The calidrids and their allies are a group of Arctic breeding, strongly migratory wading birds. These birds form huge mixed flocks on coasts and estuaries in winter. They are the typical "peeps", small to medium-sized, long-winged and relatively short-billed.

Their bills have sensitive tips which enable them to locate buried prey items, which they typically seek with restless running and probing.
