I saw these ducks a little removed from a large group of noisy mallards. Throughout the summer I noticed a few pairs of these ducks at the lake. This particular afternoon they were enjoying a solitary swim. Less boisterous than the mallards, the calm water and the muted colours of the late fall seemed made for them. Although the same size and shape as mallards, their colouring makes me think they might be a mix of mallard and American Black Duck.
