Blue petrel
The blue petrel (''Halobaena caerulea'') is a small seabird in the family ''Procellariidae''. This small petrel is the only member of the genus ''Halobaena'' but is closely allied to the prions.〔ZipCode Zoo (16 Jul 2009)〕
==Taxonomy==
The blue petrel is the only bird from the genus ''Halobaena'', and a member of the Procellariiformes order. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. The bills of Procellariiformes are 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.〔Double, M. C. (2003)〕 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.〔Ehrlich, Paul R. (1988)〕
The word "petrel" is derived from Saint Peter and the story of his walking on water. This is in reference to the petrel's habit of appearing to run on the water to take off.〔Gotch, A. T. (1995)〕
