Blue-winged Teal - Spatula discorsBlue-winged Teals are generally warm-season ducks, usually avoiding cold weather more than many other North American ducks.  They are one of the latest arriving ducks in South Dakota, and one of the first migrants to leave in the fall.  Large numbers may fly non-stop over open ocean to wintering grounds in South America.  Despite the extremely different plumages of the males, Blue-winged Teals have been found to be almost genetically identical to the Cinnamon Teal. Females of the two species are extremely difficult to tell apart.


During the summer breeding season, they are found in and around shallow freshwater ponds and marshes, where water is adjacent to upland grasses and herbaceous vegetation that they use for nesting. In migration they can be found on almost any fresh water habitat, from larger lakes to temporary watered areas like flooded fields and ditches.


Blue-winged Teal primarily eat plant material, including aquatic plants, seeds, and waste grain.  They also eats crustaceans and insects, particularly females during summer breeding season.


Forages in very shallow water, swimming with head submerged or picking items off the surface of the water.  They are often found in small flocks along the water's edge.


Late April through July.  The nest of a Blue-winged Teal is a depression on the ground, lined with grasses and weeds, with a final layer of feathers and down.  The female usually lays 8 to 13 eggs, and the female alone incubates them.  The young leave the nest soon after hatching and find their own food, but the female will tend to them for about 3 weeks.  The young fledge after about 6 weeks.


Quack from females, with squeaky whistles or a louder chyerk from males. 


Winters along southern U.S. coasts and down through Mexico, Central America, and South America.

South Dakota "Hotspot":

When you're out birding, look around. Is there water? Then you're likely in a Blue-winged Teal hotspot! They can be found in pretty much any location where shallow water is found, including the shallow margins of large lakes, wetlands and marshes, flooded fields, and wet ditches.

Similar Species:

Male rather distinctive with face markings, but females are similar in appearance to many duck species. Some identification clues for females are subtle and difficult to see in field conditions. Identification by a nearby male mate is sometimes the safest way to distinguish them.
