Cape Gannet

The Cape gannet (Morus capensis) is a large seabird of the gannet family, Sulidae. They are easily identified by their large size, black and white plumage and distinctive yellow crown and hindneck. The pale blue bill is pointed with fine serrations near the tip; perhaps because of the depth and speed of the gannet's dive when fishing (depending on altitude, gannets hit the water at speeds of between 40 and 120 km/h (25 and 75 mph)), its beak has no external nostrils into which the water might be forced. The Cape gannet is identified from the Australasian gannet by the all-black tail, a longer black stripe down the throat (from underneath the beak) and more extensive black on the face, but all of these features are difficult to identify unless at close proximity. The Cape gannet is also very similar to the northern gannet, but the latter differs from its entirely white tail and its wings, which are only black at the tip. It also is similar to the blue-footed booby (Sula nebouxii).
