Green-winged Teal--Anas crecca

Green-winged Teal at Upper Newport Bay

Like the American Wigeon, the Green-winged Teal has a green stripe through its eye. It is the smallest dabbling duck in Orange County. According to the Natural History of Waterfowl by Frank S. Todd, the word teal may derive from words in medieval English and or Old Dutch meaning "small." It is true that teals are all small birds. The Green-winged Teal's most easily seen field marks are the chestnut head, the iridescent green stripe on on the side of the head, and the vertical, thin, white stripe down the male Green-winged Teal's side, and the dark bill.

Green-winged Teals eat a variety of aquatic foods, including aquatic invertebrates, aquatic vegetation, and aquatic plant seeds. They prefer shallow ponds or other shallow bodies of water. They can be found in either fresh or salt water.

I have seen Green-winged Teals at Bolsa Chica Ecological Reserve and at San Joaquin Wildlife Reserve. They would also be at other wetlands in the area. I have never seen them at community parks.






Male and female Green-winged Teal

Very few Green-winged Teals breed outside of Canada. The male and female pair up before they migrate to the breeding grounds.

The Green-winged Teal population is increasing despite being the second most hunted duck in the United States. Animal Diversity Web believes it is due in part to the inaccessibility of their breeding grounds.

Green-winged Teals are very easy to spot. When you are out birding wetlands, or shallow water areas, look for the duck with the rich red-brown head and the bright green stripe on the side of its head. The vertical white stripe on the side is another easy field mark. Enjoy watching the Green-winged Teal in Orange County.
