Terns
Terns are seabirds in the family (biology), family Laridae, subfamily Sterninae, that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated in eleven genus, genera in a subgroup of the family Laridae, which also includes several genera of gulls and the Skimmer (bird), skimmers (''Rynchops''). They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below with a contrasting black cap to the head, but the marsh terns, the black-bellied tern, the Inca tern, and some Noddy (tern), noddies have dark body plumage for at least part of the year. The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. Terns are long-lived birds and are relatively free from natural predators and parasites; mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Tern
The common tern (''Sterna hirundo'') is a seabird in the family Laridae. This bird has a circumpolar distribution, its four subspecies breeding in Temperateness, temperate and subarctic regions of Europe, Asia and North America. It is strongly bird migration, migratory, wintering in coastal Tropics, tropical and Subtropics, subtropical regions. Breeding adults have light grey upperparts, white to very light grey underparts, a black cap, orange-red legs, and a narrow pointed bill. Depending on the subspecies, the bill may be mostly red with a black tip or all black. There are several similar species, including the partly Sympatry, sympatric Arctic tern, which can be separated on plumage details, leg and bill colour, or Bird vocalization, vocalisations. Breeding in a wider range of habitats than any of its relatives, the common tern nests on any flat, poorly vegetated surface close to water, including beaches and islands, and it readily adapts to artificial substrates such as ...

Caspian Tern
The Caspian tern (''Hydroprogne caspia'') is a species of tern, with a subcosmopolitan but scattered distribution. Despite its extensive range, it is monotypic of its genus, and has no accepted subspecies. The genus name is from Ancient Greek ''hudro-'', "water-", and Latin ''progne'', "swallow". The specific ''caspia'' is from Latin and, like the English name, refers to the Caspian Sea. Description It is the world's largest tern with a length of , a wingspan of and a weight of . Adult birds have black legs, and a long thick red-orange bill with a small black tip. They have a white head with a black cap and white neck, belly, and tail. The upper wings and back are pale grey; the underwings are pale with dark primary feathers. In-flight, the tail is less forked than other terns, and wingtips are black on the underside. In winter, the black cap is still present (unlike many other terns), but with some white streaking on the forehead. The call is a loud heron-like croak. Distribu ...

Sandwich Tern
The Sandwich tern (''Thalasseus sandvicensis'') is a tern in the family Laridae. It is very closely related to the lesser crested tern (''T. bengalensis''), Chinese crested tern (''T. bernsteini''), Cabot's tern (''T. acuflavidus''), and elegant tern (''T. elegans'') and has been known to interbreed with both elegant and lesser crested. It breeds in the Palearctic from Europe to the Caspian Sea and winters in South Africa, India, and Sri Lanka. The Sandwich tern is a medium-large tern with grey upperparts, white underparts, a yellow-tipped black bill, and a shaggy black crest which becomes less extensive in winter with a white crown. Young birds bear grey and brown scalloped plumage on their backs and wings. It is a vocal bird. It nests in a ground scrape and lays one to three eggs. Like all ''Thalasseus'' terns, the Sandwich tern feeds by plunge diving for fish, usually in marine environments, and the offering of fish by the male to the female is part of the courtship disp ...

Laridae
Laridae is a family of seabirds in the order Charadriiformes that includes the gulls, terns (including white terns), noddies, and skimmers. It includes around 100 species arranged into 22 genera. They are an adaptable group of mostly aerial birds found worldwide. Taxonomy The family Laridae was introduced (as Laridia) by the French polymath Constantine Samuel Rafinesque in 1815. Historically, Laridae were restricted to the gulls, while the terns were placed in a separate family, Sternidae, and the skimmers in a third family, Rynchopidae. The noddies were traditionally included in Sternidae. In 1990 Charles Sibley and Jon Ahlquist included auks and skuas in a broader family Laridae. A molecular phylogenetic study by Baker and colleagues published in 2007 found that the noddies in the genus '' Anous'' formed a sister group to a clade containing the gulls, skimmers, and the other terns. To create a monophyletic family group, Laridae was expanded to include the genera that had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychoprion
''Onychoprion'' is a genus of four species of terns in the family Laridae. The genus name is from Ancient Greek , "claw" or "nail", and , "saw". As a group, they have been variously called "brown-winged terns" or "brown-backed terns", though only one species is actually brown; the other three are dark grey or black. Species Although the genus ''Onychoprion'' was first described in 1832 by Johann Georg Wagler, the species in the genus were generally retained within the larger genus '' Sterna'', the genus that holds most terns, until a study in 2005 showed that this treatment was paraphyletic, with these four species less closely related to typical ''Sterna'' terns, than several other terns long treated in other genera like '' Chlidonias'' and '' Larosterna''.Bridge, E.

Thalasseus
''Thalasseus'', the crested terns, is a genus of eight species of medium-large to large terns in the family Laridae. The species have a worldwide distribution in temperate and tropical seas, mostly between about 43° N and S latitude, but to 60° N in the warm waters of the North Atlantic Current in the eastern North Atlantic Ocean; they do not occur in colder arctic or antarctic waters. Several of the species are abundant and well-known birds in their ranges; one is however extremely rare and critically endangered. This genus had originally been distinguished by Friedrich Boie in 1822, but had been little used (with one exception in 1978) until a 2005 study confirmed the need for a separate genus for the crested terns. ''Thalasseus'' terns are large for terns, from 35–53 cm long, with lesser crested tern marginally the smallest, and greater crested tern marginally the largest. The underside plumage is white in all species, while the wings and back vary from pale silvery gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roseate Tern
The roseate tern (''Sterna dougallii'') is a species of tern in the family Laridae. The genus name ''Sterna'' is derived from Old English "stearn", "tern", and the specific ''dougallii'' refers to Scottish physician and collector Dr Peter McDougall (1777–1814). "Roseate" refers to the bird's pink breast in breeding plumage. Taxonomy English naturalist George Montagu described the roseate tern in 1813. Genetically, it is most closely related to the white-fronted tern (''S. striata''), with their common ancestor a sister lineage to the black-naped tern (''S. sumatrana''). This species has a number of geographical subspecies, differing mainly in bill colour and minor plumage details. ''S. d. dougallii '' breeds on the Atlantic coasts of Europe and North America, and winters south to the Caribbean and west Africa. Both the European and North American populations have been in long-term decline, though active conservation measures have reversed the decline in the last few yea ...

Anous
The noddies, forming the genus ''Anous'', is a genus of seabirds in family Laridae which also contains the gulls, terns and skimmers. The genus contains five species. The noddies inhabit tropical oceans and have a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. They nest in colonies on cliffs or in short trees or shrubs, seldom on the ground. The female lays one egg in each breeding season.''Anous'' TOLWEB These birds feed on small fish which they catch by dipping their bills beneath the surface while flying; they do not |
Large-billed Tern
The large-billed tern (''Phaetusa simplex'') is a species of tern in the family Laridae. It is placed the monotypic genus ''Phaetusa''. It is found in most of South America (east of the Andes and north of the Pampas). It has occurred as a vagrant in Aruba, Bermuda, Cuba, Panama and the United States. Its natural habitats are rivers and freshwater lakes. Taxonomy The large-billed tern was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other terns in the genus '' Sterna'' and coined the binomial name ''Sterna simplex''. Gmelin based his description on the "simple tern" that had been described in 1785 by the English ornithologist John Latham in his book ''A General Synopsis of Birds'' from a specimen that had been collected in Cayenne, French Guiana. The large-billed tern is now the only species placed in the genus ''Phaetusa'' that was introduced for the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
