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.

fulmar prion
The fulmar prion (''Pachyptila crassirostris'') is a species of seabird in the family Procellariidae, found in the southern oceans.
Etymology
Its common name " prion" (not to be confused with the misfolded proteins of the same name) means "saw ...
(''Pachyptila crassirostris''); the two species cannot be distinguished at sea.
Distribution and habitat
The fairy prion is found throughout oceans and coastal areas in the
Southern Hemisphere.
[Harrison, C. & Greensmith, A. (1993)]
Behaviour
Food and feeding
The diet consists mainly of planktonic crustaceans and tiny fish, which they catch by either seizing prey while on the surface or by dipping their bill into the water while in flight.
Breeding
They breed colonially and prefer small islands. The nest is situated in soil, hidden by vegetation and is dug with the bill or feet, or it is in a hollow in a crevice. When coming back to their nest at night, they will coo softly and listen for their mate.
Conservation
Widespread and common throughout its large range, with an estimated population of 5,000,000, the fairy prion is evaluated as least concern on the IUCN Red List of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biologi ...
