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.

Other observers include Dick Tetrault, Chuck Fuller, and Tim Schantz. | Elimination of similar species: The Records Committee has not accepted two previous records of Fish Crow along the Mississippi River in Louisa County because of the difficulty in substantiating the identification. I was well aware of this, and like other committee members, I believed that they were likely present in this area. I can only say that I was watching the birds when I heard them, which eliminates the possibility that they were young American Crows. I would not want to rely on the morphologic features. I was impressed that this group stayed together in the flooded woods, which was unlike the behavior of the American Crows. | The original documentation form event lasted from 08:40:00/09:30:00 and 10:25:00/10:35:00.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller. | Elimination of similar species: Smaller and slimmer than Common, smaller bill. I could not see whether the eye was in the dark or light part of the face. The size and upturned bill argue against Pacific Loon. | The original documentation form event lasted from 09:15:00/09:45:00.
