Habitat
Breeds on coastal lowland tundra. On Amchitka Island (and likely other low-lying, nonvolcanic Aleutian Islands), nests in Empetrum-Cladonia tundra, sedge-meadow tundra found in lakes and pond regions with little relief, and riparian meadow characterized by dense lush stands of herbaceous vegetation . In early autumn, birds reported in heath tundra of Amchitka Island (Gill et al. 2002).
