Mallard
Dabbling duck which feeds in shallow water, along the surface or by tipping headfirst into the water to graze on aquatic plants, vegetation, insects, and larvae.
Males, called drakes, have glossy green heads. Females, called hens or ducks, are mainly brown.
This species is the main ancestor to most breeds of domesticated ducks.
Ducklings are fully capable of swimming as soon as they hatch.
Very adaptable species, being able to live and even thrive in urban areas which may have supported more localized, sensitive species of waterfowl before development.
