Rare and Endangered Animals of Armenia

The White-headed Duck

File:200px-White-headed.duck.jpg The White-headed Duck (Oxyura leucocephala) is a small stiff-tailed duck.

Adult males have a grey and reddish body, a blue bill and a largely white head with a black cap and neck. Adult females have a grey-brown body with a white face and a darker bill, cap and a cheek stripe.

This duck breeds in Spain and North Africa, with a larger population in western and central Asia. Their breeding habitat is large tracts of open water with dense stands of aquatic plants to provide cover and nesting sites.

These birds dive and swim underwater. They are omnivorous, with vegetable matter predominating. They are reluctant to fly, preferring to swim for cover.

This duck is considered endangered due to a large reduction in populations in the last ten years. Most of this decline is due to habitat loss and hunting, but interbreeding of the Spanish population with the introduced Ruddy Duck (Oxyura jamaicensis) is a more recent threat. This has led to the attempted eradication of the American species from western Europe.
