Although by no means a conclusive characteristic, the subject bird did not hover during the period we observed it, a characteristic typical of hunting Rough-legged hawks. Dark phase Swainson's hawk have much darker, barred flight feathers and tail when viewed from below than that of the subject bird. \| The original documentation form event lasted from 12:30:00/12:45:00.

Records Committee review for rare bird sighting of Ferruginous Hawk at Hichcock Nature Area, 1999	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1999-12-05	2000-11-28	Rare birds documentation form	Records Committee review of a Ferruginous Hawk at Hitchcock Nature Area in Pottawattamie County, IA on December 5, 1999. Includes a record review document with votes and a documentation form submitted to the committee.	Orsag, Mark	Ferruginous Hawk	Hitchcock Nature Area	Hitchcock Nature Area (Lodge Hawkwatch Point)	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.

Peregrine Falcon is smaller, has more pointed wings and has a much more distinctive head pattern. Goshawk's head pattern is different, is whiter below in gray plumage and has shorter wings.

Other documentation forms by Maridel Jackson, Ross Silcock, Jane R. Clark, and Jim Sinclair were submitted later. Other observers include John Cecil, Eugene Armstrong, and Eloise Armstrong. \| Elimination of similar species: Northern Goshawk- Although Goshawks have been known to show pointed wings, they are never as pointed as a Falcon's. I have seen many Northern Goshawks and jizz alone would rule this one out. I saw no barring on the tail. One of the prime field marks on a Goshawk are the bright white undertail coverts which this bird did not have. The bird in question also lacked a dark crown. Peregrine Falcon- Size. No dark helmet. Jizz (mentioned above). The bird lacked overall contrast of a Peregrine Falcon. Juveniles would be brown. Prairie Falcon- Color. Prairies are a brown bird in all plumages. The underwing was uniform with no black axillaries. Habitat. Prairies feed almost exclusively on small mammals. \| The original documentation form event occurred around 15:30:00.

Gyrfalcon	Lake Red Rock	Red Rock Reservoir, Marion Co. above the dam	flyover the ice	The documentation form by Matthew Kenne is the only one submitted and forms the basis of this record. \| Elimination of similar species: The lack of facial pattern and white throat and chest rule out peregrine, as the bird was flying almost directly into the sun (perpendicular to me). It wasn't as pale or brown as a prairie, and with shadow and distance there wasn't any dark/light pattern to the underwing. It wasn't black as a crow + the shape was wrong. Eagles were patterned and obviously larger. \| The original documentation form event occurred around 13:10:00.	Iowa Ornithologists' Union \| MS 166	9	4
