Fairy Prion
Pachyptila turtur

Fairy Prions are small birds (23-28 cm in length) of the same order as albatrosses, petrels and shearwaters. The prions form a group of almost identical birds, all with bluish-grey plumage on the back and wings, a black M shape across the wings and a black tip to the tail. While not the most numerous of the prion species, they are quite common in winter off the Australian coast. They feed on small crustaceans such as krill, although they will occasionally take fish and can be attracted to boats with bait.
