The documentation form by Richard Hollis is the only one submitted and forms the basis of this record. Other observers include Jim Fuller and Carol Thompson. | Elimination of similar species: After ruling out Horned & Eared Grebes due to bill size & color & shape the only possibilities for this bird are Western Grebe and smaller loons. 1. Red-throated loon seems ruled out by shape of bill. 2. In fact all loons & W. Grebe seem ruled out by bicolored bill. 3. Posture & Build were slimmer than most loons I've seen. 4. Neck which definitely was grey (in past) all the way around in front also seems to rule out there. I am puzzled by 2 things & although I'm sure it is a RN Grebe I wonder if it is in some intermediate plummage [sic]. 1 White patch at waterline in front. I saw this distinctly & sketched it on 11/9 as well as on a brief look at the bird on 11/16. 2 Dark cap seems to extend farther down the head than any of the plates would lead me to expect. | The original documentation form event lasted from 07:45:00/08:15:00.

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.

The bird was obviously larger than a Pied-billed Grebe which would, in addition to the yellow bill, eliminate all but Western Grebe. Western Grebe would have looked much larger than the various waterfowl nearby and would not have shown any rust color on the neck. | The original documentation form event lasted from 12:45:00/13:05:00.

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 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 large size and bill color and size all eliminate other grebes. Note that we had just seen another Red-necked Grebe on nearby Big Creek L. 2 hours earlier. | The original documentation form event lasted from 12:05:00/12:40:00.
