Fun Facts

The green wing teal is the smallest dabbling duck native to America.

It is among the fastest fliers of the game birds, capable of flying 97 kph (60 mph) but usually flies 80 kph (50 mph).

These ducks travel in a tight "V" formation at high speeds.

Teals are good swimmers and divers. However, they rarely dive for food, rather they dive to hide from a predator.

These ducks are very active on foot, walking and running for long distances.

Teals have one of the most elaborate mating dances of all Anas species.

Ecology and Conservation

Green wing teals are the second most commonly hunted duck in North America (first are mallards), which places pressure on their populations.

Their wintering habitat has declined due to human population increase. However, teal populations still remain strong and are in fact increasing. Researchers believe this is due to the inaccessibility of their breeding habitat to humans, which is deep in the wilderness. The wetlands that they inhabit in the winter are being managed, more for waterfowl in general, than for the green wing teal.
