The Antarctic prion (Pachyptila desolata) also known as the dove prion, or totorore in Māori, is the largest of the prions,[2] a genus of small petrels of the Southern Ocean.

Taxonomy

The Antarctic prion was

monotypic: no subspecies are recognised.[6]

Prions are members of the

triglycerides that is stored in the proventriculus. This can be sprayed out of their mouths as a defence against predators and as an energy rich food source for chicks and for the adults during their long flights.[9] Finally, they also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.[10]

Description

The Antarctic prion has an overall length of 27 cm (11 in), a wingspan of 61–66 cm (24–26 in) and weighs 150–160 g (5.3–5.6 oz). Like all

coverts are near black. It is so similar in appearance to Salvin's prion that the two species cannot be distinguished at sea.[11]

Distribution and habitat

It breeds in colonies on the Auckland Islands, Heard Island, Macquarie Island, Scott Island, South Georgia and the South Sandwich Islands, the South Orkney Islands, South Shetland Islands, Crozet Islands, and the Kerguelen Islands.[1] When not breeding, it ranges throughout the southern oceans.

Food and feeding

Like all prions, the Antarctic prion eats primarily zooplankton, which it obtains by filtering water through its upper bill.[8]

Breeding

The Antarctic prion nests in

incubating the single egg and raising the chick.[8]

Conservation

The Antarctic prion has an occurrence range of 76,600,000 km2 (29,600,000 sq mi) and an estimated adult bird population of 50 million.[1][12]
