Genus Calidris

Sharp-tailed Sandpiper - More recently, a review of new data has indicated that this bird should perhaps better be placed into the genus Philomachus - as P. acuminatus - which now contains only the ruff but if the Sharp-tailed Sandpiper is merged into it would need to accommodate the Broad-billed Sandpiper also .

Sanderling - It is somewhat unlike other sandpipers in appearance, which has led to the suggestion that it should be placed into a monotypic genus Crocethia. A more recent review indicates, however, that the sanderling is a fairly typical "stint" or small sandpiper and should be separated from the large knots with its closest relatives in a distinct genus.

Dunlin - The Dunlin, Calidris alpina, is a small wader, sometimes separated with the other "stints" in Erolia. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in northern Europe and Asia are long-distance migrants, wintering south to Africa and southeast Asia. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in Northern Alaska overwinter in Asia.

Baird's Sandpiper - The Baird's Sandpiper is a small shorebird. It is among those calidrids sometimes separated in Erolia.

Red Knot - The Red Knot, Calidris canutus , is a medium sized shorebird which breeds in tundra and the Arctic Cordillera in the far north of Canada, Europe, and Russia. It is a large member of the Calidris sandpipers, second only to the Great Knot. Six subspecies are recognised.

Curlew Sandpiper - The Curlew Sandpiper is a small wader that breeds on the tundra of Arctic Siberia. It is strongly migratory, wintering mainly in Africa, but also in south and southeast Asia and in Australasia. It is a vagrant to North America.

White-rumped Sandpiper - The White-rumped Sandpiper is a small shorebird.

Stilt Sandpiper - The Stilt Sandpiper, Calidris himantopus or Micropalama himantopus, is a small shorebird; it bears some resemblance to the smaller calidrid sandpipers or "stints". DNA sequence information is incapable of determining whether it should be placed in Calidris or in the monotypic genus Micropalama . It appears most closely allied with the Curlew Sandpiper, which is another aberrant species only tentatively placed in Calidris and could conceivably separated with it in Erolia.

Purple Sandpiper - The Purple Sandpiper, Calidris, Arquatella or Erolia maritima is a small shorebird.

Western Sandpiper - The Western Sandpiper, Calidris or Erolia mauri, is a small shorebird.

Pectoral Sandpiper - The Pectoral Sandpiper, "Calidris" melanotos, is a small wader. It is sometimes separated with the "stint" sandpipers in Erolia. This may or may not represent a good monophyletic group, depending on the placement of the phylogenetically enigmatic Curlew Sandpiper , the type species of Erolia. In any case, the genus name Ereunetes – formerly used for the Western Sandpiper and Semipalmated Sandpiper , which are also members of the stint clade – was established before Erolia.

Kleine Strandloper - The Little Stint, Calidris or Erolia minuta, is a very small wader. It breeds in arctic Europe and Asia, and is a long-distance migrant, wintering south to Africa and south Asia. It occasionally is a vagrant to North America and to Australia. It is gregarious in winter, sometimes forming large flocks with other Calidris waders, particularly Dunlin, on coastal mudflats or the edges of inland pools.

Least Sandpiper - The Least Sandpiper, Calidris or Erolia minutilla, is the smallest shorebird.

Rock sandpiper - The Rock Sandpiper is a small shorebird.

Semipalmated Sandpiper - The Semipalmated Sandpiper, Calidris pusilla, is a very small shorebird. It is sometimes separated with other "stints" in Erolia but although these apparently form a monophyletic group, the present species' old genus Ereunetes had been proposed before Erolia.

Rufous-necked Stint - The Red-necked Stint is a small migratory wader.

Long-toed stint - The Long-toed Stint, Calidris or Erolia subminuta, is a small wader bird. It breeds across northern Asia and is strongly migratory, wintering in south and south east Asia and Australasia. It occurs in western Europe only as a very rare vagrant.

Temminck's Stint - Temminck's Stint, Calidris or Erolia temminckii, is a small wader.

Great knot - Their breeding habitat is tundra in northeast Siberia. They nest on the ground laying about four eggs in a ground scrape. They are strongly migratory wintering on coasts in southern Asia through to Australia. This species forms enormous flocks in winter. It is a rare vagrant to western Europe.
