Formal Taxonomy
Animalia - Craniata - Aves - Passeriformes - Troglodytidae - Cistothorus - of eastern North America (Eastern Marsh-Wren) (Kroodsma 1989, AOU 1998). As yet not known if differences in song and plumage types are correlated, or if marsh wrens care about the song difference and what this means in terms of gene exchange (DeBenedictis, 1990, Birding 22:98-100).

Locally Migrant

Food Comments
Eats mainly insects and other invertebrates.
Reproduction Comments
Clutch size is 3-10 (commonly 5-6). Two broods per year, sometimes 3. Incubation, by female, lasts 12-16 days. Young leave nest at 11-16 days but are still fed. Males in most populations are polygynous (Leonard and Picman 1987).
Ecology Comments
Adults may destroy eggs and young of conspecifics and of other marsh-nesting passerines (see Leonard and Picman 1987). May be excluded from areas of marsh by yellow-headed blackbird (Leonard and Picman 1986). Territory size small, generally less than 0.2 hectares (Verner 1965, Verner and Engelsen 1970, Kale 1965).
