HABITAT: Found on arctic continental coastal belts and marginally within the subarctic just beyond treeline. Inhabits grassy and sedgy tundra, with or without scattered low woody vegetation and usually near shallow fresh water. In migration and winter, prefers grassy margins of shallow, muddy freshwater pools and, occasionally saltwater habitats. Associates freely with other shorebirds, including the larger plovers.
SPECIAL HABITAT REQUIREMENTS: Grassy tundra and wet meadows.
NEST: Nests in a shallow depression in a tuft of grass or in moss, on dry or moist ground, usually near freshwater.
FOOD: Feeds in open unvegetated tracts of mud, as well as patches surrounded by tundra. Eats flies, beetles, small crustaceans and mollusks, marine worms, spiders, and seeds of aquatic plants.
