Blue petrel

The blue petrel or blue Prion ( Halobaena caerulea ) is a small marine bird of the family of the Procellariidae , the only one representing kind Halobaena , however very near to the let us request. Its plumage is gray with the white lower part; the bird is distinguished from request by a smaller Bec and by a tail with the white end.

Like all procellaridés, the blue petrels nest in large colonies which they join at the night to avoid the predation of the Skua S. the females deposit at the bottom of a burrow a single egg brooded by the two parents during approximately 50 days. The chick develops and émancipe at the end of 55 days. The colonies of blue petrels meet on almost all the sub-antarctic islands.

It is a circumpolar species which feeds close to the polar face the Antarctic. At sea the blue petrels circulate thus largely between the Australia, the south of the Africa or the America and the Antarctic. They nourish mainly Krill, but also sometimes of other shellfish, Poisson S or Calmar S which it can go to fish while plunging at least up to 6 meters of depth.
