| Occurrence Remarks |
The documentation form by John Van Dyk is the only one submitted and forms the basis of this record. | Elimination of similar species: I rule out any possible confusions, as follows: - White-winged Scoter has white in the wing and lacks sharp contrast between crown and face - Black Scoter has rounded forehead and lacks pale head patches - Ruddy Duck is smaller, has differently shaped bill and dark line across cheek - Female Scaups have white in the wing, differently shaped white patch at base of bill, and little contrast between crown and face. | The original documentation form event occurred for around 20 minutes. |
