Description:

The Cape petrel(Daption capense), also called the Cape pigeon, Pintado petrel, or Cape fulmar, is a common seabirdof the Southern Ocean from the family Procellariidae. It is the only member of the genus Daption, and is allied to the fulmarine petrels, and the giant petrels. They are extremely common seabirds with an estimated population of around 2 million.

The Cape petrel is the only known member of the genus Daption and is in turn a member of the family Procellariidae and order Procellariiformes. There appears to be a subgroup within the family consisting of the giant petrels, the members of Fulmarus, the Antarctic petrel, and the snow petrel.

All Procellariiformes share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This can be sprayed out of their mouths as a defence against predators and as an energy rich food source for chicks and for the adults during their long flights. 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.

The Cape petrel is a unique looking petrel. It has a black head and neck, and a white belly, breast, and its underwing is white with a black border. Its back, and upperwings are black and white speckled, as is its tail which also has a band of black. When fully grown, their wings span 86 cm (34 in)and they are 39 cm (15 in) long.
