Baikal Teal is a small East Asian duck and a rare wild visitor to the United States. Males have a patterned pale yellowish-brown and green face, while females are brown with a white spot at the base of the bill. Some U.S. sightings may involve escaped captive birds.

The male Green-winged Teal (Anas crecca) has a chestnut head with one broad green sweep behind the eye, rather than the Baikal Teal’s patterned buff-and-green face. On females, look for the Baikal Teal’s white spot beside the bill.
Why they get mixed upBoth are small teals, and brown females can be hard to separate.
