The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Loon were eliminated because, although the neck was somewhat thick, it was longer than a loon. 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.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Loons were eliminated on the basis of thin neck and posture. Cormorants were eliminated because of straight posture, lack of throat patch, and basic plumage configurations. 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.

The golden yellow cap reminded me of a chestnut-sided but the lack of streaking on the back and absence of any markings on the side eliminated this bird also.

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.

Bonaparte's, Ross', Com. Black-headed, Little and Sabine's gulls could all be eliminated by the presence of the collar.

Although there was a similarity of head profile to the Common Eider, the facial spots eliminated any eider. Black Scoter would have a more rounded head with a uniform lighter cheek area as opposed to the spots on this bird. White-winged Scoter should have shown more rounded angle form the top of the head to the bill, generally would have less distinct facial spots, and definitely would have had white wing patches when the bird raised its wings. | The original documentation form event lasted from 09:50:00/10:05:00.

The documentation form by Babs and Loren Padelford forms the basis of this record. Other documentation forms by Ross Silcock, Duane E. Bright, Stephen J. Dinsmore, and Jerry Probst and Bill Huser were submitted. Other observers include Gordon Brown, Sandra Kovanda, Jim Kovanda, R. Craig Hensley, and other unidentified observers. | Elimination of similar species: [...] Since it was the only gull on the lake, the only birds to compare it with were Ruddy Ducks which appeared smaller and a drake Common Merganser which was larger than the gull. | The original documentation form event lasted from 10:30:00/11:00:00 and 15:15:00/16:15:00.
