觀察細節
This individual was observed for over two hours followed by the male redhead (see photos above). I suspect the bird is a hybrid: the rounded head shape is not typical for a female Ring-necked Duck; also missing is what Sibley (2003) refers to as a "faint pale 'spur'". Other wise the contrasting browns on the back and flanks are consistent with a female Ring-necked Duck.
