Dowitcher
The three dowitchers are medium-sized long-billed wading birds in the genus ''Limnodromus''. The English name "dowitchers" is from Iroquois, recorded in English by the 1830s. The OED's earliest example is from 1841, but full-text searching gives results that suggest it was already in common use by the mid-1830s. They resemble godwits in body and bill shape, and the reddish underparts in summer, but are much shorter legged, more like snipe to which they are also somewhat more closely related. All three are strongly migratory. The two North American species are difficult to separate in most plumages, and were considered a single species for many years. The Asian bird is rare and not well known. Taxonomy The genus ''Limnodromus'' was introduced in 1833 by the German naturalist Prince Maximilian of Wied-Neuwied to accommodate a single species, the short-billed dowitcher. The name combines the Ancient Greek ''limnē'' meaning "marsh" with ''-dromos'' meaning "-racer" or "-runner" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-billed Dowitcher
The long-billed dowitcher (''Limnodromus scolopaceus'') 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 New 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 Long-billed dowitcher is nearly identical in appearance to the Short-billed dowitcher and was only recognized as a separate species in 1950 by Pitelka. Between the two, the best distinguishing field mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-billed Dowitcher
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. It is strongly migratory; it completely vacates in breeding areas during the snow-bound months. 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. It and the very similar long-billed dowitcher were considered one species until 1950. 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 substan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asian Dowitcher
The Asian dowitcher (''Limnodromus semipalmatus'') is a rare medium-large wader. Description Adults have dark legs and a long straight dark bill, somewhat shorter than that of the long-billed dowitcher. The body is brown on top and reddish underneath in breeding plumage. The tail has a black and white barred pattern. The winter plumage is largely grey. Their breeding habitat is grassy wetlands in inland Siberia and Manchuria. They migrate to southeast Asia as far south as northern Australia, although both the breeding and wintering areas are poorly known. This bird is always found on coasts during migration and wintering. 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. Closer species The confusion species for this bird is not, as might be expected, one of the American dowitchers, which in any case do not overlap in range, because the Asian bird is much larger.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Iroquois
The Iroquois ( or ), officially the Haudenosaunee ( meaning "people of the longhouse"), are an Iroquoian-speaking confederacy of First Nations peoples in northeast North America/ Turtle Island. They were known during the colonial years to the French as the Iroquois League, and later as the Iroquois Confederacy. The English called them the Five Nations, comprising the Mohawk, Oneida, Onondaga, Cayuga, and Seneca (listed geographically from east to west). After 1722, the Iroquoian-speaking Tuscarora people from the southeast were accepted into the confederacy, which became known as the Six Nations. The Confederacy came about as a result of the Great Law of Peace, said to have been composed by Deganawidah the Great Peacemaker, Hiawatha, and Jigonsaseh the Mother of Nations. For nearly 200 years, the Six Nations/Haudenosaunee Confederacy were a powerful factor in North American colonial policy, with some scholars arguing for the concept of the Middle Ground, in that Europe ...

Godwit
The godwits are a group of large, long-billed, long-legged and strongly migratory waders of the bird genus ''Limosa''. Their long bills allow them to probe deeply in the sand for aquatic worms and molluscs. In their winter range, they flock together where food is plentiful. They frequent tidal shorelines, breeding in northern climates in summer and migrating south in winter. A female bar-tailed godwit made a flight of 29,000 km (18,000 mi), flying of it without stopping. In 2020 a male bar-tailed godwit flew about non-stop in its migration from Alaska to New Zealand, previously a record for avian non-stop flight. In October 2022, a 5 month old, male bar-tailed godwit was tracked from Alaska to Tasmania, a trip that took 11 days, and recorded a non-stop flight of . The godwits can be distinguished from the curlews by their straight or slightly upturned bills, and from the dowitchers by their longer legs. The winter plumages are fairly drab, but three species have r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
