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.
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. [48]
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.
The islands hold important seabird breeding colonies, among them albatrosses, penguins and several small petrels, [6] with a million pairs of sooty shearwater. Landbirds include red-fronted and yellow-crowned parakeet , New Zealand falcon , tūī , bellbirds , pipits , and an endemic subspecies of tomtit .
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 ...

Light-mantled Sooty Albatross. The light-mantled albatross population is estimated at 58,000, from a 1998 estimate, and is declining. [9] Threats and population status are poorly quantified and the species is classified as near threatened, [1] [12] with an occurrence range of 44,300,000 km 2 (17,100,000 sq mi). [9]
Petrels are a monophyletic [1] group of marine seabirds, sharing a characteristic of a nostril arrangement that results in the name "tubenoses". [2] 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 ...
