The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen. | Elimination of similar species: The shape was obviously that of a grebe. The bird was much too large for a Horned or Eared grebe, both of which were seen within an hour of this sighting. The combination of large size, white throat/cheek patch, and bill size and color eliminates all other grebes. | The original documentation form event lasted from 09:50:00/10:35:00.

The head was also a bit flatter and it rode higher in the water, just giving a different posture than a loon. Plumage details did not fit any loon. Western Grebe- Thicker neck, some color on neck and white cheek eliminated this one Pied-billed Grebe - Size, bill shape, and other features wrong. Horned/Eared Grebes - Although it gave much the same appearance as a horned grebe, size and bill eliminated both. | The original documentation form event lasted from 16:34:00/16:42:00.

Western/Clark's shows white rather than gray on the chin, neck, and breast and is larger. Horned Grebes are smaller and also are white on the underparts. Pied-billed could be eliminated by the size and shape of the bill alone. Although fall Eared Grebes are fairly gray, the size equaling Hooded Mergansers and the large bill allowed me to eliminate that species. | The original documentation form event lasted from 16:30:00/16:40:00.

The bird was obviously larger than a Pied-billed Grebe which would, in addition to the yellow bill, eliminate all but Western Grebe.
