Occurrence Remarks The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. Other observers include Beth Brown, Tim Schantz, and Jim Sinclair. | Elimination of similar species: A first winter Bonaparte's Gull, the most likely gull to be confused with this bird, was eliminated by the presence of a distinct black collar, black outer primaries, and white trailing edge of the wings. Other gulls which show a distinct "M" in flight include Little - eliminated by gray richer than brown mantle, lack of cap, pure white secondaries, and size; Ross's - eliminated by presence of collar, shape of tail, and extensiveness of tail band; Sabine's - eliminated by combination of gray mantle with full tail band and black carpal bar. | The original documentation form event lasted from 13:30:00/13:40:00 approximately.
