The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Although the duskiness on the face had somewhat of a "hooded" effect, any of the hooded gulls could be eliminated by the bill structure. The pale primaries eliminated all but the white-winged gulls - Glaucous, Iceland, and possibly Thayer's. Glaucous can be eliminated by size and bill color. Thayer's was eliminated because of: 1) overall gray-white appearance; 2) the lack of any secondary bar; and 3) the checkered tertials. Problems with the record are the duskiness on the face and the narrow dark edging to the outer primaries from below. These two characteristics may well indicate an Iceland/Thayer's intergrade. | The original documentation form event lasted from 13:15:00/13:40:00.

Iceland Gull was eliminated based on the darker secondaries and wide, brown tail band. | The original documentation form event lasted from 16:50:00/17:15:00.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Iceland Gull - basically eliminated by darker color and narrow chocolate edges to outer primaries. Kumlien's - presence of tail band would seem to eliminate Herring - eliminated by combination of: structure and size of body and bill; shape of head; more uniform coloration above, especially lighter colored primaries; light flight feathers from below contrasting with darker wing lining; lighter color of tail band | The original documentation form event lasted from 10:30:00/10:35:00.

The head was also a bit flatter and it rode higher in the water, just giving a different posture than a loon. Plumage details did not fit any loon. Western Grebe- Thicker neck, some color on neck and white cheek eliminated this one Pied-billed Grebe - Size, bill shape, and other features wrong. Horned/Eared Grebes - Although it gave much the same appearance as a horned grebe, size and bill eliminated both. | The original documentation form event lasted from 16:34:00/16:42:00.

Cormorants were eliminated because of straight posture, lack of throat patch, and basic plumage configurations. The bird was obviously larger than a Pied-billed Grebe which would, in addition to the yellow bill, eliminate all but Western Grebe. Western Grebe would have looked much larger than the various waterfowl nearby and would not have shown any rust color on the neck. | The original documentation form event lasted from 12:45:00/13:05:00.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Size, shape and flight pattern initially eliminated buteos and accipiters. I seriously considered both Northern Harrier and Peregrine Falcon. Until the bird got close enough to see the underparts, Peregrine was the most likely candidate based on the straight trailing edge of the wing, although I have never seen a Peregrine glide so effortlessly with few wing strokes taken. The flight pattern and white head made me aware that this was probably a kite. Of the other possibilities for this bird, all were eliminated by the white tail with no markings. Only a Ferruginous Hawk would share this characteristic. The black carpal spots on white wing linings were somewhat reminiscent of an Osprey, but other patterns, size, and flight pattern are not consistent. Although Northern Harrier males look very white from below, their heads are dark not white, and only the outer primary tips are dark as opposed to this bird's entire primary area. The tundra race of the Peregrine Falcon would appear light colored on the head, but would also show more dark markings underneath than this bird had. Mississippi Kite looks fairly white headed at a distance, but the underparts and tail are gray. | The original documentation form event lasted from 18:05:00/18:07:00.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: The body and bill structure eliminated all but hooded gulls and the brown plumage indicated a first year bird. Size close to Ring-billed, in addition to plumage already described, eliminated some of the smaller hooded gulls. The most likely candidate for confusion would be the Franklin's Gull. Juvenile Franklin's shows a hooded pattern early in development rather than a brown wash on the head. Franklin's tail band would also be incomplete with white feathers showing on the outer edge. It would also show fewer dark primaries, with the inner flight feathers more approximating the mantle and inner wing color. No other small gull has this characteristic. | The original documentation form event lasted from 11:45:00/12:10:00 and 15:30:00/14:00:00 [sic].

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: This was a classic case of delayed reaction as I began sorting through in my mind as I drove down the road. The large size and bulk of the bird, plus the broad, rounded tail made it an obvious buteo. After double-checking all phases of the rough-legged hawk in Clark's Hawks, I once again eliminated rough-leg because of the nearly all white underparts. However, redtail wasn't fitting either, even a light phase, and a few miles down the road the ferruginous crossed my mind. I pulled off the road, made a few notes, and began researching with the guides at hand. The most troublesome field mark was the 'white tail with gray band.' I have seen numerous redtails give the white rump appearance but none have had the distinctive white tail/gray terminal band. There was absolutely no dark patagial marking on the underwing. The combination of field marks (or lack thereof) would seem to approach an immature Krider's redtail. I eliminated this bird because of the appearance of one, wide gray tail band and the more uniform coloring of the body - very little white mottling. Although I wish I'd had a longer look, I came to the conclusion that the combination of what I had observed pointed toward an immature ferruginous hawk. | The original documentation form event lasted from approximately 09:00:00/09:01:00.
