Pachyptila, the word, comes from the Greek words pakhus and ptilon. Pakhus means thick or stout and ptilon means a feather. Also from the Greek language, Prion comes from the word priōn meaning a saw, which is in reference to its serrated edges of its bill.
All the members of this genus, along with the rest of the Procellariiformes, share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the Albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights. 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.
- Pachyptila turtur, Fairy Prion, breeds on subtropical and subantarctic islands
- Pachyptila belcheri, Slender-billed Prion, breeds on Crozet Islands, Kerguelen Islands, Falkland Islands, and Noir Island
- Pachyptila crassirostris, Fulmar Prion
- Pachyptila vittata, Broad-billed Prion, breeds on islands near New Zealand and the Tristan da Cunha group
- Pachyptila desolata, Antarctic Prion
- Pachyptila salvini, Salvin's Prion
The members of this genus primarily eat zooplankton by filtering water through their upper bill. Some even hydroplane, a technique where they filter food out while flying with their bill in the ocean. They breed colonially, and do so neat the ocean, usually with the same mate for life. Both sexes help incubate the egg, and care for the chick.
Range and habitat
They are pelagic and seldom come to land, except to breed. Also, they all stay in the Southern Hemisphere, and breed on subantarctic islands except the Fairy Prion which breeds on subtropical islands.
