Charadriiform
Charadriiformes (, from ''Charadrius'', the type genus of family Charadriidae) is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds. Taxonomy, systematics and evolution The order was formerly divided into three suborders: * The waders (or "Charadrii"): typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments. * The gulls and their allies (or "Lari"): these are generally larger species which take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environments. * The auks (or "Alcae") ...

Wader
245px, A flock of Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the smaller species found ...

Pluvianellidae
The Magellanic plover (''Pluvianellus socialis'') is a rare wader found only in southernmost South America. Taxonomy It was long placed in with the other plovers in the family Charadriidae; however, behavioural evidence suggested they were distinct, and molecular studies confirmed this, suggesting that they are actually more closely related to the sheathbills, a uniquely Antarctic family. As such it is now placed in its own family, Pluvianellidae. Description This species is in its structure and habits much like a turnstone, but it cannot be confused with any other wader species. Its upperparts and breast are pale grey, and the rest of the underparts are white. It has short red legs, a black bill and red eyes. In young birds, the eyes and legs are yellowish in colour, and the plumage is grey overall with scaling. The call is a dovelike ''coo''. Distribution and habitat This species is not a long-distance migrant, although some birds move further north in southern Argentina in ...

Pedionomidae
The plains-wanderer (''Pedionomus torquatus'') is a bird, the only representative of family Pedionomidae and genus ''Pedionomus''. It is endemic to Australia. The majority of the remaining population is found in the Riverina region of New South Wales. Description The plains-wanderer is a quail-like ground bird, measuring 15–19 cm. It is such an atypical bird that it is placed in an entire family of its own, Pedionomidae. The adult male is light brown above, with fawn-white underparts with black crescents. The adult female is substantially larger than the male, and has a distinctive white-spotted black collar. They have excellent camouflage, and will first hide at any disturbance. If approached too closely, they will run rather than fly, at which they are very poor. Females lay four eggs, which the male then incubates. Taxonomy It was formerly believed to be related to the buttonquails and thus placed in the gamebird order Galliformes or with the cranes and rails ...

Lari (bird)
The suborder Lari is the part of the order Charadriiformes Charadriiformes (, from '' Charadrius'', the type genus of family Charadriidae) is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water ... that includes the gulls, terns, skuas and Skimmer (bird), skimmers; the rest of the order is made up of the waders and snipes. The auks are now placed into the Lari too, following recent research. Sometimes, the buttonquails are also placed here, but the molecular data and fossil record rather suggests they are a quite Basal (phylogenetics), basal offshoot along with the snipe-like and aberrant waders.Paton ''et al.'', 2003; Thomas ''et al.'', 2004; Paton & Baker, 2006 The larids are generally larger species that take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environme ...

Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ciconiiformes
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family called Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 19 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacanidae
The jacanas (sometimes referred to as Jesus birds or lily trotters) are a group of tropical waders in the family Jacanidae. They are found in the tropical regions around the world. They are noted for their elongated toes and toenails that allow them to spread out their weight while foraging on floating or semi-emergent aquatic vegetation. They are also among the rare groups of birds in which females are larger, and several species maintain harems of males in the breeding season with males solely responsible for incubating eggs and taking care of the chicks. Etymology and pronunciation The pronunciation of the word jacana is debated. ''Jacana'' is Linnæus' scientific Latin spelling of the Portuguese ''jaçanã'' which in turn is derived from a Tupi name of the bird, ''ñaha'nã''. The Portuguese word is pronounced approximately . As in façade, Provençal, and araçari, the Ç is meant to be pronounced as an S. US dictionaries give various pronunciations: , , as well as th ...

Rostratulidae
The Rostratulidae, commonly known as the painted-snipes, are a family of wading birds that consists of two genera: ''Rostratula'' and '' Nycticryphes''. Description The painted-snipes are short-legged, long-billed birds similar in shape to the true snipes, but their plumage is much more striking. There is sexual dimorphism in both size and plumage, with the males being duller overall and smaller. All three species have large forward pointing eyes. Phylogenetics The family Rostratulidae encompasses two genera and four species, one of which is extinct. Painted-snipes superficially resemble true snipes, but the two taxa are not closely related. Instead the similarity can be attributed to convergent evolution where both groups have been subjected to similar selective pressures, thus promoting the evolution of analogous features such as a long slender bill and legs, mottled cryptic plumage and characteristic body proportions. While less similar in general morphology, the species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibidorhynchidae
The ibisbill (''Ibidorhyncha struthersii'') is a bird related to the waders, but sufficiently distinctive to merit its own family Ibidorhynchidae. It is grey with a white belly, red legs and long down-curved bill, and a black face and black breast band. It occurs on the shingle riverbanks of the high plateau of central Asia and the Himalayas. Taxonomy The ibisbill belongs to the order Charadriiformes which also includes the sandpipers, plovers, terns, auks, gulls, skuas and others. Although its evolutionary relationships are not fully understood, the ibisbill appears to be most closely related to a group including the oystercatchers, avocets, stilts and ''Pluvialis'' plovers, but sufficiently distinctive to merit its own family, Ibidorhynchidae. There are no subspecies. The species was described in 1831 by Vigors based on painting by John Gould although Brian Hodgson had sent a manuscript to the Asiatic Society of Bengal two years earlier describing it as the "Red-billed Er ...

Recurvirostridae
The Recurvirostridae are a family of birds in the wader suborder Charadrii. It contains two distinct groups of birds, the avocets (one genus) and the stilts (two genera). Description Avocets and stilts range in length from and in weight from ; males are usually slightly bigger than females. All possess long, thin legs, necks, and bills. The bills of avocets are curved upwards, and are swept from side to side when the bird is feeding in the brackish or saline wetlands they prefer. The bills of stilts, in contrast, are straight. The front toes are webbed, partially in most stilts, and fully in avocets and the banded stilt, which swim more. The majority of species' plumage has contrasting areas of black and white, with some species having patches of buff or brown on the head or chest. The sexes are similar. Their vocalizations are usually yelps of one or two syllables. Distribution and habitat Avocets and stilts are a cosmopolitan family, being distributed on all the world's c ...
