River bottom and large field with scattered trees. The bird glided over from south to north and disappeared.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other observers include Dick Tetrault. | Elimination of similar species: We were looking for a Swallow-tailed Kite reported the day before, but this bird did not have the forked tail and contrasting black and white of that species. The underparts and tail were not white as would be expected for Black-shouldered Kite. I did note any contrast in the upper wing (white posterior edge of inner wing) -- I may not have seen this or this could of been a first-year bird that lacks this mark. The failure to flap wings and overall gray color is inconsistent with any falcon. I saw a Swainson's Hawk earlier in the morning and its contrasting underwing was very different than this bird. A Red-tailed Hawk was also seen earlier and had an obvious buteo shape. | The original documentation form event lasted from 10:27:00/10:29:00.

Rather open urban area on southwest side of Des Moines in bottom land. There is a large deck behind the house with hummingbird feeder hanging from the eve and crab apple tree behind the deck and adjacent to the garage. A large vacant field is behind the property.
|
The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other observers include Don Stolz, Carole Stolz, Eugene Armstrong, Eloise Armstrong, Pam Allen, Reid Allen, Ann Johnson, Jim Dinsmore, Jim Fuller, Bob Cecil, and Aaron Brees. | Elimination of similar species: My experience and references of Buff-bellied Hummingbird suggest that the cinnamon color, extent of this color toward the throat, cinnamon rump/back, and white eye spot do not fit this species. I believe that the features shown in the photo of the Arizona 'mystery' bird in Field Notes are a perfect fit for the Des Moines bird. I do not know of specific information on bird trafficking in Iowa. We had a Yellow Grosbeak north of Des Moines in December 1990, the origin of which was never explained. | The original documentation form event lasted from 07:50:00/08:40:00.

|
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.

Bird was in old willows at edge of reservoir.
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: The brown color most closely matched that shown by Peterson (1980) for the male Black-headed Grosbeak. The features I saw best were the brown rump, the contrast between the brown breast and flanks and gray belly, the thin white wing bars, and the darker color of wings and tail. The fact that the bird was singing loudly and continuously indicates that it was a male. The lack of breast streaking, dark color, and failure to see an eye stripe also argue against the bird being a female. The rich brown coloration only fits Black-headed Grosbeak. No features that fit Rose-breasted Grosbeak, such as red on the breast or underwings, white flanks or rump, or light-colored bill, were seen. Failure to see a demarcated black head and white in the wing and tail in flight is disturbing, but the side to back lighting and brief duration of each look at the bird (when I concentrated on looking at the features cited above) may account for this. The wing bars were not as wide as usually depicked [sic] for males. Perhaps the bird was in first nuptial plumage. | The original documentation form event lasted from 08:20:00/08:30:00.

The documentation form by Thomas H.

Pacific Loon would have a straight bill and darker top of head and back of neck. I did not see any chin strap, but this would have been difficult to see. The fact that I saw the eye in the white area appears to exclude Pacific Loon. The upper parts were lighter than in the two Pacific Loons that I saw this fall. The relatively white fore-neck and face suggests an adult. | The original documentation form event lasted from 10:05:00/10:30:00.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Carl Bendorf, Mike Newlon, and many unidentified other observers. | Elimination of similar species: Photographs taken at the first encounter with a Celestron 750 mm lens demonstrate the size difference, the bill and head shape difference, the lighter overall color, and the window in the wing. An adult Herring was in the photo with the Thayer's on 7 Nov and imm Herring were photographed on 10 Nov for comparison. | The original documentation form event lasted from 09:25:00/09:50:00 and 11:00:00/11:20:00 on November 7, 1981 and 07:30:00/08:30:00 on November 8, 1981.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Chuck Fuller, Jane Fuller, and Jim Fuller. | Elimination of similar species: I studied the Common Loons seen earlier in the morning. They presented a wide spectrum of face patterns and size. I based the identification of Pacific Loon subjective evaluation of size, bill shape and size, sharp line of separation of black and white on the neck, and chin strap. | The original documentation form event lasted from 09:00:00/09:10:00.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Dick Tetrault. | Elimination of similar species: The size and shape in comparison with Baird's Sandpiper establish this bird as a peep. The black legs, gray color, and lack of bib exclude Least Sandpiper (several of which were seen earlier). The distinction from Semipalmated Sandpiper is based on the bill and apparent molt to basic plumage. Five minutes earlier I had seen two Semipalmated Sandpipers running on the other side of the area; they had short straight bills and had all feathers of the upper parts edged with buff (juvenile plumage). I had seen a number of Semipalmated Sandpipers with longer and slightly drooped bills this fall, but none approached the length, thinness, and droop seen on the current bird. According to Kenn Kaufman's Advanced Birding, Semipalmated Sandpipers wear their juvenile plumage until they reach wintering grounds, and juvenile Western Sandpipers gradually molt from juvenile to basic plumage from August to October with some retaining rusty scapulars. I assume, based on date, that this bird was probably a first-year bird, and that it had either completely molted to basic plumage or had some rusty scapulars that I did not see. I did not consider any of the Eurasian stints, which would be exceeding unlikely and have bills more like a semipalmated or have yellow legs. | The original documentation form event lasted from 10:15:00/10:20:00.
