Ardeae
Phaethoquornithes is a clade of birds that contains Eurypygimorphae and Aequornithes, found in 2014 by genome analysis. Members of Eurypygimorphae were originally classified in the obsolete group Metaves, and Aequornithes were classified as the sister taxon to Musophagiformes or Gruiformes. Ardeae has also been used in older classifications as a suborder of Ciconiiformes containing herons and related species. Cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms.

Kagu
The kagu or cagou (''Rhynochetos jubatus'') is a crested, long-legged, and bluish-grey bird 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, as well as rearing the chick. It has proven vulnerable to introduced predators and is threatened with extinction. Taxonomy and systematics The kagu's affinities are not well resolved. It was long one of the most enigmatic birds and in more recent times is usually affiliated with the Gruiformes. It was initially classed as a member of the clade A ... [...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. 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 Metaves ("other birds") is a controversial group proposed by Fain & Houde (2004) and later rescued on the studies of Ericson ''et al.''

Aequornithes
Aequornithes (, from Latin ''aequor'', expanse of water + Greek ''ornithes'', birds), or core water birds are defined as "the least inclusive clade containing Gaviidae and Phalacrocoracidae". 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 and auks (Charadriiformes), or the Anseriformes. 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 sister group of the Aequornithes in the clade Ardeae.

Gaviiformes
Gaviiformes is an order of aquatic birds containing the loons or divers and their closest extinct relatives. Modern gaviiformes are found in many parts of North America and northern Eurasia (Europe, Asia and debatably Africa), though prehistoric species were more widespread. Classification and evolution There are five living species, and all are placed in the genus '' Gavia''. The loons were formerly often considered to be the most ancient of the northern hemisphere bird families; this idea grew basically out of the perceived similarity of shape and (probably) habits between loons and the entirely unrelated extinct Cretaceous order Hesperornithiformes. In particular ''Enaliornis'', which was apparently an ancestral and plesiomorphic member of that order, was sometimes used to support claims of Albian (Early Cretaceous) Gaviiformes. More recently, it has become clear that the Anseriformes (waterfowl) and the Galliformes are the most ancient groups of modern birds, and these bei ...

Pelecaniformes
The Pelecaniformes are an order of medium-sized and large waterbirds found worldwide. As traditionally—but erroneously—defined, they encompass all birds that have feet with all four toes webbed. Hence, they were formerly also known by such names as totipalmates or steganopodes. Most have a bare throat patch (gular patch), and the nostrils have evolved into dysfunctional slits, forcing them to breathe through their mouths. They also have a pectinate nail on their longest toe. This is shaped like a comb and is used to brush out and separate their feathers. They feed on fish, squid, or similar marine life. Nesting is colonial, but individual birds are monogamous. The young are altricial, hatching from the egg helpless and naked in most. They lack a brood patch. The pelicans, shoebill and hamerkop form a clade within the order, with their next closest relatives being a clade containing the herons, ibises and spoonbills.

Cormorant
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOC adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wings; some cormorant species have been ...

Booby
A booby is a seabird in the genus ''Sula'', part of the family Sulidae. Boobies are closely related to the gannets (''Morus''), which were formerly included in ''Sula''. Systematics and evolution The genus ''Sula'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The type species is the brown booby. The name is derived from ''súla'', the Old Norse and Icelandic word for the other member of the family Sulidae, the gannet. The English name "booby" was possibly based on the Spanish slang term ''bobo'', meaning "stupid", as these tame birds had a habit of landing on board sailing ships, where they were easily captured and eaten. Owing to this, boobies are often mentioned as having been caught and eaten by shipwrecked sailors, notably William Bligh of the ''Bounty'' and his adherents during their famous voyage after being set adrift by Fletcher Christian and his followers. Six of the ten extant Sulidae species called ''boobies'' are in the genus ''Sul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suliformes
The order Suliformes (, dubbed "Phalacrocoraciformes" by ''Christidis & Boles 2008'') is an order recognised by the International Ornithological Congress, International Ornithologist's Union. In regard to the recent evidence that the traditional Pelecaniformes is polyphyletic, it has been suggested that the group be divided to reflect the true evolutionary relationships, a 2017 study indicated that they are most closely related to Otidiformes (bustards) and Ciconiiformes (storks). Systematics and evolution Of the families in Pelecaniformes, only Pelecanidae, Balaenicipitidae, and Scopidae remain. The tropicbird family Phaethontidae has since been moved to their own order Phaethontiformes. Genetic analysis seems to show that the Pelecaniformes is actually closely related to the Ardeidae and Threskiornithidae. As for the Suliformes, they are distantly related to the current Pelecaniformes. According to Hackett ''et al''. (2008), Gaviformes, loons, Sphenisciformes, penguins, Ciconiif ...

Sphenisciformes
Penguins ( order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy penguin, which stands around tall and weighs . Today, larger penguins generally inhabit colder regions, and smaller penguins in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalassarche Chlororhynchos 1838
The mollymawks are a group of medium-sized albatrosses that form the genus ''Thalassarche''. The name has sometimes been used for the genus ''Phoebetria'' as well, but these are usually called sooty albatrosses. They are restricted to the Southern Hemisphere, where they are the most common of the albatrosses. They were long considered to be in the same genus as the great albatrosses, ''Diomedea'', but a study of their mitochondrial DNA showed that they are a monophyletic taxon related to the sooty albatrosses, and they were placed in their own genus. Taxonomy The genus ''Thalassarche'' was introduced in 1853 by the German naturalist Ludwig Reichenbach with the black-browed albatross as the type species. The genus name combines the Ancient Greek ''thalassa'' meaning "sea" and ''arkhē'' meaning "power" or "command" (from ''arkhō'', to govern). The word ''mollymawk'', which dates to the late 17th century, comes from the Dutch ''mallemok'', which means ''mal'' – foolish and ''m ...
