Ring-billed Gull was eliminated on the basis of the darker mantle and upperwings, large, dark eye, and bill color and shape. | The original documentation form event lasted from 15:30:00/16:40:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by James J. Dinsmore was submitted later. | Elimination of similar species: The dark coloration, gull-like shape, and white color in the primary shafts identified both birds as jaegers. Initially, I thought the bird I saw on the 10th was a Parasitic, mainly because of the size and seemingly bright, rust-colored underparts. However, better viewing conditions later showed that the underparts were instead a pale brown color and lacked any hint of rusty color. Long-tailed Jaeger was easily eliminated by size, shape of the central rectrices, and the greater amount of white in the wing. Parasitic Jaeger was more difficult to rule out. The combination of size, wing shape, amount of white in the wing, shape of the central rectrices, and bill size was used to rule out juvenile Parasitic Jaeger. | The original documentation form event lasted from 09:35:00/12:33:00 on November 10, 1996 and 10:55:00/16:05:00 on November 11, 1996.

Another observer includes Chuck Fuller. | Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). | The original documentation form event lasted from 11:30:00/13:10:00.

Red-necked Phalarope (which would be even more unusual at this date) was eliminated by bill size and shape and unstreaked mantle. | The original documentation form event lasted from 09:35:00/10:15:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Cormorants are the only birds likely to be confused with an Anhinga. I have seen thousands of Double-crested Cormorants and I have never seen one soar in this manner. Also, a Double-created Cormorant has a neck which is always longer than the tail (in flight) and looks conspicuously large-headed and thick-necked when seen overhead. Neotropic Cormorant is much smaller and, although it is longer-tailed than a Double-crested, the tail is still shorter than the neck in flight. | The original documentation form event lasted from 16:42:00/16:50:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Franklin's Gull is the only species this bird was likely to be confused with. The larger size, longer, more pointed wings, lack of white color in the primaries, longer, larger bill, dark legs and bill, and gray wash on nape (rather than a more distinct half-hood) are sufficient to eliminate Franklin's Gull. | The original documentation form event lasted from 16:05:00/16:30:00 on July 8, 1994 and 06:15:00/06:28:00 on July 9, 1994.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The bird was clearly one of the "hooded" gulls. The combination of size, mantle color, and upperwing pattern eliminates all of the hooded gulls except for Franklin's Gull. The larger size, less obvious white eye crescents, larger and longer bill, and extensively dark tips to the underwings eliminated Franklin's Gull. | The original documentation form event lasted from 12:45:00/13:10:00.
