Records Committee review for rare bird sighting of Ferruginous Hawk at Benton Township in Fremont County, 1989	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1989-01-17	1993-08-05	Rare birds documentation form	Records Committee review of a Ferruginous Hawk at Benton Township in Fremont County, IA on January 17, 1989. Includes a record review document with votes, field notes of the sighting, and a documentation form submitted to the committee.	Silcock, W. Ross	Ferruginous Hawk	Benton Township	Benton TWP, Fremont Co., IA.	Open Missouri riverbottom; soybean stubble fields	The documentation form by Ross Silcock is the only one submitted and forms the basis of this record. \| Elimination of similar species: See attached discussion. (After writing my field notes at the site of observation and returning home later I found the stnadard field guides most unhelpful. Dunne et al's discussion of Ferruginous was tremendous, indicating variation in Ferruginous Hawks, and especially in discussion of flight characteristics, 'jizz', and behavior [...] The only possibility which is realistic to consider is Redtailed [sic] Hawk, or possibly Rough-legged Hawk. While similar in 'jizz' to a rough-leg (long tail, flight with 'crooked' (=osprey-like) wings, darker mottling underneath, longish wings), Roughleg can be eliminated by the following characters - absence of characteristic underwing pattern, including significant wrist mark (Ferruginous should show this to some extent according to Dunne et al, but I did not see it; remember I did not see the underparts well), and method of hunting-I have never seen a roughleg fly this low over the ground for this long (about a mile) - much lower and more consistently so than a harrier. Regarding elimination of Red-tail - I really think it is easier to eliminate Red-tail than rough-leg based on 'jizz'. The tail was too long, was never spread, and wings were long than Red-tail's. Tail pattern and 'three points of light' combination also is never seen on a Redtail [sic], especially when viewed from above. (The similarity to Roughleg [sic] in pattern can be seen in the front end paper in Dunne et al). Habitat and behavior also are important - while Redtails [sic] are very common in Fremont County, they are definitely not common on the open Missouri bottomlands. Redtail [sic] is a bird of edge habitat. I always look closely at any buteo seen from October to April on the open bottomlands. I have never seen any other buteo fly as low to the ground for as long as this bird - when i say low, I mean 1-2 ft above the ground. At no time was the bird higher than 6', and that was when perched on possibly the lowest post for some distance. Even a Harrier will rise and fall while hunting. This bird stayed low, in the manner of a hunting Golden Eagle (which I have seen in Western Kansas) - a point also mentioned by Dunne et al. Another point noted by Dunne et al and also shown in my sketch (purposely!) and, mentioned in my field notes was the osprey-like crook in the wings-while flying low over the ground. Dunne et al note that this is characteristic of a hunting Ferruginous. \| The original documentation form event lasted from 15:30:00/15:45:00.	Iowa Ornithologists' Union \| MS 166	9	1

Johnson, Ann	Ferruginous Hawk	Lake Red Rock	Lake Red Rock, Marion Co, IA	pasture with wooded draw to the south	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.
