In northern Alaska, breeds in both low-lying marshy tundra and drier tussock-heath tundra, near the coast and inland to foothills and passes of the Brooks Range (Maher 1970, 1974). Nest usually places in low-lying marshy tundra, with sedge meadows, low-center polygons, and sphagnum or frost mounds, often near a lake, river, or coast (Brandt 1943, Parmelee et al. 1967, Maher 1974, Taylor 1974, Portenko 1989). In coastal tundra of northern Yukon, this species is found at lakes (Salter et al. 1980) and in late summer, it is found in riparian vegetation dominated by shrubby willows (Maher 1974).
