The great skua (Stercorarius skua), sometimes known by the name bonxie in Britain, is a large seabird in the skua family Stercorariidae. It is roughly the size of a herring gull . It mainly eats fish caught at the sea surface or taken from other birds.
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 ...
The great frigatebird (Fregata minor) is a large seabird in the frigatebird family.There are major nesting populations in the tropical Pacific Ocean, such as Hawaii and the Galápagos Islands; in the Indian Ocean, colonies can be found in the Seychelles (on Aldabra and Aride Islands) and Mauritius, and there is a tiny population in the South Atlantic, mostly on and around St. Helena and ...
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 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 southern royal albatross has a length of 112 to 123 cm (44–48 in) [13] and a mean weight of 8.5 kg (19 lb). At Campbell Island , 11 males were found to have a mean mass of 10.3 kg (23 lb) and 7 females were found to have a mean mass of 7.7 kg (17 lb), thus may be heavier on average than most colonies of wandering albatross.

Larger species, such as the great skua, regularly kill and eat adult seabirds, such as puffins and gulls and have been observed killing birds as large as a grey heron. [5] On the breeding grounds, the three, more slender northern breeding species commonly eat lemmings. Those species that breed in the southern oceans largely feed on fish that ...
