Calidris is a genus of Arctic-breeding, strongly migratory wading birds in the family Scolopacidae. These birds form huge mixed flocks on coasts and estuaries in winter. Migratory shorebirds are shown to have declined in reproductive traits because of temporal changes of their breeding seasons.[1] They are the typical "sandpipers", small to medium-sized, long-winged and relatively short-billed.

Their bills have sensitive tips which contain numerous corpuscles of Herbst. This enables the birds to locate buried prey items, which they typically seek with restless running and probing.[2]

Taxonomy

The genus Calidris was introduced in 1804 by the German naturalist Blasius Merrem with the red knot as the type species.[3][4] The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds.[5]

Many of the species have been treated under other generic names at various times in the past, but these treatments leave Calidris polyphyletic;[6][7] synonyms are in brackets in the list below.

The genus contain 24 species:[8]

The following species-level cladogram is based on a molecular phylogenetic study by David Černý and Rossy Natale that was published in 2022. Some of the nodes are only weakly supported by the sequence data.[9] Script error: No such module "Clade".
