Habitat
Breeds in a variety of wetlands, including freshwater and saltwater marshes, and lesser so upland habitats, including sedge meadows and crop fields. Also occurs in riparian areas and in open patches of forests (Nero 1984, Orians and Beletsky 1989, Searcy and Yasukawa 1995). In the northern part of its range, this species uses smaller ponds, and even muskeg habitats in spruce dominated forests (Campbell et al. 2001). Roosts during breeding season in dense cover primarily in wetlands (Meanley 1965, Weatherhead and Bider 1979). Usually nests near water (small ponds, lakes, beaver ponds), in cattails, rushes, sedges; occasionally in shrubs or trees (NatureServe 2007b). In Southeast Alaska, found in freshwater marshes and in sedges by beaver ponds (Johnson 2003).
