Taxonomic Comments
Formerly considered conspecific with Old World G. gallinago (AOU 1998) because of overall morphological similarities, but separated by Banks et al. (2002) on the basis of differences in winnowing display sounds associated with differences in the tail feathers (Thonen 1969, Tuck 1972, Miller 1996). South American and African forms are now generally treated as distinct species as well (Banks et al. 2002). Has been placed in the genus Capella by some authors, but that name is regarded as invalid by most authorities (Banks and Browning 1995).

BREEDING: northern Alaska east through southern Keewatin to Labrador, south to southern Alaska, central California, eastern Arizona, New Mexico (probably), Colorado, Nebraska, Iowa, Illinois, northern Indiana, Ohio, West Virginia, Pennsylvania, New Jersey, New England, and Maritime Provinces. NON-BREEDING: southern Alaska (rarely), southern British Columbia, Washington, Oregon, Utah, central U.S., and Virginia south through Middle America and the West Indies to Colombia, Venezuela, Surinam, and Ecuador; casual or accidental in Hawaii, Bermuda, Greenland and Scotland (AOU 1998, Banks et al. 2002).
Ecology & Habitat

Habitat

ALL SEASONS: Wet grassy or marshy areas from tundra to temperate lowlands and hilly regions. NON-BREEDING: wet meadows, flooded fields, bogs, swamps, moorlands, and marshy banks of rivers and lakes. BREEDING: Nests in tussock of vegetation in or at edge of marsh, wet meadow, or bog.

Ecology

Nonbreeding: forages singly or in loose groups, usually roosts in flocks (Stiles and Skutch 1989).

Reproduction

Clutch size usually 4. Incubation usually 17-20 days, by female. Young leave nest soon after hatching, tended by both parents in 2 separate groups, capable of sustained flight at about 20 days.
