There are about sixteen species of Diving Duck (Subfamily: Aythyinae) including the Canvasback, Ferruginous Duck, Hardhead, Marbled Duck, Pochard (Baer's, Common, Madagascar, Red-crested, and Southern), Redhead, Ring-necked Duck, Rosybill, Scaup (Greater, Lesser, and New Zealand), and the Tufted Duck.
These ducks mainly feed by diving underwater for their food on fresh water lakes or on estuaries. Their feet are placed further back on their body, compared to a dabbling duck, giving them more efficient propulsion on and under the water, which makes them better swimmers, and divers. However, this means diving ducks find it harder to walk on land, and can be seen to shuffle along clumsily with an upright stance trying to maintain their balance.
The male Ringed-neck Duck, Tufted Duck, Greater and Lesser Scaups can all look very similar but the Tufted Duck has a distinctive long tuft on its head, the Ring-necked Duck has a distinctive white line around the base of the beak which is grey-blue with a broad white band and black tip. The Greater Scaup is larger and more bulky than the Lesser Scaup which has a slightly broader beak giving it the nickname 'Broadbill'. More information can be found

The male Canvasback, Common Pochard, and Redhead also look very similar at first glance but the Redhead is the only one with yellow eyes and a bluish-grey beak with black tip. The Canvasback has a relatively long all-black sloping beak with red eyes, and the Common Pochard has a dark grey beak with a central band of light-grey and black tip and also has red eyes.
