Habitat and Ecology

Habitat and Ecology
The species breeds in marshy, swampy areas in lowland moss and shrub tundra (Johnsgard 1981, Flintet al.1984, del Hoyoet al.1996) near wet river valleys (Johnsgard 1981), lakes and sedge bogs (Flintet al.1984), as well as on swampy heathlands in the willow and birch zone near the Arctic treeline (Johnsgard 1981), in open larchLarixspp. woodland close to water (del Hoyoet al.1996), and occasionally on open bogs in the extreme north of the coniferous forest zone (Johnsgard 1981).The nest is a depression positioned on a dry elevated site (del Hoyoet al.1996) such as a tundra ridge (Johnsgard 1981) or hummock (Flintet al.1984), often between clumps of grass (del Hoyoet al.1996) or under a thicket (Flintet al.1984).On passage the species may frequent inland wetlands (Haymanet al.1986), sandy beaches with pinePinusspp. stands, swampy lowlands near lakes (Flintet al.1984) and short-grass meadows, but during the winter it is more common in intertidal areas along muddy coastlines, estuaries, inlets, mangrove-fringed lagoons and sheltered bays (del Hoyoet al.1996) with tidal mudflats or sandbars (Johnsgard 1981).

When breeding the species feeds on insects, annelid worms, molluscsand occasionally seeds and berries (del Hoyoet al.1996).In intertidal areas the species's diet consists of annelids (e.g.Nereisspp. andArenicolaspp.), bivalves and crustaceans, although it will also take cranefly larvae and earthworms on grasslands and occasionally larval amphibians (tadpoles) and small fish (del Hoyoet al.1996).This species is a full long-distance migrant (del Hoyo et al. 1996).
