Adult in alternate plumage is unmistakable. Female, immature and eclipse male similar to Green-winged and Cinnamon Teals. Note the small size and small bill of the Green-winged Teals as well as the green speculum. Cinnamon Teal is very difficult to distinguish in some (female) plumages, but note the smaller bill without a spatulate tip and the more distinct facial pattern (pale loral spot and more distinct eye line) of the Blue-winged Teal.
