Subspecies
Although Anas crecca was split by Sangster et al. (2001) into Common Teal (Anas crecca) and Green-winged Teal (Anas carolinensis) and this treatment was followed in BirdLife International (2004), AOU (1998) do not adopt this treatment and this source is now followed here.
Considered by some authors to be a subspecies of Common Teal (Anas crecca).
