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 International Ornithologists' Union (IOU) 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 the names "cormorant" and "shag" 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 wing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Cormorant
The great cormorant (''Phalacrocorax carbo''), also known as just cormorant in Britain, as black shag or kawau in New Zealand, formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. It breeds in much of the Old World, Australasia, and the Atlantic coast of North America. Taxonomy The great cormorant was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Pelecanus carbo''. Linnaeus specified the type location as "Europe", but this was restricted to the "rock-nesting form of the north Atlantic Ocean" by the German ornithologist Ernst Hartert in 1920. The great cormorant is now one of 12 species placed in the genus '' Phalacrocorax'' that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. The genus name is Latinised Anc ...

Phalacrocorax
''Phalacrocorax'' is a genus of fish-eating birds in the cormorant family Phalacrocoracidae. Members of this genus are also known as the Old World cormorants. Taxonomy The genus ''Phalacrocorax'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the great cormorant (''Phalacrocorax carbo'') as the type species. ''Phalacrocorax'' is the Latin word for a cormorant. Formerly, many other species of cormorant were classified in ''Phalacrocorax'', but most of these have been split out into different genera. A 2014 study found ''Phalacrocrax'' to be the sister genus to '' Urile'', which are thought to have split from each other between 8.9–10.3 million years ago. Current taxonomy A molecular phylogenetic study published in 2014 found that the genus ''Phalacrocorax'' contains 12 species. This taxonomy was adopted by the IUCN Red List and BirdLife International, and later by the IOC. Alternative taxonomies Formerly, the gen ...

Little Pied Cormorant
The little pied cormorant, little shag or kawaupaka (''Microcarbo melanoleucos'') is a common species of Australasian waterbird, found around the coasts, islands, Estuary, estuaries, and inland waters of Australia, New Guinea, New Zealand, Timor-Leste and Indonesia, and around the islands of the south-western Pacific and the subantarctic. It is a small short-billed cormorant usually black above and white below with a yellow bill and small crest, although a mostly black white-throated form predominates in New Zealand. Three subspecies are recognised. Until recently most authorities referred to this species as ''Phalacrocorax melanoleucos''. Taxonomy The species is known as the little pied cormorant in Australia, and as the little shag or by the Māori language, Māori name of kawaupaka in New Zealand. The term white-throated shag is also reserved for the melanistic form there. The little pied cormorant was originally described by French naturalist Louis Pierre Vieillot in 1817. I ...

Nannopterum
''Nannopterum'' is a genus of cormorant comprising three species. They are found throughout the Americas, hence the common name American cormorants. These species were formerly classified in the genus ''Phalacrocorax''. A molecular phylogenetic study of the cormorants published in 2014 found that these three species formed a clade that was sister to the genus '' Leucocarbo''. To create monophyletic genera, the three species were moved the resurrected genus ''Nannopterum'' that had been introduced in 1899 by English ornithologist Richard Bowdler Sharpe to accommodate the flightless cormorant. The genus ''Nannopterum'' is thought to have split from ''Leucocarbo'' between 6.7 - 8.0 million years ago. The genus name ''Nannopterum'' combines the Ancient Greek ''nannos'' meaning "dwarf" with ''pteron'' meaning "wing". This name was coined for the flightless cormorant, which does indeed have small wings. Genetic studies have found that the neotropic The Neotropical realm is one o ...

Microcarbo
''Microcarbo'' is a genus of fish-eating birds, known as cormorants, of the family Phalacrocoracidae. The genus was formerly subsumed within '' Phalacrocorax''. ''Microcarbo'' has been recognized as a valid genus by the IOC's World Bird List on the basis of work by Siegel-Causey (1988), Kennedy et al. (2000), and Christidis and Boles (2008). As suggested by the name, this genus contains the smallest of the world's cormorants. It is also the most basal, having diverged from the rest of the family between 12.8 and 15.4 million years ago. Taxonomy The genus ''Microcarbo'' was introduced in 1856 by the French naturalist Charles Lucien Bonaparte with the pygmy cormorant as the type species. The name combines the Ancient Greek ''mikros'' meaning "small" with the genus name ''Carbo'' that was introduced by Bernard Germain de Lacépède Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French natural hi ...

European Shag
The European shag or common shag (''Gulosus aristotelis'') is a species of cormorant. It is the only member of the monotypic genus ''Gulosus''. It breeds around the rocky coasts of western and southern Europe, southwest Asia and north Africa, mainly wintering in its breeding range except for the northernmost birds. In Britain this seabird is usually referred to as simply the shag. The scientific genus name derives from the Latin for glutton. The species name ''aristotelis'' commemorates the Greek philosopher Aristotle. Taxonomy The European shag was formerly classified within the genus '' Phalacrocorax'', but a 2014 study found it to be significantly more diverged than the clade containing ''Phalacrocorax'' and '' Urile'', but basal to the clade containing '' Nannopterum'' and '' Leucocarbo'', and thus classified it in its own genus, ''Gulosus''. The IOC followed this classification in 2021. ''Gulosus'' is thought to have split from the ''Nannopterum''-''Leucocarbo'' clade ...

Urile
''Urile'' is a genus of birds in the family Cormorant, Phalacrocoracidae, commonly known as North Pacific cormorants. It contains 3 extant and 1 recently extinct species, all of which are or were found in the Pacific Ocean, North Pacific Ocean. Members of this genus were formerly classified within the genus ''Phalacrocorax''. Based on the results of a molecular phylogenetic study published in 2014, the genus ''Phalacrocorax'' was split and these species were moved to the resurrected genus ''Urile'' that had been introduced in 1856 by the French naturalist Charles Lucien Bonaparte with the red-faced cormorant as the type species. ''Urile'' is thought to have split from ''Phalacrocorax'' 8.9 - 10.3 million years ago. The genus contains four species, of which one is now extinct.

Leucocarbo
''Leucocarbo'' is a genus of birds in the family Phalacrocoracidae. Several species within the genus are collectively known as blue-eyed shags. This is a group of closely related cormorant taxa. Many have a blue, purple or red ring around the eye (not a blue iris); other shared features are white underparts (at least in some individuals) and pink feet. They are found around the colder parts of the Southern Hemisphere, especially near southern South America, Antarctica, and New Zealand. Many are endemic to remote islands. Determining which types are species and which are subspecies of what larger species is problematic; various recent authorities have recognized from 8 to 14 species and have placed them in a variety of genera. The common names are even more confusing, "like myriad footprints criss-crossing in the snow and about as easy to disentangle." Only one common name is given for most species here. Taxonomy The genus ''Leucocarbo'' was introduced in 1856 by the French ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Bird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys, sea eagles, fish eagles, fish owls, and fishing owls, hunt aquatic prey but do not stay in water for long and live predominantly over dry land, and are not considered water birds. The term waterb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSPB
The Royal Society for the Protection of Birds (RSPB) is a Charitable_organization#United_Kingdom, charitable organisation registered in Charity Commission for England and Wales, England and Wales and in Office of the Scottish Charity Regulator, Scotland. It was founded in 1889. It works to promote bird conservation, conservation and protection of birds and the wider Natural environment, environment through public awareness campaigns, petitions and through the operation of Nature Reserve, nature reserves throughout the United Kingdom. In 2021/22 the RSPB had revenue of £157 million, 2,200 employees, 10,500 volunteers and 1.1 million members (including 195,000 youth members), making it one of the world's largest wildlife conservation organisations. The RSPB has many local groups and maintains 222 nature reserves. History The origins of the RSPB lie with two groups of women, both formed in 1889: * The Plumage League was founded by Emily Williamson at her house in Didsbury, Ma ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
