Habitat

Usually seen in large flocks on ocean beaches.

Vegetation: coastal sand beaches and mudflats • Sensitivity to Disturbance: Medium

Typically found in a lake at a mean distance from sea level of 45 meters (148 feet).[1]

Ecology: Behaviour This species is a full long-distance migrant that travels mainly via offshore and coastal routes using a number of favoured stopover sites1. It breeds from June to mid-July in solitary pairs1, departing the breeding grounds between mid-July and early-September2. The species usually occurs in small flocks on migration3 although it may aggregate into larger flocks at stopover sites2, and in winter it forages in small to very large flocks1. Habitat Breeding The species breeds in the high Arctic on barren, stony tundra with well-drained ridges1, 3, gentle slopes or level alluvial plains supporting scattered vegetation of willow Salix spp. , Dryas spp. and saxifrage Saxifraga spp. usually less than 200 m above sea-level3. Non-breeding On passage the species may occur on inland freshwater or saline lakes1 but it is largely coastal during the winter, inhabiting open sandy beaches exposed to the sea , the outer reaches of estuaries, rocky and muddy shores , mudflats1 and coral reefs4. Diet Breeding When breeding the species takes insects (especially adult and larval Diptera, Coleoptera and Lepidoptera) as well as spiders and crustaceans1. On arrival on the breeding grounds the species may also complement its diet with plant matter (e.g. seeds, saxifrage buds, moss and algae)1 before invertebrate prey becomes available3. Non-breeding During the winter its diet consists of small molluscs , crustaceans, polychaete worms and adult, larval and pupal insects (e.g. Diptera, Coleoptera, Lepidoptera, Hemiptera and Hymenoptera), as well as occasionally fish and carrion1. Breeding site The nest is a shallow depression on the bare earth1 of stony well-drained ridges , gentle slope or level alluvial plains3. [2].
