Habitat

Usually nests near small ponds and lakes, sedge meadows, creeks; in cover 1-2 ft high, within 46 m of water (NatureServe 2007b). Nests around semi-permanent (< 1 ha) waterbodies with emergent vegetation, but will also nest in sparse shrub patches (Austin et al. 1998). In interior Alaska, broods use >1 ha semi-permanent and permanent wetlands characterized by cattail and sedge (van Horn 1991).
