Metaves
Metaves ("other birds") is a controversial group proposed by Fain & Houde (2004) and later rescued on the studies of Ericson ''et al.'' (2006)Ericson, P.G.P. ''et al.'' (2006Diversification of Neoaves: integration of molecular sequence data and fossils. Biology Letters, 2(4):543–547 and Hackett ''et al.'' (2008).Hackett, S.J. ''et al.'' (2008A Phylogenomic Study of Birds Reveals Their Evolutionary History ''Science'', 320(5884):1763–1768. This group consists of several lineages that diversified early in Neornithes evolution. These lineages include Strisores (hummingbirds, swifts, nightjars and allies), pigeons, sandgrouses, mesites, Eurypygae ( sunbittern and kagu), tropicbirds and Mirandornithes (flamingos and grebe Grebes () are aquatic diving birds in the order (biology), order Podicipediformes ().

Strisores
Strisores ( ), sometimes called nightbirds, is a clade of birds that includes the living family (biology), families and order (biology), orders Caprimulgidae (nightjars, nighthawks and allies), Nyctibiidae (potoos), Steatornithidae (oilbirds), Podargidae (frogmouths), Apodiformes (swifts and hummingbirds), as well as the Aegotheliformes (owlet-nightjars) whose distinctness was only recently realized. The Apodiformes (which include the "Trochiliformes" of the Sibley-Ahlquist taxonomy) and the Aegotheliformes form the Apodimorphae, Daedalornithes. Description The material evidence for this group is very equivocal; the most ancient Strisores are quite nondescript tree-dwellers but already tend towards peculiarly apomorphic feet, and no Cretaceous fossils are known. Torpor and other metabolic peculiarities are frequently found in this group, perhaps more often than in any other bird lineage. The synapomorphies that define this clade are the ''ossa maxillaria'' separated by a large c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurypyga Helias
The sunbittern (''Eurypyga helias'') is a bittern-like bird of tropical regions of the Americas, and the Monotypic taxon, sole member of the family (biology), family Eurypygidae (sometimes spelled Eurypigidae) and genus ''Eurypyga''. It is found in Central and South America, and has three subspecies. The sunbittern shows both morphological and molecular similarities with the kagu (''Rhynochetos jubatus'') of New Caledonia, indicating a Gondwanan origin, both species being placed in the clade Eurypygiformes.del Hoyo, J. Elliott, A. & Sargatal, J. (editors). (1996) ''Handbook of the Birds of the World. Volume 3: Hoatzin to Auks''. Lynx Edicions. Taxonomy The sunbittern was traditionally placed in the Gruiformes, but this was always considered preliminary. Altogether, the bird is most similar to another bird that was provisionally placed in the Gruiformes, the kagu (''Rhynochetos jubatus'').

Eurypygae
Eurypygiformes is an order formed by the kagus, comprising two species in the family Rhynochetidae endemic to New Caledonia, and the sunbittern (''Eurypyga helias'') from the tropical regions of the Americas. Its closest relatives appear to be the tropicbirds of the tropical Atlantic, Indian, and Pacific oceans. Classification The affinities of Eurypygiformes are not very well resolved. The group consists of two families from a Gondwanan lineage of birds. Based on some morphological characteristics, they were initially classed as members of the family Ardeidae, and later the Gruiformes. According to Jarvis, et al.'s 2014 "Whole-genome analyses resolve early branches in the tree of life of modern birds", the group is distantly related to the Phaethontiformes. The oldest known fossil eurypygiform is an indeterminate fossil eurypygid from the Early Eocene-aged Green River Formation of the United States. When seen as a gruiform, the kagu is generally considered related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neognathae
Neognathae (; ) is an infraclass of birds, called neognaths, within the class Aves of the clade Archosauria. Neognathae includes the majority of living birds; the exceptions being the tinamous and the flightless ratites, which belong instead to the sister taxon Palaeognathae. There are nearly 10,000 living species of neognaths. The earliest fossils are known from the very end of the Cretaceous with the oldest known members being ''Teviornis'' and ''Vegavis'', but molecular clocks suggest that neognaths originated sometime in the first half of the Late Cretaceous, about 90 million years ago. Since then, they have undergone adaptive radiation, producing the diversity of form, function, and behavior that exists today. Neognathae includes the order (biology), order Passeriformes (perching birds), one of the largest orders of land vertebrates, containing some 60% of living birds. Passeriformes is twice as species-rich as Rodentia and about five times as species-rich as bat, Chiroptera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurypygimorphae
Eurypygimorphae or Phaethontimorphae is a clade of birds that contains the orders Phaethontiformes (tropicbirds) and Eurypygiformes (kagu and sunbittern) recovered by genome analysis. The relationship was first identified in 2013 based on their nuclear genes. This group was defined in the ''PhyloCode'' by George Sangster and colleagues in 2022 as "the least inclusive crown clade containing '' Phaethon aethereus'', ''Eurypyga helias The sunbittern (''Eurypyga helias'') is a bittern-like bird of tropical regions of the Americas, and the Monotypic taxon, sole member of the family (biology), family Eurypygidae (sometimes spelled Eurypigidae) and genus ''Eurypyga''. It is found ...'', and '' Rhynochetos jubatus''". Historically these birds were placed at different parts of the tree, with tropicbirds in Pelecaniformes and the kagu and sunbittern in Gruiformes. Some genetic analyses have placed the eurypygimorph taxa in the controversial and obsolete clade Metaves, with uncertai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kagu
The kagu or cagou (''Rhynochetos jubatus'') is a crested, long-legged, and bluish-grey bird endemism, endemic to the dense mountain forests of New Caledonia. It is the only surviving member of the genus ''Rhynochetos'' and the family Rhynochetidae, although a second species has been described from the fossil record. Measuring in length, it has pale grey plumage and bright red legs. Its 'nasal corns' are a unique feature not shared with any other bird. Almost flightless, it spends its time on or near the ground, where it hunts its invertebrate prey and builds a nest of sticks on the forest floor. Both parents share incubation of a single egg (biology), egg, as well as rearing the chick. It has proven vulnerable to introduced predators and is threatened with extinction. Etymology The name kagu is derived from the Melanesian languages, Melanesian names for the species. The species is variously known as the ''kavu'' or ''kagou'' in the New Caledonian languages, Kanak language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropicbirds
Tropicbirds are a family, Phaethontidae, of tropical pelagic seabirds. They are the sole living representatives of the order Phaethontiformes. For many years they were considered part of the Pelecaniformes, but genetics indicates they are most closely related to the Eurypygiformes. There are three species in one genus, ''Phaethon''. The scientific names are derived from Ancient Greek ''phaethon'', "sun". They have predominantly white plumage with elongated tail feathers and small feeble legs and feet. Taxonomy, systematics and evolution The genus ''Phaethon'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The name is from Ancient Greek ''phaethōn'' meaning "sun". The type species was designated as the red-billed tropicbird (''Phaethon aethereus'') by George Robert Gray in 1840. Tropicbirds were traditionally grouped in the order Pelecaniformes, which contained the pelicans, cormorants and shags, darters, g ...

Sandgrouse
Sandgrouse is the common name for Pteroclidae (), a family (biology), family of sixteen species of bird, members of the order Pterocliformes (). They are traditionally placed in two Genus, genera. The two central Asian species are classified as ''Syrrhaptes'' and the other fourteen species, from Africa and Asia, are placed in the genus ''Pterocles''. They are ground-dwelling birds restricted to treeless, open country, such as plains, savannahs, and semi-deserts. They are distributed across northern, southern, and eastern Africa, Madagascar, the Middle East, and India through central Asia. The ranges of the black-bellied sandgrouse and the pin-tailed sandgrouse even extend into the Iberian Peninsula and France, and Pallas's sandgrouse occasionally Irruptive growth, breaks out in large numbers from its normal range in Asia. Description Sandgrouse have small, pigeon-like heads and necks and sturdy compact bodies. They range in size from in length and from in weight. Their feathers ...

Hummingbird
Hummingbirds are birds native to the Americas and comprise the Family (biology), biological family Trochilidae. With approximately 366 species and 113 genus, genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central America, Central and South America. As of 2024, 21 hummingbird species are listed as Endangered species, endangered or critically endangered, with numerous species declining in population. Hummingbirds have varied specialized characteristics to enable rapid, maneuverable flight: exceptional metabolism, metabolic capacity, adaptations to high altitude, sensitive visual and communication abilities, and long-distance migration in some species. Among all birds, male hummingbirds have the widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring in length. The smallest is the bee hummingbird, which weighs less than , and the largest is the giant hummingbird, weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swift (bird)
The Apodidae, or swifts, form a family of highly aerial birds. They are superficially similar to swallows, but are not closely related to any passerine species. Swifts are placed in the order Apodiformes along with hummingbirds. The treeswifts are closely related to the true swifts, but form a separate family, the Hemiprocnidae. Resemblances between swifts and swallows are due to convergent evolution, reflecting similar life styles based on catching insects in flight. The family name, Apodidae, is derived from the Greek ἄπους (''ápous''), meaning "footless", a reference to the small, weak legs of these most aerial of birds.Jobling (2010) pp. 50–51.Kaufman (2001) p. 329. The tradition of depicting swifts without feet continued into the Middle Ages, as seen in the heraldic martlet. Taxonomy Taxonomists have long classified swifts and treeswifts as relatives of the hummingbirds, a judgment corroborated by the discovery of the Jungornithidae (apparently swift-like hum ...

Nightjar
Nightjars are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae and order Caprimulgiformes, characterised by long wings, short legs, and very short bills. They are sometimes called bugeaters, their primary source of food being insects. Some New World species are called nighthawks. The English word ''nightjar'' originally referred to the European nightjar. Nightjars are found all around the world, with the exception of Antarctica, and certain island groups such as the Seychelles. They can be found in a variety of habitats, most commonly the open country with some vegetation. They usually nest on the ground, with a habit of resting and roosting on roads. The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. Typical nightjars have rictal bristles, longer bills, and softer plumage. The colour of their plumage and their unusual perching habits help conceal them during the day. Sy ...
