Cape gannet colony, Birds Island, Lamberts Bay, South Africa.
The Cape gannet (Morus capensis) originally Sula 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.
