The Green-winged Teal is the smallest of the group known as dabbling ducks, which typically feed by tilting head-first into shallow water while foraging for seeds of aquatic plants as well as aquatic invertebrates. Male Green-winged Teal pair up with females during the winter, but depart once incubation begins.
The female Green-winged Teal usually lays one egg per day until her clutch is complete. At that time, she removes down from her breast to better insulate the eggs, and begins incubation. Although the young ducklings are able to feed themselves, the female broods them at night and during cold weather until they are larger.
