Ruddy duck - Oxyura jamaicensis
Pairi Daiza, Aug 2014.
Interesting fact:
Relative to body size of the female they lay the largest eggs of all duck species, and this is thought to be meant to maximize survival of the already large youngs which are, as most ducks, nidifugous.

The ruddy duck is a duck from North America and the Andes Mountains of South America, one of the stiff-tailed ducks.
