Blue-winged Teal--Anas discors

Male Blue-winged Teal

With a North American population of 6.6 million for 2008, the Blue-winged Teal population is moving in the right direction. Teals are ducks who are smaller than the average. Other teals in Orange County include the Cinnamon Teals and Green-winged Teals. Blue-winged Teals have been known to hybridize with Cinnamon Teals, and Northern Shovelers. Blue-winged Teals prefer shallow water and can be found at Upper Newport Bay Ecological Reserve, Bolsa Chica Ecological Reserve, and other similar Orange County environments.

Male and female Blue-winged Teal.

Blue-winged Teals have the diagnostic vertical crescent on each side of the face just behind the bill. The blue patch for which they are named is on the shoulder and only visible if they stretch out their wings or fly. Both male and female are finely patterned with a brownish color over most of their body. Females look very similar to the female Cinnamon Teals and have a broken white eye-ring and white at the base of the bill and otherwise are brown. They can be found from Alaska to South America. Like all teals, it is a dabbling duck. It inhabits ponds and wetlands eating aquatic plants and seeds, and aquatic invertebrates.

The Blue-winged teal winters in Orange County and areas south. It breeds in Canada and Alaska and the Midwest.

Blue-winged Teals can be found hanging out with other ducks at wetlands and ponds. Usually you will see mixed flocks of Cinnamon Teals, Green-winged Teals, Northern Pintails, Scaups, and Mallards. You won't see them at community parks. These are wilder ducks.

When you are out birding in the fall and winter, and even the very beginning of spring, look for the Blue-winged Teal.

Journal article on a hybrid Blue-winged Teal and Northern Shoveler.

Great site. Very good videos. Check out the high quality videos at the IBC. Seeing the bird in action really helps a birder identify the species in the field.
