Eurasian Teal look-alikes

Key differences

The Green-winged Teal (formerly considered a subspecies of Eurasian Teal) is found in North America. Males differ by having a vertical white stripe on the side of the breast (absent in Eurasian Teal) and a less prominent white border to the green eye-patch. Females are virtually indistinguishable in the field without very close observation or genetic analysis.

Key differences

Garganey males have a prominent white supercilium (eyebrow stripe) and a grey body, lacking the green head patch of the Teal. Females are more similar to female Teal but generally have a more distinct pale supercilium and a darker eye-stripe. Garganey also have a larger, greyer bill.

Key differences

Female Mallards are significantly larger than Teal. While also mottled brown, they lack the distinct green speculum bordered by white (Mallard speculum is blue-purple with white borders) and have a larger, orange-tinged bill.
