The short-billed dowitcher (Limnodromus griseus), like its congener the long-billed dowitcher, is a medium-sized, stocky, long-billed shorebird in the family Scolopacidae.
It is an inhabitant of North America, Central America, the Caribbean, and northern South America. [2] It is strongly migratory; it completely vacates in breeding areas during the snow-bound months. [3] This species favors a variety of habitats including tundra in the north to ponds and mudflats in the south. It feeds on invertebrates often by rapidly probing its bill into mud in a sewing machine fashion. [4] It and the very similar long-billed dowitcher were considered one species until 1950. [5] Field identification of the two American Limnodromus remains difficult today. Distinguishing wintering or juvenile short-billed dowitchers from the long-billed species is very difficult and, even given examination their subtlety different body shapes, cannot always be isolated to a particular species. They differ most substantially in vocalizations. The names of American dowitchers are misleading, as there is much overlap in their bill lengths. [4] [5] Only a small percentage can be identified by this character alone. [5]
The short-billed dowitcher was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it in the genus Scolopax and coined the binomial name Scolopax grisea. [6] Gmelin based his description on the "brown snipe" from the coast of New York that had been described in 1785 by the English ornithologist John Latham and by the Welsh naturalist Thomas Pennant. [7] [8] The short-billed dowitcher is now placed in the genus Limnodromus that was introduced in 1833 by Prince Maximilian of Wied-Neuwied. [9] The genus name combines the Ancient Greek limnē meaning "marsh" with -dromos meaning "-racer" or "-runner". The specific griseus is Medieval Latin meaning "grey". [10] The English name "dowitcher" is from Iroquois and was first recorded in 1841. [11]
Three subspecies are recognised: [12]
The body of adults is dark brown on top and reddish underneath. The tail has a black and white barred pattern. The legs are a yellowish color.
The three subspecies have slight variations in appearance:
None of these combines the reddish belly and barred flanks of the breeding plumage long-billed dowitcher. The winter plumage is largely grey. This bird can range from 23 to 32 cm (9.1 to 12.6 in) in length, 46 to 56 cm (18 to 22 in) in wingspan and 73–155 g (2.6–5.5 oz) in body mass. [13]
The call of this bird is more mellow than that of the long-billed dowitcher, and is useful in identification, particularly of the difficult adult plumages.
The breeding habitat of the short-billed dowitcher includes bogs, tidal marshes, mudflats or forest clearings south of the tree line in northern North America. L. g. griseus breeds in northern Quebec; L. g. hendersoni breeds in north central Canada; L. g. caurinus breeds in southern Alaska and southern Yukon.
The birds migrate to the southern United States and as far south as Brazil. This bird is more likely to be seen near ocean coasts during migration than the long-billed dowitcher. This species occurs in western Europe only as an extremely rare vagrant.
These birds nest on the ground, usually near water. Their nests are shallow depressions in clumps of grass or moss, which are lined with fine grasses, twigs and leaves. They lay four, sometimes three, olive-buff to brown eggs. Incubation lasts for 21 days and is done by both sexes.
The downy juvenile birds leave the nest soon after hatching. Parental roles are not well known, but it is believed the female departs and leaves the male to tend the chicks, which find all their own food.
These birds forage by probing in shallow water or on wet mud. They mainly eat insects, mollusks, crustaceans and marine worms, but also eat some plant material.
The American wigeon, also known as the baldpate, is a species of dabbling duck found in North America. Formerly assigned to Anas, this species is classified with the other wigeons in the dabbling duck genus Mareca. It is the New World counterpart of the Eurasian wigeon.
The three dowitchers are medium-sized long-billed wading birds in the genus Limnodromus. The English name "dowitcher" is from Iroquois, recorded in English by the 1830s.
The dunlin 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.
The grey plover or black-bellied plover is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding.
The willet is a large shorebird in the family Scolopacidae. It is a relatively large and robust sandpiper and is the largest of the species called "shanks" in the genus Tringa. Its closest relative is the lesser yellowlegs, a much smaller bird with a very different appearance apart from the fine, clear, and dense pattern of the neck, which both species show in breeding plumage. It breeds in North America and the West Indies and winters in southern North America, Central America, the West Indies and South America.
The greater yellowlegs is a large shorebird in the family Scolopacidae. It breeds in central Canada and southern Alaska and winters in southern North America, Central America, the West Indies and South America.
The lesser yellowlegs is a medium-sized shorebird. It breeds in the boreal forest region of North America.
The long-billed dowitcher is a medium-sized shorebird with a relatively long bill belonging to the sandpiper family, Scolopacidae. In breeding plumage, adults are characterized by a beautiful rufous head and underparts with a darker mottled back and a large white upper rump only seen in flight. They feed in various freshwater habitats with their bill underwater in a "sewing machine" motion and are known to have an exciting mating display where males chase females in flight. The genus, Limnodromus is Ancient Greek from limne, "marsh" and dromos, "racer". The specific scolopaceus is Neo-Latin for "snipe-like", from Latin scolopax, scolopacis, a snipe or woodcock. The English name is from Iroquois and was first recorded in 1841.
The Asian dowitcher is a rare medium-large wader.
The marbled godwit is a large migratory shorebird in the family Scolopacidae. On average, it is the largest of the four species of godwit.
The bar-tailed godwit is a large and strongly migratory wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of Australia and New Zealand. The migration of the subspecies Limosa lapponica baueri across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over 29,000 km (18,020 mi).
The Sardinian warbler is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.
The gull-billed tern, formerly Sterna nilotica, is a tern in the family Laridae. It is widely distributed and breeds in scattered localities in Europe, Asia, northwest Africa, and the Americas. The Australian gull-billed tern was previously considered a subspecies.
The two-barred crossbill or white-winged crossbill is a small passerine bird in the finch family Fringillidae. It breeds in the coniferous forests of North America and the Palearctic.
The Savannah sparrow is a small New World sparrow that is the only member of the genus Passerculus. It is a widespread and abundant species that occupies open grassland habitats in North America.
The bristle-thighed curlew is a medium-sized shorebird that breeds in Alaska and winters on tropical Pacific islands.
The wandering tattler, is a medium-sized wading bird. It is similar in appearance to the closely related gray-tailed tattler, T. brevipes. The tattlers are unique among the species of Tringa for having unpatterned, greyish wings and backs, and a scaly breast pattern extending more or less onto the belly in breeding plumage, in which both also have a rather prominent supercilium.
The southern boubou is a bushshrike. Though these passerine birds and their relations were once included with true shrikes in the Laniidae, they are not closely related to that family.
The green-barred woodpecker or green-barred flicker is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in Argentina, Bolivia, Brazil, Paraguay and Uruguay.
The yellow-crowned bishop is a species of passerine bird in the family Ploceidae native to Africa south of the Sahara. It is highly sexually dimorphic in its breeding season, during which the male adopts a distinctive yellow and black plumage, contrasting with the female's predominantly brown coloration. Four subspecies are recognised.
