[...] There was no question in my mind but that he was a thrush, but I thought this bird more brown on his back than I remembered Gray-cheeked to be. I considered Veery, but stayed with my original call. | The original documentation form event occurred from approximately 09:45:00/09:45:15.

[...] In general size, this bird appeared almost twice the size of the Ring-billed Gulls, and considerably larger than the Herring Gulls, maybe 25%. It also had a massive bill compared to either of those species. [...] The legs were a dull gray-pink, and they were noticeably thicker than those of the Herring or Ring-billed Gulls. | The original documentation form event lasted from 11:05:00/11:35:00.

The documentation form by Jim Bangma is the earliest and the one that forms the basis of this record. 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.
