The Swiss naturalist Conrad Gessner gave the northern gannet the name Anser bassanus or scoticus in the 16th century, and noted that the Scots called it a solendguse. [4] The former name was also used by the English naturalist Francis Willughby in the 17th century; the species was known to him from a colony in the Firth of Forth and from a stray bird that was found near Coleshill, Warwickshire.
The Australasian gannet (Morus serrator), also known as the Australian gannet or tākapu, is a large seabird of the booby and gannet family, Sulidae. Adults are mostly white, with black flight feathers at the wingtips and lining the trailing edge of the wing. The central tail feathers are also black.
Young gannets were historically used as a food source, a tradition still practised in Ness, Scotland, where they are called "guga". Like examples of continued traditional whale harvesting , the modern-day hunting of gannet chicks results in great controversies as to whether it should continue to be given "exemption from the ordinary protection ...
For the most part, an interim taxonomy of 21 species is accepted by ITIS and many other researchers, though by no means all—in 2004 Penhallurick and Wink called for the number of species to be reduced to 13 (including the lumping of the Amsterdam albatross with the wandering albatross), [13] although this paper was itself controversial.

They normally nest in large and dense colonies on flat islands or on flat ledges of the steeply sloping Mercury Island off Namibia. The world population was estimated in 1996 to number about 340,000 birds, with 12% in Namibia and 88% in South Africa. The largest colony of this bird, with over 140,000 birds, is found on Malgas Island, South Africa.
The grey-headed albatross (Thalassarche chrysostoma) also known as the gray-headed mollymawk, is a large seabird from the albatross family. It has a circumpolar distribution, nesting on isolated islands in the Southern Ocean and feeding at high latitudes, further south than any of the other mollymawks. Its name derives from its ashy-gray head ...
The Tristan albatross is practically indistinguishable from the snowy albatross at sea but is smaller and has a slightly darker back. It is 110 cm (43 in) from beak to tail [9] and has a wingspan of up to 3.05 m (10.0 ft). [10]
