Taxonomic Comments
Inland and coastal populations along mid-Atlantic coast show marked morphological and life history differences; M. G. nigrescens regarded as a well-marked subspecies by Greenberg and Droege (1990). Greenberg et al. (1998) examined mitochondrial DNA differentiation between nigrescens, georgiana, and epicrypta and found low levels of genetic variation and no evidence of geographic structure.

BREEDING: Mackenzie to northern Saskatchewan and Labrador, south to British Columbia, central Saskatchewan, Dakotas, eastern Nebraska, central Ohio, and Delaware. NON-BREEDING: eastern Nebraska, Iowa, Great Lakes region, and southern New England south to southeastern Arizona, southern Texas, Gulf Coast, southern Florida.
Ecology & Habitat

Habitat

BREEDING: Marshes, wet brushy fields, meadows, lakeshores, stream borders, swamps, pine barrens shrub-sedge bogs; also brackish marshes along mid-Atlantic coast (Greenberg and Droege 1990). Nests in tussock of grass, sedge, or in low bush, commonly over water. NON-BREEDING: In migration and winter also in weedy fields, brush, thickets, scrub, and forest edge (AOU 1998).

Reproduction

Clutch size 2-6 (usually 4-5 in most areas). Usually 2 broods per year. Incubation 12-15 days, by female. Young leave nest at 9-13 days.
