Diving ducks mainly feed by diving beneath the surface of the water, they are mostly gregarious and mainly found on fresh water and estuaries. They are strong fliers but have difficulty taking off, having to run across the water to gain take off speed. Diving ducks have their legs further back on their bodies than dabbling ducks to help propel them when underwater, though this restricts their ability to walk on land.


RED-CRESTED POCHARD (Netta rufina)

The Red-Crested Pochard is a diving duck from southern Europe and central Asia.
It is a gregarious bird forming large flocks in winter and often mix with other diving ducks such as the Common Pochard. A feral population of Red Crested Pochard has been established in the United Kingdom which have more than likely formed from escapees.

Adult male Redhead in alternate plumage easily is distinguished from Canvasback by yellow eye, blue bill with black tip, gray back and different profile. Females distinguished from female Canvasback by brown body plumage and blue bill with black tip. Females can be distinguished from female Ring-necked Duck by smoothly rounded crown, dark cap and darker brown plumage.


COMMON POCHARD (Aythya ferina)

In winter and spring, male pochards are very distinctive. They have a bright reddish-brown head, a black breast and tail and a pale grey body. Females are more easily confused with other species; they are brown with a greyish body and pale cheeks. However, during the ‘eclipse’ – when ducks grow new feathers – the males look very similar to the females. They become more camouflaged so that they don’t draw the attention of predators.


TUFTED DUCK (Aythya fuligula)

Our commonest diving duck, nesting on flooded gravel pits and lakes and reservoirs, and gathering in large flocks in the winter, often mixed with Pochard and Coot. Tufted Ducks feed on waterweed, plant seeds and aquatic invertebrates.
