Green-winged Teal

Anas crecca

A small, common, fast-flying dabbling duck, often forming tight compact flocks as they wheel and turn in unison.  Green-winged Teal tolerate cold weather better than other teal, and can thus be found further north in the winter.  

Habitat: Marshes and shallow ponds and lakes in the breeding season.  Found in similar habitats during winter and in migration, but can also be found in shallow coastal bays and estuaries.

Diet: Primarily feeds on plant material, including seeds, grasses, and aquatic plants.  Also will eat insects, crustaceans, and mollusks.

Behavior: Usually travels in small flocks, although at major migration stopovers, flocks may number in the thousands.  They rest out of the water more than many ducks, and can sometimes be found on low-hanging branches and logs.  Foraging is primarily by upending in shallow water, filtering mud through the bill, and by picking items from the water's surface.

Nesting: Late May and June
