Dabbling Duck Dabbling ducks are easily recognizable by their trait of sticking their rump out of the water while they feed. The ancestor of the great apes was an arboreal climber. Southern resident species typically show less sexual dimorphism, although there are exceptions such as the paradise shelduck of New Zealand, which is both strikingly sexually dimorphic and in which the female's plumage is brighter than that of the male.

Ducks with more webbing were better at eating aquatic plants than ducks with less webbing, so the ducks with more webbing survived and reproduced better than ducks with less webbing.
