Green-winged Teal

North American Green-winged Teal (Anas crecca carolinses)

Green-winged Teal (Anas crecca carolinensis), the smallest species of dabbling duck found in North America, handsomely standing out with contrasting rusty colored head and vivid emerald green facial markings outlined with thin tannish stripe.  Breeding drake green-winged teal small tufts on the backs of their necks. White vertical stripes are visible on the sides of their vermiculated chests. Eurasian, or Common, Green-winged Teal (A. c. crecca) drakes lack this feature but have a horizontal stripe consisting of their tertial feathers. The 2 subspecies otherwise appear identical. Other useful identification characteristics are diagonal creamy stripe on each side of the tail and green specula, which are readily seen in flight. Both sexes have similar gray bills, but the hen displays a lightly lighter shade than the drake and may be mottled. The legs match the somewhat dappled tan plumage on their stomachs.
