Another documentation form by Ann Johnson was submitted later. | Elimination of similar species: Double-crested is smaller, with a much thinner neck. There is a noticeable transition from the thin neck to the larger head. In this bird, there was no noticeable widening from the neck to the head. Additionally, Double-crested has a proportionally much smaller and weaker bill. Double-crested's forehead slopes more evenly into the bill. While these differences may be difficult to see in single birds without comparative experience, in direct comparison they are significant. Additionally, the orange facial skin combines with the gular pouch to accentuate the overall orange color of the face. Other extralimital black cormorants can be ruled out on size alone, additionally, most have thinner necks and smaller bills than even Double-crested. | The original documentation form event lasted from 11:00:00/11:02:00.

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 Jim and Karole Fuller is the only one submitted and forms the basis of this record. | Elimination of similar species: All other adult dark mantled gulls have pink legs, except the Yellow-footed gull which is seen at the Salton Sea, and extreme southwest California. That bird has never been seen away from that area, and should be noticeably larger than a Lesser black backed gull. The European race of the Herring gull has yellow legs, and one has been seen on the east coast the past two winters. That bird should be larger, and does not have a dark mantle. | The original documentation form event lasted from 14:03:00/14:27:00.
