Appearance:

Large dabbling duck. In all plumages distinguished from other dabbling ducks by its slim neck and elegancy. Male with dark brown head, white breast and lower neck, with white wedges extending upwards on side of neck. Long, pin-like tail. Female mostly brown, wattled plumage, with longer tail than other dabbling duck females. Both sexes with bluish bill. Speculum dark green with broad white rear edge. Front edge buff in males. Edges more prominent in flight than the actual speculum. Flight pattern closer to Wigeon than Mallard.

Sound:

Female: similar to Mallards coarse laughing sound, but with a more emphasized first "haaa", and a more silent accelerating subsequent "laugh". Male: Pleasant, resonant "plop" similar to Teal, but lower pitched, richer, mellower and not so metallic. Accompanied by a higher pitched, slightly raspy whistling "aiiooo" rising and falling in pitch.
