The masked booby (Sula dactylatra), also called the masked gannet or the blue-faced booby, is a large seabird of the booby and gannet family, Sulidae. First described by the French naturalist René-Primevère Lesson in 1831, the masked booby is one of six species of booby in the genus Sula. It has a typical sulid body shape, with a long pointed ...
Gannets can achieve speeds of 100 km/h (62.13 mph) as they strike the water, enabling them to catch fish at a much greater depth than most airborne birds. [ 5 ] The gannet's supposed capacity for eating large quantities of fish has led to "gannet" becoming a description of somebody with a voracious appetite.
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 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 name is derived from súla, the Old Norse and Icelandic word for the other member of the family Sulidae, the gannet. [ 5 ] The English name booby was possibly based on the Spanish slang term bobo , meaning "stupid", [ 6 ] as these tame birds had a habit of landing on board sailing ships, where they were easily captured and eaten.
There exists no single definition of which groups, families and species are seabirds, and most definitions are in some way arbitrary. Elizabeth Shreiber and Joanna Burger, two seabird scientists, said, "The one common characteristic that all seabirds share is that they feed in saltwater; but, as seems to be true with any statement in biology, some do not."
The magnificent frigatebird (Fregata magnificens), frigate petrel [2] or man o' war [3] is a seabird of the frigatebird family Fregatidae.With a length of 89–114 centimetres (2 ft 11 in – 3 ft 9 in) and wingspan of 2.17–2.44 m (7 ft 1 in – 8 ft 0 in) it is the largest species of frigatebird.
The southern giant petrel (Macronectes giganteus), also known as the Antarctic giant petrel, giant fulmar, stinker, and stinkpot, is a large seabird of the southern oceans. Its distribution overlaps broadly with the similar northern giant petrel, though it overall is centered slightly further south.
