The southern giant petrel is slightly larger than the northern giant petrel, at 3 to 8 kg (6.6–17.6 lb), 180 to 210 cm (71–83 in) across the wings, and 86 to 100 cm (34–39 in) of body length. [ 2 ] [ 11 ] The northern giant petrel is 3 to 5 kg (6.6–11.0 lb), 150 to 210 cm (59–83 in) across the wings and 80 to 95 cm (31–37 in) of ...
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
The northern giant petrel (Macronectes halli), also known as Hall's giant petrel, is a large, predatory seabird of the southern oceans. Its range overlaps broadly with the range of the related southern giant petrel ( Macronectes giganteus ), albeit slightly further to the north.
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 ...
Some of the larger petrels have to nest on windswept locations as they require wind to take off and forage for food. [27] Within the colonies, pairs defend usually small territories (the giant petrels and some albatrosses can have very large territories) which is the small area around either the nest or a burrow. Competition between pairs can ...
The word petrel (first recorded in that spelling 1703) comes from earlier (ca. 1670) pitteral; the English explorer William Dampier wrote the bird was so called from its way of flying with its feet just skimming the surface of the water, recalling Saint Peter's walk on the sea of Galilee (Matthew xiv.28); if so, it likely was formed in English as a diminutive of Peter (< Old French: Peterelle ...
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 ...
Based on Austin (1996), Bretagnolle et al. (1998), Nunn & Stanley (1998) and Brooke (2004), several changes have been made from the more traditional taxonomy. The two species in the genus Bulweria are no longer considered close to the rest of the gadfly petrels; several more gadfly petrels are removed from Pterodroma and placed in Pseudobulweria (allied to the shearwaters), and the Kerguelen ...
