The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Francis Moore and Dick Kraemer. | Elimination of similar species: [...] There were many first year Herrings that were darker with dark wingtips. We also saw, but not at same time, a larger, slightly lighter gull without tail band that we identified as a first year Glaucous Gull. It was consistently larger than Herring and heavier bodied. Uniform color, white flight feathers from below separate bird from Herring. Size and tail band separate from Glaucous. | The original documentation form event lasted from 10:15:00/10:45:00.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Louise Augustine and Dick Tetrault. | Elimination of similar species: The juvenile bird is distinctive and I was able to pick it out quickly. When we first saw the second-year bird, we considered both Franklin's and Laughing gulls. A juvenile or first-winter Franklin's would not have uniform gray in the wing coverts. A second-summer or second-winter Franklin's Gull would not have a full tail band. The bill shape also favors Laughing Gull. The bird appears to be in second-winter plumage, except for the tail band which fits better with first-summer plumage. I was impressed with the soft grayness of the bird and its similarity the birds I photographed recently in North Carolina. | The original documentation form event lasted from 09:30:00/11:15:00.

The documentation form by Thomas Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller were submitted later. | Elimination of similar species: We based our identification on size, small uniform bill, lack of white around and in front of the eye, sharp separation of light and dark on the neck, and fine chin strap. The bird was too bulky for a Red-throated Loon and did not have a very thin, upward pointing bill. We were more concerned about excluding Common Loon. The Common Loons we saw later at Rathbun Reservoir had white around the eye, more irregular and less distinct separation of light and dark on the neck, and much more massive bills with bulbous thickening near the tip. | The original documentation form event lasted from 07:25:00/07:40:00.

If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

The documentation form by Tim Schantz is the earliest and the one that forms the basis of this record. Other documentation forms by Maridel Jackson, Ross Silcock, Jane R. Clark, and Jim Sinclair were submitted later. Other observers include John Cecil, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: Northern Goshawk- Although Goshawks have been known to show pointed wings, they are never as pointed as a Falcon's. I have seen many Northern Goshawks and jizz alone would rule this one out. I saw no barring on the tail. One of the prime field marks on a Goshawk are the bright white undertail coverts which this bird did not have. The bird in question also lacked a dark crown. Peregrine Falcon- Size. No dark helmet. Jizz (mentioned above). The bird lacked overall contrast of a Peregrine Falcon. Juveniles would be brown. Prairie Falcon- Color. Prairies are a brown bird in all plumages. The underwing was uniform with no black axillaries. Habitat. Prairies feed almost exclusively on small mammals. | The original documentation form event occurred around 15:30:00.
