Sanderling

Open encyclopedia reference

The sanderling (Calidris alba) is a small wading bird. It is a circumpolar Arctic breeder, being among the most extreme northern breeding birds in the world, nesting only on the coldest tundra, north of the 5°C July isotherm; in Europe, its southernmost breeding locality is Svalbard, where only a handful (5–15) pairs breed. It is a long-distance migrant, wintering south to South America, western and southern Europe, Africa, and Australia. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches. It is somewhat unlike other small sandpipers in appearance, in particular in lacking a hind toe, which has led to the suggestion that it should be placed into a monotypic genus Crocethia. More recent reviews indicate that the sanderling is a fairly typical "stint" or small sandpiper and should be retained along with the knots and other relatives in the genus Calidris. This bird is similar in size to a dunlin, but stouter, with a thick bill.
