Habitat
Breeds in riparian areas, such as densely vegetated wetlands, shallow lakes and ponds, sedge-grass-bulrush meadows, estuarine salt marshes, marshy borders of rivers, beaver ponds, sewage lagoons, roadsides, ditches, riparian scrub, permanent ponds in fields, wooded swamps, regenerating trembling aspen clearcuts (Phinney 1998), abandoned quarries, and similar habits dominated by emergent vegetation, including tall sedges, reedbeds, stands of cattails, sweetgale, and willow (Campbell et al. 2001). Has also been reported in drier habitats along the edges of agricultural lands, airport runways, tall grasses bordered by shrubs, and even in the undergrowth of a mixed forest of conifer and trembling aspen (Pojar 1993).
