The documentation form by Peter C. Petersen is the only one submitted and forms the basis of this record. Another observer was Brian Blevins. | Elimination of similar species: The only similar raptor would be an Osprey which is much larger, has a black mask, elbow with large black area, mottled gray underwing and on tail and dark on upper surface of wing. Gulls are closer, but wings with dark area at tips of wings on top side, shorter tail, different flight, not pursued by small birds. | The original documentation form event lasted from 09:30:00/09:35:00.

The documentation form by Dennis Carter is the only one submitted and forms the basis of this record. | Elimination of similar species: I considered the possibility that this might be an Ash-throated Flycatcher, a species that was recorded in Minnesota in Nov., 1990. The bird I saw lacked the pale coloration and slim appearance of Ash-throated. I feel that the bright yellow belly, contrasting with the dark gray chest eliminates Ash-throated. At no time during my observation, did I feel that this bird might be an Ash-throated Flycatcher. | The original documentation form event lasted from 10:30:00/11:00:00.

The documentation form by Ann Johnson forms the basis of this record. Another documentation form by Tim Schantz was submitted. Other observers include Roy Godwin and Jim Sinclair. | Elimination of similar species: Body and bill shape and behavior identified this bird as a flycatcher. The size, eye-ring and wing bars eliminated all but Empidonax flycatchers. Because of the late date on this bird, it is difficult to get an understanding of molt sequences which may or may not be helpful. From what I can find on molts, however, the following is based on best available information. | The original documentation form event lasted from 11:40:00/11:55:00 and approximately 13:30:00/14:00:00.

Bald Eagle was eliminated by lack of any white visible from below and the short head/long tail profile. | The original documentation form event lasted from 12:00:00/12:05:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Sinclair, Thomas H. Kent, and Jim Fuller were submitted later. | Elimination of similar species: Ring-billed and Herring gulls are the two most likely species of confusion. Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. | The original documentation form event lasted from 10:55:00/12:24:00.

The documentation form by Richard Jule Hollis is the earliest and the one that forms the basis of this record. Other documentation forms by Carl Bendorf were submitted later. Other observers include Janet Hollis and Cal Knight. | Elimination of similar species: red upper surface of Iower tail and lack of belly band eliminates Buteo lagopus white under side of tail (w/o terminal band) + white upper tail tend to eliminate B. jamaicensis. | The original documentation form event occurred at 16:00:00 for the sighting on February 4, 1979 and had no time for February 3, 1979.
