Phaethoquornithes
Phaethoquornithes is a clade of birds that contains Eurypygimorphae and Aequornithes, which was first recovered by genome analysis in 2014. Members of Eurypygimorphae were originally classified in the obsolete group Metaves, and Aequornithes were classified as the sister taxon to Musophagiformes or Gruiformes. This group has also been informally called Ardeae. Older classifications have used Ardeae in a different sense, as a suborder of Ciconiiformes containing herons and related species. George Sangster and colleagues in 2022 named and defined this clade in the ''PhyloCode'' as the least inclusive crown clade containing '' Phaethon aethereus'' and '' Pelecanus onocrotalus'', but not '' Apus apus'', '' Charadrius hiaticula'', '' Musophaga violacea'', or ''Passer domesticus''.

Aequornithes
Aequornithes (, from Latin ''aequor'', expanse of water + Greek ''ornithes'', birds), or core water birds, are defined in the ''PhyloCode'' as "the least inclusive crown clade containing '' Pelecanus onocrotalus'' and '' Gavia immer''", that is, the last common ancestor of the great white pelican and the common loon, as well as its descendants, extinct and extant. The monophyly of the group is currently supported by several molecular phylogenetic studies. Aequornithes includes the clades Gaviiformes, Sphenisciformes, Procellariiformes, Ciconiiformes, Suliformes and Pelecaniformes. It does not include several unrelated groups of aquatic birds such as flamingos and grebes ( Mirandornithes), shorebirds, gulls, and auks (Charadriiformes), or the Anseriformes (waterfowl). Based on a whole-genome analysis of the bird orders, the kagu and sunbittern ( Eurypygiformes) and the three species of tropicbirds ( Phaethontiformes) together styled as the Eurypygimorphae are the closest s ...

Paleocene
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Herons
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 75 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genus '' Botaurus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and '' Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered to constitute a sepa ...

Passer Domesticus
The house sparrow (''Passer domesticus'') is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus ''Passer'', the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musophaga Violacea
The violet turaco, also known as the violaceous plantain eater (''Tauraco violaceus''), is a large turaco, a group of African otidimorphae. Characteristics These are unmistakable birds, but shy and often inconspicuous in the treetops. They are approximately long, including a long tail and a bill. They boast a winglength of and weigh approximately . The plumage is glossy violet, except for the yellow forehead, chestnut crown and white ear coverts; the bill is thick and red. In flight, the violet turaco's crimson primary flight feathers contrast with the violet plumage. The red colour in the wings is typical of turacos. Habitat It is resident of West Africa, and has an extremely large range from Senegal through to Nigeria, with isolated populations in Chad and the Central African Republic. It occurs in tropical savannas, wetlands, woodlands and forests. Diet Diet consists of fruit, and they are quite partial to figs, but they will also eat leaves, buds, flowers, insects, snail ...

Charadrius Hiaticula
The common ringed plover or ringed plover (''Charadrius hiaticula'') is a species of bird in the family Charadriidae. It breeds across much of northern Eurasia, as well as Greenland. Taxonomy The common ringed plover was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the current binomial name ''Charadrius hiaticula''. Linnaeus specified the type locality as "Europa & America" but this is now restricted to Sweden. The specific epithet ''hiaticula'' is late Medieval Latin for a plover. Three subspecies are recognised: * ''C. h. psammodromus'' Salomonsen, 1930 – Arctic of North Atlantic: Ellesmere Island and Baffin Island (northeast Canada, sporadic); Greenland, Iceland, Faroe Islands and Svalbard (north of Norway) * ''C. h. hiaticula'' Linnaeus, 1758 – temperate east North Atlantic region: British Isles and northwest France to south Scandinavia and Baltic States * ''C. h. tundrae'' ( Lowe, 1915) ...

Apus Apus
The common swift (''Apus apus'') is a medium-sized bird, superficially similar to the barn swallow or house martin but somewhat larger, though not stemming from those passerine species, being in the order Apodiformes. The resemblances between the groups are due to convergent evolution, reflecting similar contextual development. The swifts' nearest relatives are the New World hummingbirds and the Southeast Asian treeswifts. Its scientific name ''Apus'' is Latin for a swift, thought by the ancients to be a type of swallow with no feet (from Ancient Greek α, ''a'', "without", and πούς, ''pous'', "foot"). Swifts have very short legs which they use primarily for clinging to vertical surfaces (hence the German name ''Mauersegler'', literally meaning "wall-glider"). They never settle voluntarily on the ground where they would be vulnerable to accidents and predation, and non-breeding individuals may spend up to ten months in continuous flight. Taxonomy The common swift was one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelecanus Onocrotalus
The great white pelican (''Pelecanus onocrotalus'') also known as the eastern white pelican, rosy pelican or simply white pelican is a bird in the pelican family. It breeds from southeastern Europe through Asia and Africa, in swamps and shallow lakes. The great white pelican has been rated as a species of least concern on the IUCN Red List of Endangered Species (IUCN). It is listed under Appendix I of the Convention on the Conservation of Migratory Species of Wild Animals, Annexure I under the EU Birds Directive on the Conservation of Wild Birds, and Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats. It is also listed within 108 Special Protection Areas in the European Union. It occurs within 43 Important Bird Areas (IBAs) in its European range. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) is applied. Taxonomy The great w ...

Phaethon Aethereus
The red-billed tropicbird (''Phaethon aethereus'') is a tropicbird, one of three closely related species of seabird of tropical oceans. Superficially resembling a tern in appearance, it has mostly white plumage with some black markings on the wings and back, a black mask and, as its common name suggests, a red bill. Most adults have that are about two times their body length, with those in males being generally longer than those in females. The red-billed tropicbird itself has three subspecies recognized, including the nominate. The subspecies ''mesonauta'' is distinguished from the nominate by the rosy tinge of its fresh plumage, and the subspecies ''indicus'' can be differentiated by its smaller size, more restricted mask, and more orange bill. This species ranges across the tropical Atlantic, eastern Pacific, and Indian Oceans. The nominate is found in the southern Atlantic Ocean, the subspecies ''indicus'' in the waters off of the Middle East and in the Indian Ocean, and the ...

PhyloCode
The ''International Code of Phylogenetic Nomenclature'', known as the ''PhyloCode'' for short, is a formal set of rules governing phylogenetic nomenclature. Its current version is specifically designed to regulate the naming of clades, leaving the governance of species names up to the rank-based nomenclature codes ('' ICN'', '' ICNCP'', '' ICNP'', '' ICZN'', '' ICVCN''). The ''PhyloCode'' is associated with the International Society for Phylogenetic Nomenclature (ISPN). The companion volume, ''Phylonyms'', establishes 300 taxon names under ''PhyloCode'', serving as examples for those unfamiliar with the code. RegNum is an associated online database for registered clade names. The ''PhyloCode'' regulates phylogenetic nomenclature by providing rules for deciding which associations of names and definitions are considered established, which of those will be considered homonyms or synonyms, and which one of a set of synonyms or homonyms will be considered accepted (generally the one ...

Gruiformes
The Gruiformes ( ) are an order containing a considerable number of living and extinct bird families, with a widespread geographical diversity. Gruiform means "crane-like". Traditionally, a number of wading and terrestrial bird families that did not seem to belong to any other order were classified together as Gruiformes. These include 15 species of large cranes, about 145 species of smaller crakes and rails, as well as a variety of families comprising one to three species, such as the Heliornithidae, the limpkin, or the Psophiidae. Other birds have been placed in this order more out of necessity to place them ''somewhere''; this has caused the expanded Gruiformes to lack distinctive apomorphies. Recent studies indicate that these "odd Gruiformes" are if at all only loosely related to the cranes, rails, and relatives ("core Gruiformes"). Systematics There are only two suprafamilial clades (natural groups) among the birds traditionally classified as Gruiformes. Rails ( Ra ...

Ciconiiformes
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family 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 20 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 Ansch ...
