The documentation form by Brian Blevins is the only one submitted and forms the basis of this record. Another observer was Lewis Blevins. | Elimination of similar species: Summer, Scarlet, Western Tanager. Scarlet Tanager was eliminated by the lack of dark wing and the orange-green instead of yellow-green. Western Tanager was eliminated by the lack of wing bars. Summer Tanager: this was the closest of the three especially considering the cooperi form found in the southwest. The large bill in common to both species if we consider the cooper form of the summer, however, the color of the mandible overall more dark than light lends the pull towards hepatic. The dark, brown orange-green also pulled me over to the hepatics in respect to the ones I have observed in Arizona. Call note also differs. | The original documentation form event lasted from 13:15:00/14:20:00.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: The body and bill structure eliminated all but hooded gulls and the brown plumage indicated a first year bird. Size close to Ring-billed, in addition to plumage already described, eliminated some of the smaller hooded gulls. The most likely candidate for confusion would be the Franklin's Gull. Juvenile Franklin's shows a hooded pattern early in development rather than a brown wash on the head. Franklin's tail band would also be incomplete with white feathers showing on the outer edge. It would also show fewer dark primaries, with the inner flight feathers more approximating the mantle and inner wing color. No other small gull has this characteristic. | The original documentation form event lasted from 11:45:00/12:10:00 and 15:30:00/14:00:00 [sic].
