Nests in mossy or wet grassy tundra, in lush vegetation near ponds, occasionally in drier areas with sparse vegetation or scattered bushes (NatureServe 2007b). In B.C., nests are built in areas away from taller woody vegetation on moss or sedge covered swampy ground or on hummocks if ground is extremely swampy. Young are reared in well vegetated, swampy grounds. Breeds from sea level to 1,200 m in B.C. (Campbell et al. 1990).
