It had a 'blank look' around its eye. [...] This is definitely different from a Phil. Vireo with dark line through its eye and the Philadelphia's 'dark loral spot'. I've seen many Warbling Vireos (and have heard more) and I'm sure that it was a Warbling Vireo that I saw. | The original documentation form event lasted for 15 to 30 seconds.

The documentation form by Mark Proescholdt is the earliest and the one that forms the basis of this record. Other documentation forms by Beth Proescholdt were submitted later. | Elimination of similar species: Harrier - tail was not right and long enough for harrier and bird was not right color underneath. Nighthawk - Our bird was much bigger than Nighhawk and had no white patches in its wings. Turkey Vulture or Eagle - Our bird was much smaller and had long, narrow pointed wings. Accipiters - Body shape was wrong and did not have extra long tail -look like accipiters have. Osprey - Wrong body shape for osprey and no white markings on our bird. Buteos - Wrong body shape again even for Swainson's Hawk which can appear to have pointed wings when seen overhead. Buteos have much broader wings and should show some white contrasting colors underneath. Falcons - Our bird was too big for a Kestrel or Merlin. I don't think Merlins ever have leisurely, slow flapping flight. This bird didn't fly right for a Peregrine and the body proportions were not right for a Peregrine. I've seen Peregrines fly in a slow, leisurely manner and this did not seem to suggest a Peregrine at all. A Peregrine or Prairie Falcon should show some light-colored areas underneath. Also, a Peregrine's tail tapers down to a rounded end and is not squared off and flared at the end. | The original documentation form event lasted from 19:35:00/19:35:00.

It was an adult Kumlien's Iceland Gull because a Thayer's Gull has much more blackish coloration at the primary tips and more dark coloration at the primary tips than the Kumlien's which has grayish markings on the primary tips and less dark-colored markings at the primary tips overall. Also, a Kumlien's Iceland Gull shows the almost white wing tips like we saw with a little grayish markings on some primary tips. | The original documentation form event lasted from approximately 15:00:00/16:15:00.

Loess Hills / Missouri River Valley. The bird was coming from out of the valley. It crossed the wooded ridges of HNA and headed southeast.
|
The documentation form by Mark Orsag is the earliest and the one that forms the basis of this record. | Elimination of similar species: I considered 5 other species of raptor in total. I eliminated two possibilities (Rough-legged Hawk and Northern Harrier) within seconds of seeing the bird in question. I eliminated two others (Bald Eagle [imm.], and Red-tailed Hawk more or less during the minute or so that I had the bird in view. **** ** I reviewed, in my head, the fine points of the Krider's Red-tailed Hawk for a few seconds after the bird had disappeared from view. The fifth species came to mind just before I started writing this report (the next day). I retroactively eliminated it. In reconstructing my reasoning, I believe: Rough-leg was eliminated due to the unmarked white throat, breast, underwings, and underside. Northern Harrier was eliminated due [sic] the large size and robust shape of the bird, the flight pattern (especially wingbeat), the unstreaked white throat, etc. Immature Swainson's Hawk later eliminated by dark head, white wing patches on primaries, lack of dark flight feathers on underwing, unlikelihood of December sighting. Bald Eagle immature- (whitebelly I-II) was eliminated by the downpushing wingbeat, the colors of the bird's dorsal surface, the lack of a contrast on the dorsal surface between the brown-gray forward part of the wing and the darker flight feathers (a little known good fieldmark for Immature BE), and the confining of the white coloration to the primaries, etc. Red-tailed Hawk-This species, in light of its similar (but smaller) size and variable plumages, posed the greatest problems. The dark upper surface, dark head, pointed wings, and pattern of flight (dihedral in glide posture), as well as the distinct and identical nature of the white markings on the upperwings and the lack of patagial marks, "commas", or other dark markings on the underside, were considered in total and used to rule out the immature light-morph Red-tail and, on reflection, a partial albino Red-tail. Krider's Red-tailed Hawk was the toughest to rule out. Here are my reasons: 1. Krider's heads appear white/light in contrast to the darker (gray or brown) color of the back. This bird's head was not lighter in color (on top) than the back. Back coloring was too dark (brown-reddish) for Krider's-no white mottling seen. Wings were pointed not rounded. No 'headlight' fieldmark [sic] was seen and the 'points of light' fieldmark [sic] was. Dihedral in glide unusual but not impossible for a Red-tail, but the wingbeat (fluid and downpushing rather than centered on the downstroke at the wrist) did not look like a Red-tailed's. | The original documentation form event lasted from 09:00:00/09:01:00.
