Laridae
Laridae is a family of seabirds in the order Charadriiformes that includes the gulls, terns, skimmers and kittiwakes. 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 previously been in Stern ...

Gull
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German ''Möwe'', Danish ''måge'', Swedish ''mås'', Dutch ''meeuw'', Norwegian ''måke''/''måse'' and French ''mouette'', and can still be found in certain regional dialects. Gulls are typically medium to large in size, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustac ...

Tern
Terns are seabirds in the family Laridae that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated as a subgroup of the family Laridae which includes gulls and skimmers and consists of eleven genera. 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 Inca tern, and some noddies have dark 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; most species are declining in numbers due directly or indirectly to human activities, including habitat loss, pollution, disturbance, an ...

Skimmer (bird)
The skimmers, forming the genus ''Rynchops'', are tern-like birds in the family Laridae. The genus comprises three species found in South Asia, Africa, and the Americas. They were formerly known as the scissorbills. The three species are the only birds with distinctive uneven bills, where the lower mandible is longer than the upper. This remarkable adaptation allows them to fish in a unique way, flying low and fast over streams. Their lower mandible skims or slices over the water's surface, ready to snap shut any small fish unable to dart clear. The skimmers are sometimes included within the gull family Laridae but separated in other treatments which consider them as a sister group of the terns. The black skimmer has an additional adaptation and is the only species of bird known to have slit-shaped pupils. Their bills fall within their field of binocular vision, which enables them to carefully position their bill and capture prey. They are agile in flight and gather in large flock ...

Charadriiformes
Charadriiformes (, from ''Charadrius'', the type genus of family Charadriidae) is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds. Taxonomy, systematics and evolution The order was formerly divided into three suborders: * The waders (or "Charadrii"): typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments. * The gulls and their allies (or " Lari"): these are generally larger species which take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environments. * The auks (or "Alcae" ...

Kittiwake
The kittiwakes (genus ''Rissa'') are two closely related seabird species in the gull family Laridae, the black-legged kittiwake (''Rissa tridactyla'') and the red-legged kittiwake (''Rissa brevirostris''). The epithets "black-legged" and "red-legged" are used to distinguish the two species in North America, but in Europe, where ''Rissa brevirostris'' is not found, the black-legged kittiwake is often known simply as kittiwake, or more colloquially in some areas as tickleass or tickleace. The name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. The genus name ''Rissa'' is from the Icelandic name ''Rita'' for the black-legged kittiwake. Description The two species are indeed physically very similar. They have a white head and body, grey back, grey wings tipped solid black and a bright yellow bill. Black-legged kittiwake adults are somewhat larger (roughly in length with a wingspan of ) than red-legged kittiwakes ( in length with a wingspan around ). Other diff ...

Gelochelidon
''Gelochelidon'' is a genus of terns. It was considered a monotypic genus until the Australian tern was split from the gull-billed tern. Taxonomy The genus ''Gelochelidon'' was introduced in 1830 by the German zoologist Alfred Brehm. The type species is the gull-billed tern. The name combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic peri ... ''gelaō'' meaning "to laugh" with ''khelidōn'' meaning "swallow".

Thalasseus
''Thalasseus'', the crested terns, is a genus of eight species of terns in the family Laridae. It has a worldwide distribution, and many of its species are abundant and well-known birds in their ranges. This genus had originally been created by Friedrich Boie in 1822, but had been abandoned until a 2005 study confirmed the need for a separate genus for the crested terns. These large terns breed in very dense colonies on coasts and islands, and exceptionally inland on suitable large freshwater lakes close to the coast. They nest in a ground scrape. ''Thalasseus'' terns feed by plunge-diving for fish, almost invariably from the sea. They usually dive directly, and not from the "stepped-hover" favoured by, for example, the Arctic tern. The offering of fish by the male to the female is part of the courtship display. These species have long thin sharp bills, usually a shade of yellow or orange except in the Sandwich tern and Cabot's tern where the bills are black with yellow ti ...

Larus
''Larus'' is a large genus of gulls with worldwide distribution (by far the greatest species diversity is in the Northern Hemisphere). Many of its species are abundant and well-known birds in their ranges. Until about 2005–2007, most gulls were placed in this genus, but this arrangement is now known to be polyphyletic, leading to the resurrection of the genera ''Ichthyaetus'', ''Chroicocephalus'', ''Leucophaeus'', and '' Hydrocoloeus'' (this last had been recognized more often than the other genera) for several species traditionally included in ''Larus''. They are in general medium to large birds, typically grey or white, often with black markings on their heads or wings. They have stout, longish bills and webbed feet. The taxonomy of the large gulls in the herring and lesser black-backed complex is very complicated, with different authorities recognising between two and eight species. Taxonomy The genus ''Larus'' was introduced in 1758 by the Swedish naturalist Carl Linn ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Onychoprion
''Onychoprion'', the "brown-backed terns", is a genus of seabirds in the family Laridae. The genus name is from Ancient Greek , "claw" or "nail", and , "saw". Species Although the genus was first described in 1832 by Johann Georg Wagler the four species in the genus were until 2005 retained in the larger genus ''Sterna'', the genus that holds most terns.Bridge, E. S.; Jones, A. W. & Baker, A. J. (2005)A phylogenetic framework for the terns (Sternini) inferred from mtDNA sequences: implications for taxonomy and plumage evolution. ''Molecular Phylogenetics and Evolution'' 35: 459–469. Three of the four species are tropical, and one has a sub-polar breeding range. The sooty tern has a pan-tropical distribution; the bridled tern also breeds across the Tropical Atlantic and Indian Ocean but in the central Pacific it is replaced by the spectacled tern. The Aleutian tern breeds around Alaska and Siberia but winters in the tropics around South East Asia. ''Manutara'' is the Rapa Nui ...

Sterna
''Sterna'' is a genus of terns in the bird family Laridae. The genus used to encompass most "white" terns indiscriminately, but mtDNA sequence comparisons have recently determined that this arrangement is paraphyletic. It is now restricted to the typical medium-sized white terns occurring near-globally in coastal regions.Bridge, E. S.; Jones, A. W. & Baker, A. J. (2005)A phylogenetic framework for the terns (Sternini) inferred from mtDNA sequences: implications for taxonomy and plumage evolution. ''Molecular Phylogenetics and Evolution'' 35: 459–469. Taxonomy The genus ''Sterna'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The type species is the common tern (''Sterna hirundo''). ''Sterna'' is derived from Old English "stearn" which appears in the poem '' The Seafarer''; a similar word was used to refer to terns by the Frisians. Species The genus contains 13 species.
