Pelecanimorphae
Pelecanimorphae is a clade of aequornithean birds that comprises the orders Ciconiiformes, Suliformes and 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 n .... In the past the name has been used as a homonym for Pelecaniformes. References Neognathae {{bird-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
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 ...

Pelecanidae
The Pelecanidae is a family of pelecaniform birds within the Pelecani that contains two genera: the extinct ''Eopelecanus'' and the extant '' Pelecanus''. The family was monotypic until the description of ''Eopelecanus'' in 2021. Pelecanids have existed since the late Eocene (Priabonian The Priabonian is, in the ICS's geologic timescale, the latest age or the upper stage of the Eocene Epoch or Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of t ...) and they still exist today.

Shoebill
The shoebill (''Balaeniceps rex'') also known as the whalebill, whale-headed stork or shoe-billed stork, is a very large long-legged wading bird. It derives its name from its enormous shoe-shaped bill. It has a somewhat stork-like overall form and has previously been classified with the storks in the order Ciconiiformes based on this morphology. However, genetic evidence places it with pelicans and herons in the Pelecaniformes. The adult is mainly grey while the juveniles are more brown. It lives in tropical East Africa in large swamps from South Sudan to Zambia. Taxonomy The shoebill may have been known to Ancient Egyptians but was not classified until the 19th century, after skins and eventually live specimens were brought to Europe. John Gould very briefly described it in 1850 from the skin of a specimen collected on the upper White Nile by the English traveller Mansfield Parkyns. Gould provided a more detailed description in the following year. He placed the species in it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balaenicipitidae
Balaenicipitidae is a family of birds in the order Pelecaniformes, although it was traditionally placed in Ciconiiformes. The shoebill is the sole extant species and its closest relative is the hamerkop (''Scopus umbretta''), which belongs to another family. It has the following genera: *'' Balaeniceps'' *†''Goliathia ''Goliathia'' is an extinct genus of bird.

Hamerkop
The hamerkop (''Scopus umbretta'') is a medium-sized wading bird. It is the only living species in the genus ''Scopus'' and the family Scopidae. The species and family was long thought to sit with the Ciconiiformes but is now placed with the Pelecaniformes, and its closest relatives are thought to be the pelicans and the shoebill. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name after the Afrikaans word for hammerhead. It is a medium-sized waterbird with brown plumage. It is found in Africa, Madagascar and Arabia, living in a wide variety of wetlands, including estuaries, lakesides, fish ponds, riverbanks, and rocky coasts. The hamerkop is a sedentary bird that often shows local movements. The hamerkop takes a wide range of prey, mostly fish and amphibians, but shrimps, insects and rodents are taken too. Prey is usually hunted in shallow water, either by sight or touch, but the species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scopus (bird)
''Scopus'' is a genus of wading birds containing the hamerkop ''(Scopus umbretta)'' and its extinct Pliocene relative, ''Scopus xenopus''. This genus is the sole representative of the family Scopidae. Taxonomy Hamerkops were traditionally included in the Ciconiiformes, but are now thought to be closer to the Pelecaniformes. Recent studies have found that its closest relatives are the pelicans and shoebill The shoebill (''Balaeniceps rex'') also known as the whalebill, whale-headed stork or shoe-billed stork, is a very large long-legged wading bird.

Heron
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' 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 considere ...

Threskiornithidae
The family Threskiornithidae includes 36 species of large wading birds. The family has been traditionally classified into two subfamilies, the ibises and the spoonbills; however recent genetic studies have cast doubt on this arrangement, and have found the spoonbills to be nested within the Old World ibises, and the New World ibises as an early offshoot. Taxonomy The family Threskiornithidae was formerly known as Plataleidae. The spoonbills and ibises were once thought to be related to other groups of long-legged wading birds in the order Ciconiiformes. A recent study found that they are members of the order Pelecaniformes. In response to these findings, the International Ornithological Congress (IOC) recently reclassified Threskiornithidae and their sister taxa Ardeidae under the order Pelecaniformes instead of the previous order of Ciconiiformes. Whether the two subfamilies are reciprocally monophyletic is an open question. The South American Checklist Committee's entry for th ...

Ardei
Ardei is a suborder of order Pelecaniformes that include the families Ardeidae (herons, egrets, and bitterns) and Threskiornithidae (ibises and spoonbills). Traditionally the ardeids and threskiornithids were classified in the order Ciconiiformes along with Ciconiidae (storks), Phoenicopteridae (flamingos), Scopidae (hamerkop), Balaenicipitidae (shoebill), and even Cathartidae (New World vultures and condors). However, there were some osteological studies that have questioned the monophyly of Ciconiiformes, suggesting that the ardeids and threskiornithids originated from early gruiforms, with the latter being a transitionary taxon to order Charadriiformes. The polyphyly nature of Ciconiiformes is supported by recent genomic studies that have found support threskiornithids, ardeids, scopids and balaenicipitids being closely related to Pelecanidae (pelicans). The exact relationship between ardeids, threskiornithids and suborder Pelcani is still being investigated with two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
