The broad-billed prion (Pachyptila vittata) is a small seabird, but the largest prion, with grey upperparts plumage, and white underparts. It has many other names that have been used such as blue-billed dove-petrel, broad-billed dove-petrel, long-billed prion, common prion, icebird, and whalebird.
The broad-billed prion is a member of the Pachyptila genus, and along with the blue petrel makes up the prions. They in turn are members of the Procellariidae family, and the Procellariiformes order. The prions are small and typically eat just zooplankton; however as a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the prion are on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. They produce a stomach oil made up of wax esters and 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. 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, 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.
