|
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.

The bird was not mottled in appearance as an immature Bald Eagle would be but was a rather uniform dark brown overall except for the white in the upper retrices and wing linings which was noted before. As we watched the bird through our binoculars and a 20x telescope another large bird appeared from the East and this too was another Eagle. The second bird was an overall dark brown except for a very small amount of white to whitish color at the base of the retrices. This bird had a lighter brown color to the back of the head and on the nape. There was no mottled effect as would be shown in an immature Bald Eagle. | The original documentation form event lasted from 10:00:00/10:30:00 approximately.

large, wide riverbottom marsh with scattered woods.
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: According to Eckert, the upper wing patches are diagnostic if the location is right. He gives the following example as an acceptable documentation: 'On the upper surface of each wing there was a rectangular or oval white patch on the flight feathers. This patch was on the inner primaries, and perhaps faded a bit into the secondaries and outer primaries.' This description fits the bird I saw. Eckert gives two other diagnostic marks that I did not see (feathered legs, rufous back and shoulders), but only one of these three marks is needed. The white tail is not diagnostic, but coupled with the light underparts and generally dark upper wing surface, tends to exclude Krider's and Harlan's Hawks which would have light upper wings and dark underparts, respectively. An ordinary Red-tailed Hawk would not ordinarily have an all white-tail nor such prominent upper wing patches. The raised wings in flight in the absence of wind favor Ferruginous Hawk over Red-tailed and Rough-legged Hawks. Rough-legged Hawk is excluded by the lack of prominent black and white pattern to body, wing and tail. | The original documentation form event lasted from 14:45:00/14:57:00.

The documentation form by Mike Dooley is the only one submitted and forms the basis of this record. Other observers include Bill Scheible, John Havilcek, Joyce Havilcek, and Jim Durbin. | Elimination of similar species: None eliminated on-site. Possible mis-identifications, given the premium conditions and extended period under which this bird was studied, might be as follows (consulting the National Geographic Society field guide): (1) fall adult Blackburnian Warbler: bird in question was strongly streaked on breast and sides, not just flanks; (2) female Townsend's Warbler: streaking on breast and sides of bird in question did not have semi-necklace effect of Townsend's; olive of head and back much grayer; (3) female Praire [sic] Warbler: bird in question had extended yellow post-occular stripe; streaked breast, not just sides and streaks bolder; had white belly; (4) fall Blackpoll Warbler: bird in question was much more boldly streaked on breast and sides; had extended post-occular yellow stripe, clearly defined cheek patch. All of above eliminated due to bird in question having wings similar to back color and not of a contrasting charcoal, as well as having a bold yellow-olive rump. All but Praire [sic] Warbler eliminated due to bird in question's virtual lack of wing bars. | The original documentation form event lasted from 13:45:00/15:00:00.
