| | The Ring-Necked Duck (Site not responding. Last check: 2007-10-06) |
 | | In shape, the Tufted Duck, or Ring-bill, as it is called in Kentucky, resembles the Scaup or Flocking Fowl, but is plumper and more rounded. |
 | | The bill of the Scaup Duck is still broader towards the end, with a much narrower unguis, and the flattened part of the upper mandible still narrower than in the Tufted Duck; the colour of the speculum is also different, being bluish-grey in the Ring-necked Duck, and white in the two allied species. |
 | | The females of the Ring-necked and Scaup Ducks, which are nearly similar in colour, differ in the speculum, and in the peculiar form of the bill. |
