The diving-petrels are relatives of the petrels distinguishable only by small differences in plumage and bill construction. They feed on plankton by pursuit diving. Peruvian diving petrel, Pelecanoides garnotii NT; Magellanic diving petrel, Pelecanoides magellani LC; South Georgia diving petrel, Pelecanoides georgicus LC
Most albatrosses and procellariids use two techniques to minimise exertion while flying, namely, dynamic soaring and slope soaring. The albatrosses and giant petrels share a morphological adaptation to aid in flight, a sheet of tendon which locks the wing when fully extended, allowing the wing to be kept up and out without any muscle effort.

This is a list of the bird species recorded on the Auckland Islands .The avifauna of the Auckland Islands include a total of 123 species.. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2022 edition.
Albatrosses and petrels are threatened by introduced species on their breeding islands, pollution, and by being taken as bycatch by longline fisheries, as well as by trawl and gillnet fisheries. The Agreement requires that measures be taken by signatory governments to reduce bycatch; protect breeding colonies ; and control and remove introduced ...
One important step towards protecting albatrosses and other seabirds is the 2001 treaty, the Agreement on the Conservation of Albatrosses and Petrels, which came into force in 2004 and has been ratified by thirteen countries, Argentina, Australia, Brazil, Chile, Ecuador, France, New Zealand, Norway, Peru, South Africa, Spain, the United Kingdom ...
They range in size from the giant petrels with a wingspan of around 2.0 m (6 ft 7 in), that are almost as large as the albatrosses, to the diving petrels with a wingspan of around 34 cm (13 in) that are similar in size to the little auks or dovekies in the family Alcidae. Male and female birds are identical in appearance.
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 ...
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 ...
