Erolia
''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. 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. Taxonomy The genus ''Calidris'' was introduced in 1804 by the German naturalist Blasius Merrem with the red knot as the type species. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The genus contain 24 species: * Great knot, ''Calidris tenuirostris'' * Red knot, ''Calidris canutus'' * Surfbird, ''Calidris ...

Semipalmated Sandpiper
The semipalmated sandpiper (''Calidris pusilla'') is a very small shorebird. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''pusilla'' is Latin for "very small". 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''. Description It is a small sandpiper, long and weighing around . Wingspan ranges from . Adults have black legs and a short, stout, straight dark bill. The body is dark grey-brown on top and white underneath. The head and neck are tinged light grey-brown. This bird can be difficult to distinguish from other similar tiny shorebirds, in particular the western sandpiper; these are known collectively as "peeps" or " stints". Breeding and habitat Their breeding habitat is the southern tundra in Canada and Alaska near water. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Sandpiper
The rock sandpiper (''Calidris ptilocnemis'') is a small shorebird in the sandpiper family Scolopacidae. This is a hardy sandpiper that breeds in the arctic and subarctic regions of Alaska and the Chukotka Peninsula, Chukotka and Kamchatka Peninsulas. It is closely related to the purple sandpiper that breeds in arctic regions of northeast Canada and the northwest Palearctic. Taxonomy The rock sandpiper was species description, formally described in 1873 by the American ornithologist Elliott Coues and given the binomial name ''Tringa ptilocnemis''. It was formerly placed in the genus ''Erolia'', but is now placed with 23 other sandpipers in the genus ''Calidris'' that was introduced in 1804 by the German naturalist Blasius Merrem. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific epithet ''ptilocnemis'' combines the Ancient Greek ''ptilon'' meaning "feather" with ''knēmē'' meaning "leg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baird's Sandpiper
Baird's sandpiper (''Calidris bairdii'') is a small shorebird. It is among those calidrids which were formerly included in the genus ''Erolia'', which was wiktionary:subsume, subsumed into the genus ''Calidris'' in 1973. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The English name and specific ''bairdii'' commemorate Spencer Fullerton Baird, 19th-century naturalist and assistant secretary of the Smithsonian Institution. Description Adults have black legs and a short, straight, thin dark bill. They are dark brown on top and mainly white underneath with a black patch on the rump. The head and breast are light brown with dark streaks. In winter plumage, this species is paler brownish gray above. This bird can be difficult to distinguish from other similar tiny shorebirds; these are known collectively as "peeps" or "stints". One of the best identification features is the long wings, which extend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple Sandpiper
The purple sandpiper (''Calidris maritima'') is a small shorebird in the sandpiper family Scolopacidae. This is a hardy sandpiper that breeds in the arctic and subarctic regions of Eurasia and North America and winters further south on the Atlantic coast. Taxonomy The purple sandpiper was formally described in 1764 by the Danish zoologist Morten Thrane Brünnich and given the binomial name ''Tringa maratina''. This species was formerly placed in the genus ''Erolia'', but is now placed with 23 other sandpipers in the genus ''Calidris'' that was introduced in 1804 by the German naturalist Blasius Merrem. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific epithet ''maritima'' is from Latin and means "of the sea", from ''mare'', "sea". The purple sandpiper is treated as monotypic: no subspecies are recognised. Within the genus ''Calidris'' the purple sandpiper is sister to the rock sandp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Stint
The little stint (''Calidris minuta'' 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. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''minuta'' is Latin for "small. Description Its small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It can be distinguished from these in all plumages by its combination of a fine bill tip, unwebbed toes and long primary projection. The call is a sharp "stit". The breeding adult has an orange wash to the breast, a white throat and a strong white V on its back. In winter plumage identification is difficult. Juveniles have pale crown stripes and a pinkish breast. An apparent hybrid between this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanderling
The sanderling (''Calidris alba'') is a small wading bird. The name derives from Old English ''sand-yrðling'', "sand-ploughman". The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific, ''alba'', is Latin for "white". It is a circumpolar Arctic breeder, and is a long-distance migrant, wintering south to South America, South 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 sandpipers in appearance, which has led to the suggestion that it should be placed into a monotypic genus ''Crocethia''. A more recent review (Thomas ''et al.'', 2004) 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. This bird is similar in size to a dunlin, but stouter, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunlin
The dunlin (''Calidris alpina'') is a small wader in the genus '' Calidris''. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from ''dun'', "dull brown", with the suffix ''-ling'', meaning a person or thing with the given quality. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in western Europe are short-distance migrants largely staying on western and southern European and northwest African coasts; those breeding in far northern Europe and Asia are long-distance migrants, wintering south to Africa, southeast and west 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. Taxonomy The dunlin was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa alpina''. Linnaeus spec ...

Red-necked Stint
The red-necked stint (''Calidris ruficollis'') is a small migratory wader. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''ruficollis'' is from Latin ''rufus'', "red" and ''collum'', "neck". Description These birds are among the smallest of waders, very similar to the little stint, ''Calidris minuta'', with which they were once considered conspecific. The red-necked stint's small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It measures in length, in wingspan and in body mass. It can be distinguished from the western sandpiper and the semipalmated sandpiper in all plumages by its combination of a fine bill tip, unwebbed toes, and longer primary projection. The breeding adult has an unstreaked orange breast, bordered with dark markings below, and a white V on its back. In winter plumage identif ...

Long-toed Stint
The long-toed stint (''Calidris subminuta'') is a small wader. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''subminuta'' is from Latin ''sub'', "near to" and ''minuta'', "small" from its similarity to the little stint, ''Calidris minuta''. It breeds across Palearctic, northern Asia and is strongly bird migration, migratory, wintering in south and south east Asia and Australasia. It occurs in western Europe only as a very rare vagrant. This bird has yellowish legs and a short thin dark bill. Breeding adults are a rich brown with darker feather centres above and white underneath. They have a light line above the eye and a brown crown. In winter, long-toed stints are grey above. The juveniles are brightly patterned above with rufous colouration and white mantle stripes. This bird can be difficult to distinguish from other similar tiny waders which are known collectively as "peeps" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temminck's Stint
Temminck's stint (''Calidris temminckii'') is a small wader. This bird's common name and Latin binomial commemorate the Dutch naturalist Coenraad Jacob Temminck. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. Temminck's stint is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies. Description These birds are very small waders, at length. They are similar in size to the little stint (''Calidris minuta'') but shorter legged and longer winged. The legs are yellow and the outer tail feathers white, in contrast to little stint's dark legs and grey outer tail feathers. This is a rather drab wader, with mainly plain brown upperparts and head, and underparts white apart from a darker breast. The breeding adult has some brighter rufous mantle feathers to relieve the generally undistinguished appearance. In winter plumage, the genera ...

Curlew Sandpiper
The curlew sandpiper (''Calidris ferruginea'') is a small wader that breeds on the tundra of Arctic Siberia. It is strongly bird migration, migratory, wintering mainly in Africa, but also in south and southeast Asia and in Australia and New Zealand. It is a Vagrancy (biology), vagrant to North America. Taxonomy The curlew sandpiper was species description, formally described in 1763 by the Danish author Erik Pontoppidan under the binomial name ''Tringa ferrugineus''. It is now placed with 23 other sandpipers in the genus ''Calidris'' that was introduced in 1804 by the German naturalist Blasius Merrem. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''ferruginea'' is from Latin ''ferrugo, ferruginis'', "iron rust" referring to its colour in breeding plumage. The curlew sandpiper is treated as monotypic: no subspecies are recognised. Within the genus ''Calidris'' the curlew sandpiper i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stilt Sandpiper
The stilt sandpiper (''Calidris himantopus'') is a small shorebird. The scientific name is from Ancient Greek. The genus name ''kalidris'' or ''skalidris'' is a term used by Aristotle for some grey-coloured waterside birds. The specific ''himantopus'' means "strap foot" or "thong foot", and also refers to the stilt. Taxonomy This sandpiper 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 be separated with it in ''Erolia''. Range & habitat The stilt sandpiper breeds in the open arctic tundra of North America. It is a long-distance migrant, wintering mainly in northern South America. It occurs as a rare vagrant in western Europe, Japan and northern Australia. Breedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
