Giant petrels form a genus, Macronectes, from the family Procellariidae, which consists of two living and one extinct species. They are the largest birds in this family. Both extant species in the genus are native to the Southern Hemisphere. Giant petrels are extremely aggressive predators and scavengers, inspiring another common name, the ...
The southern giant petrel measures 86 to 99 cm (34–39 in) with a wingspan of 185 to 205 cm (6 ft 1 in – 6 ft 9 in). Both this and the northern giant petrel vary considerably in size, with southern colonies averaging larger than northern colonies, in line with Bergmann's rule. Due to the large amount of size variability, it is difficult to ...
Order: Procellariiformes Family: Procellariidae. The procellariids are the main group of medium-sized "true petrels", characterized by united nostrils with medium nasal septum, and a long outer functional primary flight feather. Southern giant petrel, Macronectes giganteus LC; Northern giant petrel, Macronectes halli LC
The fulmarine petrels include the largest procellariids, the giant petrels, as well as the two fulmar species, the snow petrel, the Antarctic petrel, and the Cape petrel. The fulmarine petrels are a diverse group with differing habits and appearances, but are linked morphologically by their skull features, particularly the long prominent nasal ...
Family Hydrobatidae (northern storm petrels) are similar to the austral storm petrels but have longer more pointed wings and most species have forked tails. [21] Family Procellariidae (shearwaters, fulmarine petrels, gadfly petrels, and prions) are a varied group of small or medium-sized seabirds, the largest being the giant petrels. They are ...
Petrels encompass three of the four extant families within the Procellariiformes order, namely Procellariidae (fulmarine petrels, gadfly petrels, diving petrels, prions, and shearwaters), Hydrobatidae (northern storm petrels), and Oceanitidae (austral storm petrels). The remaining family in Procellariiformes is the albatross family, Diomedeidae.
Macronectes tinae is an extinct species of giant petrel from the Pliocene of New Zealand.Although clearly belonging to the genus Macronectes, this species was notably smaller and less robust than either of the modern forms, possibly due to its more ancestral nature or due to the warmer climate of its environment.
The two giant petrel species make up the genus Macronectes. They belong to the order Procellariiformes, the tube-nosed seabirds or petrels. All tube-noses have tubular nostrils, and all those in the family Procellariidae, the true petrels, have their nostrils united along the top of the bill.
