Ichthyaetus
''Ichthyaetus'' is a genus of gulls. The genus name is from Ancient Greek ''ikhthus'', "fish", and ''aetos'', "eagle". They were previously included in the genus ''Larus ''Larus'' is a large genus of gulls with worldwide distribution (by far the greatest species diversity is in the Northern Hemisphere).

Audouin's Gull
Audouin's gull (''Ichthyaetus audouinii'') is a large gull restricted to the Mediterranean and the western coast of Saharan Africa and the Iberian Peninsula. The genus name is from Ancient Greek ''ikhthus'', "fish", and ''aetos'', "eagle", and the specific ''audouinii'' and the English name are after the French naturalist Jean Victoire Audouin. It breeds on small islands colonially or alone, laying 2–3 eggs on a ground nest. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. In the late 1960s, this was one of the world's rarest gulls, with a population of only 1,000 pairs. It has established new colonies, but remains rare with a population of about 10,000 pairs. This species, unlike many large gulls, rarely scavenges, but is a specialist fish eater, and is therefore strictly coastal and pelagic. This bird will feed at night, often well out to sea, but also slowly patrols close into beaches, occasionally dangling its legs to increase drag. ...

Mediterranean Gull
The Mediterranean gull (''Ichthyaetus melanocephalus'') is a small gull. The scientific name is from Ancient Greek. The genus ''Ichthyaetus'' is from ''ikhthus'', "fish", and ''aetos'', "eagle", and the specific ''melanocephalus'' is from ''melas'', "black", and ''-kephalos'' "-headed". This gull breeds almost entirely in the Western Palearctic, mainly in the south east, especially around the Black Sea, and in central Turkey. There are colonies elsewhere in southern Europe, and this species has undergone a dramatic range expansion in recent decades. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. Description The Mediterranean gull is slightly larger and bulkier than the black-headed gull with a heavier bill and longer, darker legs. The breeding plumage adult is a distinctive white gull, with a very pale grey mantle and wings with white primary feathers without black tips. The black hood extends down the nape and shows distinct white eye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pallas' Gull
Pallas's gull (''Ichthyaetus ichthyaetus''), also known as the great black-headed gull, is a large bird species. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. The scientific name is from Ancient Greek. ''Ichthyaetus'' is from ''ikhthus'', "fish", and ''aetos'', "eagle". Distribution This species breeds in colonies in marshes and islands from southern Russia to Mongolia. It is migratory, wintering in the eastern Mediterranean, Arabia and India. This gull nests on the ground, laying between two and four eggs. It occurs in western Europe only as a rare vagrant. In Great Britain a recent review left a single occurrence in 1859 as the only acceptable record of this bird. The species also occurs as a vagrant in differing parts of the Indian Ocean, south of its normal range, and along the northern and eastern coasts of Africa, where it visits annually on an irregular basis.

Sooty Gull
The sooty gull (''Ichthyaetus hemprichii'') is a species of gull in the family Laridae, also known as the Aden gull or Hemprich's gull. It is found in Bahrain, Djibouti, Egypt, Eritrea, India, Iran, Israel, Jordan, Kenya, Lebanon, Maldives, Mozambique, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sri Lanka, Sudan, Tanzania, United Arab Emirates, and Yemen. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. The sooty gull is named in honour of the German naturalist Wilhelm Hemprich who died in 1825 while on a scientific expedition to Egypt and the Middle East with his friend Christian Gottfried Ehrenberg.Bauer, A. M. (2000) 'The Symbolae Physicae and the herpetology of Hemprich and Ehrenberg’s expedition to Egypt and the Middle East" '' International Society for the History and Bibliography of Herpetology Newsletter and Bulletin'' 2(1): pp. 8–16 Distribution and habitat The sooty gull is native to the Red Sea, the Gulf of A ...

White-eyed Gull
The white-eyed gull (''Ichthyaetus leucophthalmus'') is a small gull that is endemic to the Red Sea. Its closest relative is the sooty gull. It is one of the world's rarest gulls, with a population of 4,000 – 6,500 pairs. The species is classed as Near Threatened by the IUCN; human pressure and oil pollution are deemed the major threats. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''.Pons J.M., Hassanin, A., and Crochet P.A.(2005). ''Phylogenetic relationships within the Laridae (Charadriiformes: Aves) inferred from mitochondrial markers.'' Molecular Phylogenetics and Evolution 37(3):686–699 Morphology Adult white-eyed gulls have a black hood in breeding plumage, which extends down onto the upper throat, and on the neck-sides is bordered below by a narrow white bar. The upperparts and inner upperwings are medium-dark grey; the breast is mid-grey but the rest of the underparts are white. The secondaries are black with a white trail ...

Relict Gull
The relict gull or Central Asian gull (''Ichthyaetus relictus'') is a medium-sized gull. It was believed to be an eastern race of the Mediterranean gull until 1971 and was traditionally placed in the genus ''Larus''. Description The gull is 44 to 45 cm long with a stocky, thick body. Non-breeding adults feature uniformly dark-smudged ear-coverts and hind crown, white-tipped wings, prominent, isolated black subterminal markings on outer primaries, and no white leading edge to outer wing. Breeding birds have black hoods (including napes) with grey-brown foreheads, and broad, white, half-moon colouring behind, below, and above their eyes. Their legs are orange and their bills scarlet. The name comes from its status as a relict species.Ming Ma, Ying Chen, Kedeerhan Bayahen, Baowen Hu, Fei Li, Jiaqing Wu, Xiang Gao, Yu Mei"Seasonal changes in the number of Relict Gull (''Larus relictus'') at Ebinur Lake, Western China" ''Journal of Arid Land'', 2010, volume 2, number 2, pp 15 ...

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.
