Mallard

Anas platyrhynchos

Also called wild duck, greenhead.

The ancestor of nearly every domestic duck, which is why park ducks are so variable. The blue speculum bordered with white on both edges is present on every mallard regardless of how odd the rest looks.

  • Female: mottled brown with an orange bill blotched with black.
