Cape gannet
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 kilometres per hour 〔()〕), its beak has no external nostrils into which the water might be forced.
==Morphology==
When seen in flight the snow-white body with the black tail, primaries and secondaries, and dark bill makes them easy to identify. At closer range the distinctive golden crown and nape, which gradually becomes white on the neck, is noticeable. Juveniles and immatures are dark brown with a pale bill, and can resemble the dark-coloured boobies at first glance. Adults are about 84–94 cm (33–37 in) long and have a 171–185 cm (68–73 in) wingspan and weigh ''ca.'' 2600 g (5.7 lbs).
