Mallard

Preening Mallard (Enlarge)

Photographed in the campus of the University of Reading, Berkshire, UK, in August 2006.

The mallard (Anas platyrhynchos), or wild duck, is the most common duck species in sub-tropical America, Europe, Asia, New Zealand and Australia. It is the ancestor of all domestic ducks, and so can interbreed with them all.
