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". [2]
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.
It is a small sandpiper, 15–18 cm (5.9-7.1 in) long and weighing around 18-51.5 g (0.6-1.8 oz). [3] Wingspan ranges from 13.8 to 14.6 in (35-37 cm). [4] 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".
Their breeding habitat is the southern tundra in Canada and Alaska near water. They nest on the ground. The male makes several shallow scrapes; the female chooses one and adds grass and other material to line the nest. The female lays 4 eggs; the male assists in incubation. After a few days, the female leaves the young with the male; the young feed themselves.
These birds forage on mudflats, picking up food by sight and feel (bill). They mainly eat aquatic insects and their larvae, spiders, snails, worms [5] and crustaceans. Semipalmated sandpipers rely heavily on horseshoe crab eggs during spring migration. [5] Females will also eat small mammal bones as an extra source of calcium during egg laying. [5]
They are long distance migrants and winter in coastal South America, with some going to the southern United States and the Caribbean. They migrate in flocks which can number in the hundreds of thousands, particularly in favoured feeding locations such as the Bay of Fundy and Delaware Bay. This species is a rare but regular vagrant to western Europe.
Although very numerous, these birds are highly dependent on a few key stopover habitats during their migration, notably Mary's Point and Johnson's Mills along Shepody Bay, an arm of the Bay of Fundy. [6] During the months of July and August, the Nature Conservancy of Canada runs an information center about these shorebirds in Johnson's Mills, New Brunswick. [7]
The upland sandpiper is a large sandpiper, closely related to the curlews. Older names are the upland plover and Bartram's sandpiper. In Louisiana, it is also colloquially known as the papabotte. It is the only member of the genus Bartramia. The genus name and the old common name Bartram's sandpiper commemorate the American naturalist William Bartram. The species name longicauda is from Latin longus, "long" and caudus, "tail". The name "Bartram's sandpiper" was made popular by Alexander Wilson, who was taught ornithology and natural history illustration by Bartram.
The sanderling 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".
A stint is one of several very small waders in the paraphyletic "Calidris" assemblage – often separated in Erolia – which in North America are known as peeps. They are scolopacid waders much similar in ecomorphology to their distant relatives, the charadriid plovers.
The dunlin is a small wader, formerly sometimes separated with the other "stints" in the genus Erolia. 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.
The little stint 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.
The least sandpiper is the smallest shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-colored waterside birds. The specific minutilla is Medieval Latin for "very small".
The purple sandpiper 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.
The western sandpiper is a 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 mauri commemorates Italian botanist Ernesto Mauri (1791–1836).
The white-rumped sandpiper is a small shorebird that breeds in the northern tundra of Canada and Alaska. This bird can be difficult to distinguish from other similar tiny shorebirds; these are known collectively as "peeps" or "stints".
Baird's sandpiper is a small shorebird. It is among those calidrids which were formerly included in the genus Erolia, which was 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.
The spotted sandpiper is a small shorebird. Together with its sister species the common sandpiper, it makes up the genus Actitis. They replace each other geographically; stray birds may settle down with breeders of the other species and hybridize.
The Hudsonian godwit is a large shorebird in the sandpiper family, Scolopacidae. The genus name Limosa is from Latin and means "muddy", from limus, "mud". The specific haemastica is from Ancient Greek and means "bloody". An 18th-century name for this bird was red-breasted godwit. The English term "godwit" was first recorded in about 1416–7 and is believed to imitate the bird's call.
The red-necked stint 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".
Temminck's stint 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.
The long-toed stint 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.
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.
The pectoral sandpiper is a small, migratory wader that breeds in North America and Asia, wintering in South America and Oceania. It eats small invertebrates. Its nest, a hole scraped in the ground and with a thick lining, is deep enough to protect its four eggs from the cool breezes of its breeding grounds. The pectoral sandpiper is 21 cm (8.3 in) long, with a wingspan of 46 cm (18 in).
The stilt sandpiper 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".
The buff-breasted sandpiper is a small shorebird. The species name subruficollis is from Latin subrufus, "reddish" and collis, "-necked/-throated". It is a calidrid sandpiper.
Mary's Point is a 12 square kilometres (4.6 sq mi) wetland in Albert County, New Brunswick, Canada. It is at the head of the Bay of Fundy, just outside the small community of Harvey and approximately 40 km (25 mi) south of Moncton. Designated a Ramsar wetland of international importance on May 24, 1982, it is also part of the Fundy biosphere reserve established in 2007, which also contains the Shepody Bay wetland. It was also the first Canadian site in the Western Hemisphere Shorebird Reserve, as part of the Bay of Fundy Hemisphere Shorebird Reserve. It is within the Shepody Bay National Wildlife Area, which is administered by the Canadian Wildlife Service.
