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. 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. 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.
