White-Headed Duck
Oxyura leucocephala
The White-headed Duck is a compact stiff-tailed diving duck of lakes and ponds in Spain, North Africa and western to central Asia. Males have a white face, black cap and neck and a swollen, bright blue bill, while females are browner with a striped face. It has declined sharply and is Endangered, mainly from habitat loss and pollution, and in Europe also from hybridisation with introduced Ruddy Ducks.
Did you know?
- When threatened it usually paddles away rather than flying.
- Its hybrids with Ruddy Ducks are fully fertile, threatening its genetic integrity.
