The documentation form by David J. Conrads is the earliest and the one that forms the basis of this record. Other observers include Keith Franzen and Nixon Wilson. | Elimination of similar species: Due to its significantly smaller size than a Cooper's Hawk, we concluded that it was a HY male Sharp-shinned Hawk. We also listened to "A Field Guide to Bird Songs" and although the Sharp-shinned recording was that of 175 "kek-kek-kek" warning/alarm call, the Cooper's Hawk recording was that of a food begging call which was very similar but of a significantly lower pitch than that of the bird we observed. | The original documentation form event lasted from 14:30:00/14:31:00.

|
The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Mary Noble and Dick Tetrault. | Elimination of similar species: The overall coloration and plainness indicate a female or immature bird. The lack of prominent gray in the auriculars and light bill color argue against Hepatic Tanager. The bill length, head shape, and relative paleness of the wings favor Summer Tanager over Scarlet Tanager. The lack of prominent wing bars appears to exclude Western Tanager. The apparent lack of orange tint suggest a bird from the West or perhaps an immature. The Summer Tanager photographed at Pleasant Valley in Scott County on 2 December 1990 was more orange-yellow than the Iowa City bird. The latest Midwest record for Scarlet Tanager in books of these states was 26 Nov in Minnesota. There are a few winter records of Summer Tanager: in Tennessee (4) 5, 18, 21 Dec and 2 Feb-15 Mar; in Michigan 1 Dec; in Missouri 3-10 Jan 1987. There are also winter records from Florida and the Texas Coast. This does not constitute an exhaustive search for winter records. | The original documentation form event lasted from 08:10:00/08:15:00.

The documentation form by Brian Blevins is the only one submitted and forms the basis of this record. Another observer was Lewis Blevins. | Elimination of similar species: Summer, Scarlet, Western Tanager. Scarlet Tanager was eliminated by the lack of dark wing and the orange-green instead of yellow-green. Western Tanager was eliminated by the lack of wing bars. Summer Tanager: this was the closest of the three especially considering the cooperi form found in the southwest. The large bill in common to both species if we consider the cooper form of the summer, however, the color of the mandible overall more dark than light lends the pull towards hepatic. The dark, brown orange-green also pulled me over to the hepatics in respect to the ones I have observed in Arizona. Call note also differs. | The original documentation form event lasted from 13:15:00/14:20:00.

The documentation form by Ann Johnson and Jim Bangma is the earliest and the one that forms the basis of this record. | Elimination of similar species: The powerful direct flight, the longish tail, and the rounded broad wings identified this bird as an accipter. Bangma's first comment was that the width of the wings reminded him of Hook-billed Kites in So. Texas, a dramatic characteristic that allows experienced hawk watchers to identify Northern Goshawk from a distance - literally a stovepipe with broad wings. Buteos have a much shorter tail that gives them an entirely different look and feel. A gray adult male Northern Harrier would look white below and have longer wings proportionate to the body. Although we were unable to see the bird at an angle to see every characteristic of this species, other accipters would have been rufous or brown from below. Although this is certainly a late date for this species, Northern Goshawk has been seen in the winter in and near this location. In breeding areas it feeds on grouse. We speculated on the reintroduction of Ruffed Grouse in this area and what effect it might have on late migration and even potential breeding. | The original documentation form event lasted from 13:45:00/13:46:00.
