The breeding male is patterned grey, with a black rear end, light chestnut wings, and a brilliant white speculum, obvious in flight or at rest. [12] In non-breeding (eclipse) plumage, the drake looks more like the female, but retains the male wing pattern, and is usually greyer above and has less orange on the bill.
The speculum feathers are bright blue with white edges. The speculum is a patch, often distinctly coloured, on the secondary wing feathers, or remiges, of some birds. Examples of the colour(s) of the speculum in a number of ducks are: Common teal and green-winged teal: Iridescent green edged with buff. [1] Blue-winged teal: Iridescent green. [2]

This is supported by the observation that in mallard × American black duck hybrids, females of both taxa prefer the sexually dimorphic mallard drakes over the dull-plumaged black duck drakes; [23] [24] that the green-winged teal is in some aspects—such as the less contrasting nuptial plumage—intermediate between the common and speckled ...
