, wintering also on brackish estuaries and bays. Also on land bordering these habitats. Calm open water with plenty of algae and other aquatic vegetation (Stiles and Skutch 1989). Typically builds floating nest among marsh plants in 30-100 cm of water (Harrison 1979). In south-central Saskatchewn, nesting habitat and reproductive effort and success were greatly reduced during drought (Sutherland 1991).
Food Habits: Carnivore: Adult, Immature
Granivore: Adult, Immature
Herbivore: Adult, Immature
Invertivore: Adult, Immature
Piscivore: Adult, Immature
Global Food Habits Comments: Eats seeds, roots, and other plant material, insects, snails, small fishes, tadpoles, and other small organism; feeds on land and in water (at surface, by tipping up, and by diving) (Terres 1980).

Global Range Comment: BREEDS: east-central Alaska (casual), southern Yukon east through central Manitoba to Prince Edward Island, south locally to southern Baja California, Gulf Coast, Florida, Nicaragua and northwestern Costa Rica, West Indies (not Puerto Rico or Virgin Islands). WINTERS: Pacific coast, and north to the southwestern U.S., lower Ohio Valley, and Maryland, south throughout Middle America, southeastern U.S., and West Indies to Panama and probably Colombia. RESIDENT in Hawaii and in South America in the Andes from Colombia south to western Bolivia, northern Chile, and northwestern Argentina. (AOU 1983). Birds from North America apparently are regularly present as nonbreeding visitors in Hawaii (Pratt 1987).
