| Occurrence Remarks |
The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Jim Sinclair. | Elimination of similar species: The size and longer, thicker bill eliminate Horned and Eared Grebes. The bird was not large enough to be a W. Grebe. The white on the leading edge of the wing and long neck also eliminate loons, and W. or Clark's Grebe. | The original documentation form event lasted from 10:30:00/10:40:00. |

Viewing Conditions: The sun was overhead and the sky was mostly overcast so the light was O.K. Estimated viewing distance was 200+ yards. I used a B&L 20x spotting scope |
