The documentation form by Jeanne C. Edwards is the only one submitted and forms the basis of this record. | Elimination of similar species: Common Redpoll is similar. But just by looking at the two side by side, the difference overall was very apparent. Looked as tho dusted in white powder, much more white area (e.g. rump + breast + undertail). Not as much streaking. Smaller red cap. | The original documentation form event began around 15:30:00.

The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Other observers include Ken Lowder, Jim Scheib, and John Daniel. | Elimination of similar species: Comparisons to Common Redpoll are made by utilizing the field characteristics described in an article by Czaplak in December, 1995 "Birding". Undertail coverts: This bird showed two very short streaks (almost dots) on longest covert, whereas a Common typically has wide bold streaking. The brightest adult male Commons may have only one medium width streak, but this bird had no red or pink on breast, and so was not an adult male Common. Rump: The rump was white with faint streaking. Most Commons have extensive streaking. Bright adult Commons can have no streaking, but the rump is pinkish-red. Mantle: The ground color of the back of the Common is described as warm brown, or sometimes paler grayish-brown. This bird had grayish feather edgings, with whitish-gray in the middle of the mantle and toward the back. Flank Streaking: Common typically has thick brown streaking. This bird had more wispy gray-brown streaking, which extended back to the base of the tail. Breast and Rump Color: Common has pinkish-red to bright red breast. This bird was buffy under chin, and the rest of the breast was white. Size & Structure: Common has a less bulky neck and greater slope to forehead. This bird has a steep forehead slope and what appeared to be a bulky "no-neck". Bill shape: The bill was short on this bird. The width at the base of the bill appeared to be the same dimension as the length. Common typically has longer bill. Head: This bird showed a buffy wash to the face, sides of the nape, and upper breast, which Common typically does not have. | The original documentation form event lasted from 08:15:00/11:30:00.

Franklin's and Laughing Gull would be larger, darker mantled and have a prominent eye ring. Sabine's Gull would've had a bicolored bill, forked tail and different - white triangular - pattern to its wings. The larger Common Black-headed Gull looks like a larger version of a Bonaparte's Gull with a brownish hood and a red bill. The associated Bonaparte's Gulls were darker mantled and larger. The wings were more angular in appearance with a white leading edge and black wing tips. I have observed all but the Laughing Gull - though the Sabine's Gulls were immature, the distinctive wing pattern is present in both adults and immatures - and feel confident in calling this an adult Little Gull. | The original documentation form event lasted from 10:15:00/10:30:00 and 11:00:00/11:08:00.

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 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.
