Leucophaeus
''Leucophaeus'' is a small genus of medium-sized New World gulls, most of which are dark in plumage, usually with white crescents above and below the eyes. They were placed in the genus ''Larus'' until recently. The genus name ''Leucophaeus'' is from 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 ... ''leukos'', "white", and ''phaios'', "dusky".

Laughing Gull
The laughing gull (''Leucophaeus atricilla'') is a medium-sized gull of North and South America. Named for its laugh-like call, it is an opportunistic omnivore and scavenger. It breeds in large colonies mostly along the Atlantic coast of North America, the Caribbean, and northern South America. The two subspecies are: ''L. a. megalopterus'' – which can be seen from southeast Canada down to Central America, and ''L. a. atricilla'' which appears from the West Indies to the Venezuelan islands. The laughing gull was long placed in the genus ''Larus'' until its present placement in ''Leucophaeus'', which follows the American Ornithologists' Union. Name The genus name ''Leucophaeus'' is from Ancient Greek λευκός : ''leukós'', "white", and φαιός : ''phaios'', "dusky". The specific ''atricilla'' is from Latin ''atra'', "black", " unlucky" or "malevolent" and ''cilla'', "tail". According to the ''Helm Dictionary of Scientific Bird Names'', Linnaeus may have intended to wri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franklin's Gull
Franklin's gull (''Leucophaeus pipixcan'') is a small (length 12.6–14.2 in, 32–36 cm) gull. The genus name ''Leucophaeus'' is from Ancient Greek ''leukos'', "white", and ''phaios'', "dusky". The specific ''pipixcan'' is a Nahuatl name for a type of gull. Description It breeds in central provinces of Canada and adjacent states of the northern United States. It is a migratory bird, wintering in Argentina, the Caribbean, Chile, and Peru. The summer adult's body is white and its back and wings are much darker grey than all other gulls of similar size except the larger laughing gull. The wings have black tips with an adjacent white band. The bill and legs are red. The black hood of the breeding adult is mostly lost in winter. Young birds are similar to the adult but have less developed hoods and lack the white wing band. They take three years to reach maturity. Measurements: * Length: 12.6-14.2 in (32-36 cm) * Weight: 8.1-10.6 oz (230-300 g) * Wingspan: 33.5-37.4 in (85-9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grey Gull
The grey gull, also known as garuma gull (''Leucophaeus modestus'') is a medium-sized gull native to South America. Unusual among gulls, it breeds inland in the extremely dry Atacama Desert in northern Chile, although it is present as a non-breeding bird along much of the Pacific coast of South America. Description The sexes are similar in grey gulls. Adults grow to a length of about and weigh some . The head is white in summer but brownish-grey in winter. The body and wings are grey with the dorsal surface rather darker than the ventral region. The flight feathers are black and the inner primaries and the secondaries have white tips, visible in flight. The tail has a band of black with a white trailing edge. The legs and beak are black and the iris is brown.Josep del Hoyo, Andrew Elliott, Jordi Sargatal (Eds.): ''Handbook of the Birds of the World''. Volume 3: Hoatzin to Auks. Lynx Edicions 1996, , p. 602 The call is similar to that of the laughing gull (''Leucophaeus atricilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolphin Gull
The dolphin gull (''Leucophaeus scoresbii''), sometimes erroneously called the red-billed gull (a somewhat similar but unrelated species from New Zealand), is a gull native to southern Chile and Argentina, and the Falkland Islands. It is a coastal bird inhabiting rocky, muddy and sandy shores and is often found around seabird colonies. They have greyish feathers, and the feathers on their wings are a darker shade. Dolphin gulls have a varied diet, eating many things ranging from mussels to carrion. The modern scientific name ''Leucophaeus scoresbii'', together with the obsolete common name Scoresby's gull, commemorates the English explorer William Scoresby (1789–1857). Distribution The dolphin gull is found round the coasts of Chile, Argentina and the Falkland Islands. It is a vagrant to South Georgia and the South Sandwich Islands. It is found on rocky coasts and in the vicinity of other colonies of seabirds, slaughterhouses, sewage outflows and farmyards. Behaviour The dolph ...

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 ...

Lava Gull
The lava gull (''Leucophaeus fuliginosus''), also known as the dusky gull, is a medium-sized gull and a member of the "hooded gull" group. It is most closely related to the Laughing gull and Franklin's gull and is the rarest gull in the world. It is endemic to the Galapagos Islands. Taxonomy and systematics First described by John Gould in 1841 from a specimen collected on Santiago Island in the Galápagos. The species is sometimes placed in the genus ''Larus''. It is possibly closely related to the laughing gull. Description The lava gull is a distinctive gull, and weighs . The adult plumage consists of a sooty brown to black head, which unlike other dark hooded gulls doesn't vary by season. The wings are dark gray with a contrasting white line on the leading edge, thought to play a function in displays and camouflage. Its dark gray body contrasts with a paler gray belly. The uppertail is white and grey lower down. The bill and legs are black, and the inside of the mouth is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bi ...
