Green-winged Teal Anas crecca

All The Birds Of North America: Green-winged Teal Anas crecca

Although primarily a bird of marshes and mud flats, the Green-winged Teal is at home on land; it has even been known to visit upland woods to eat berries, grapes, and acorns. Despite its small size, this species is swift in flight. Green-winged Teals migrate early in spring; from their wintering grounds, they travel north in compact flocks, arriving in northern Alaska by early May.

Identification: 12-16". Small. Breeding drake has chestnut-colored head with bright green patch extending back behind eye; vertical white stripe on side of breast; belly pale whitish; sides gray, wings darker gray. Female, immature, and nonbreeding drake mottled gray and brown, with whitish belly and dark upper wings. All have green speculum.

Green-winged Teal Anas crecca Voice: Drake gives a clear, repeated whistle; female quacks.

Green-winged Teal Anas crecca Voice Habitat: Lake borders, ponds, marshes, and mud flats.

Range: Breeds from N. Alaska south to N. California and Colorado, east to Newfoundland and N. New England. Winters from British Columbia and Utah south, east to Texas; also along Atlantic and Gulf coasts.
