Kent, Thomas H. (Thomas Hugh), 1934-
|
Ferruginous Hawk
|
Otter Creek Marsh State Wildlife Refuge
|
Otter Creek M., Tama Co., Iowa
|
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 James P. Mattsson is the only one submitted and forms the basis of this record. Other observers include Michael Bornstein. | Elimination of similar species: [...] The bird was most similar to the dark phase rough-legged hawk (Bureo lagopus) in size and general shape, but the latter species lacks the deep rust coloration on the upper wing coverts, scapulars, and upper back, and also has some dark banding on the outer one-half of the tail. 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.

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.

A red-tail might have one or the other white, but not both tail and head in my experience. Also the red-tail usually has a darker shade of brown on its middle belly, if it has color there. The rough-legged has a dark tail band which at that proximity should have been seen and its color is also a darker brown. | The original documentation form event lasted from 08:25:00/08:26:00.

Other documentation forms by Jim Fuller, Babs Padelford, Loren Padelford, and Ross Silcock were submitted later. Other observers include Dick Tetrault, B.J. Rose, and Doug Rose. | Elimination of similar species: An immature White-faced Ibis could lack the red eye, red legs, and white facial feathering of an adult and be confused with a Glossy Ibis. An immature white-faced would lack the blue facial skin and would likely show some brownish feathers. The color differences were clear-cut and observed under identical viewing condition. | The original documentation form event lasted from 13:30:00/13:40:00, 14:20:00/15:25:00, and, on May 19 from 08:40:00/08:45:00.
