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 decline in reproductive traits because of temporal changes of their breeding seasons.[2] 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.[3]
Taxonomy
editThe genus Calidris was introduced in 1804 by the German naturalist Blasius Merrem with the red knot as the type species.[4][5] The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds.[6]
The genus contain 24 species:[7]
- Great knot, Calidris tenuirostris
- Red knot, Calidris canutus
- Surfbird, Calidris virgata
- Ruff, Calidris pugnax
- Broad-billed sandpiper, Calidris falcinellus
- Sharp-tailed sandpiper, Calidris acuminata
- Stilt sandpiper, Calidris himantopus
- Curlew sandpiper, Calidris ferruginea
- Temminck's stint, Calidris temminckii
- Long-toed stint, Calidris subminuta
- Spoon-billed sandpiper, Calidris pygmaea
- Red-necked stint, Calidris ruficollis
- Sanderling, Calidris alba
- Dunlin, Calidris alpina
- Rock sandpiper, Calidris ptilocnemis
- Purple sandpiper, Calidris maritima
- Baird's sandpiper, Calidris bairdii
- Little stint, Calidris minuta
- Least sandpiper, Calidris minutilla
- White-rumped sandpiper, Calidris fuscicollis
- Buff-breasted sandpiper, Calidris subruficollis
- Pectoral sandpiper, Calidris melanotos
- Semipalmated sandpiper, Calidris pusilla
