HABITAT: Inhabits dry coastal and alpine tundra, particularly barren, exposed ridges, terrace banks, and raised beaches that are sparsely covered with low matted vegetation. Prefers sheltered places and frequents muddy, sandy, and grassy areas near water, including irrigated fields, shores of lakes and ponds, alpine tundra, and marshes. During migration, prefers inland to coastal habitats.
SPECIAL HABITAT REQUIREMENTS: Dry tundra.
NEST: Nests are in shallow depressions on the ground, usually in wind-blown and lichen-strewn areas with large patches of bare soil. Sometimes nests in grassy areas in a tuft of vegetation or among lichen-covered rocks.
FOOD: Forages by snatching food, primarily in dry areas or along wet edges of lakes and ponds. Eats small crustaceans, spiders, beetles and their larvae, gnats, craneflies, and other insects, moss, leaves and stems, and other plant parts.
