The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Herring Gull eliminated by larger size, lighter mantle color, lack of black and red spots on bill, and wrong leg color (pink, although a very few Herring Gull show yellowish legs). Ring-billed Gull eliminated by smaller size, lighter mantle color, lack of a black ring on bill, and by yellower leg color. | The original documentation form event lasted from 13:13:00/14:08:00.

The documentation form by Jim Bangma and Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Ring-billed is ruled out by the solid gray mantle combined with the extensive molt of the flight feathers. Ring-bills and similar 3 year gulls obtain the gray mantle during a post-juvenal molt. Flight feathers are not molted at this time. Flight feathers are molted after one year, at which time the body of a Ring-bill would be much whiter. Also, the mantle was a much darker shade of gray than any Ring-bill present. Additionally, Ring-billed Gull's bill is proportionally smaller and thinner, with more curve. Herring Gull would be larger. The mantle of a Herring Gull would be paler gray, nearly the same shade as that of the Ring-bills. The bill would be proportionally heavier with a more marked gonydeal angle. Herring Gulls may show a black tipped bill, but the black normally blends into the pink of the base or runs in along the cutting edges of the bill. The bill and legs would be brighter pink. Other similarly sized extralimitals can be ruled out by the mantle color as well as bill pattern and shape. A striking feature of this bird was its leg length. In an effort to better understand this, Bangma paid a visit to the American Museum of Natural History and examined specimens of Herring, Ring-billed and California Gulls. Measurements were made of a representative selection of specimens. The following chart shows the results. [Chart] While there is some overlap between these species, it is interesting to note that the breaking point between California Gull and the other two is very near the ratio of 1.5. While not diagnostic by itself, the length of this bird's tarsus relative to the culmen as estimated by us in the field is indicative of California Gull. | The original documentation form event lasted from 11:00:00/11:40:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Sinclair, Thomas H. Kent, and Jim Fuller were submitted later. | Elimination of similar species: Ring-billed and Herring gulls are the two most likely species of confusion. Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. | The original documentation form event lasted from 10:55:00/12:24:00.

Another observer includes Susan Grove. | Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). | The original documentation form event lasted from 12:30:00/15:30:00.

Bendorf were submitted later. Other observers include Timothy Dwyer, John Cordell, James Huntington, Cal Knight, Bernie Knight, and Rick Hollis. | Elimination of similar species: First-year Ring-billed Gulls were all in first winter plumage with gray mantle and were much lighter overall. The only other species considered is juvenile Herring Gull. The size is small for Herring Gull. The elongated appearance and short legs fit California Gull. Most young Herrings that I see in early fall have mostly dark bills that are larger than that of this bird. The double inner wing bar and lighter tertial tips fit California Gull. The overall relatively uniform and relatively light brown color without windows in the inner primaries also made this bird look different from Herring Gull. | The original documentation form event lasted from 15:15:00/16:55:00 on October 27, 1990 and from 19:10:00/22:30:00 and 15:00:00/16:00:00 on October 28, 1990.

The article by Stephen J. Dinsmore forms the basis of this record. | Elimination of similar species: [...]The bird was similar in size to the largest Ring-billed Gulls, but slightly larger than others. I approached closer and noted that, when compared to a Ring-billed Gull, the bird had duller yellow legs, a stouter bill with black and red spots near the tip of the lower mandible, and a darker gray mantle. [...] The bird was slightly larger than most of the Ring-billed Gulls, although one or two of the biggest Ring-billed Gulls were as large as the bird I was studying. Proportionately, the bird was heavier and larger-headed than a Ring-billed Gull. [...] I estimated the mantle color to be about midway between those of Ring-billed Gull and a Lesser Black-backed Gull. [...] The bill was heavier than the bill of a Ring-billed Gull and had a distinct gonys. The legs were pale gray-green, unlike the bright yellow legs of a Ring-billed Gull. Leg length appeared similar to a Ring-billed Gull. | The original documentation form event lasted from 07:45:00/09:27:00.

The documentation by William and Rebecca Otto is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] We eliminated the possibility of the gull being an immature Bonaparte's gull by the following criterion: 1. Leg color. The gulls legs and feet were entirely black. Bonaparte's gull have reddish legs. This was apparent at great distance on the immature Bonaparte's gulls present. 2. Primary feathers. The gull had black outer primaries and gray inner primaries. Immature Bonaparte's having some obvious white inner primaries.) 3. Behavior. Although this may seem rather unscientific, the gull not joining the groups of feeding or loafing gulls present seems significant to me. | The original documentation form event lasted around 30 minutes.
