The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by James J. Dinsmore was submitted later. | Elimination of similar species: The dark coloration, gull-like shape, and white color in the primary shafts identified both birds as jaegers. Initially, I thought the bird I saw on the 10th was a Parasitic, mainly because of the size and seemingly bright, rust-colored underparts. However, better viewing conditions later showed that the underparts were instead a pale brown color and lacked any hint of rusty color. Long-tailed Jaeger was easily eliminated by size, shape of the central rectrices, and the greater amount of white in the wing. Parasitic Jaeger was more difficult to rule out. The combination of size, wing shape, amount of white in the wing, shape of the central rectrices, and bill size was used to rule out juvenile Parasitic Jaeger. | The original documentation form event lasted from 09:35:00/12:33:00 on November 10, 1996 and 10:55:00/16:05:00 on November 11, 1996.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent and Jim Fuller were submitted later. Another observer includes Chuck Fuller. | Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). | The original documentation form event lasted from 11:30:00/13:10:00.

Other observers include Doug Rose, Roger Rose, and Ken Lowder. | Elimination of similar species: Because of the fairly small size and conspicuous dark spot behind each eye, the bird must have been a Bonaparte's, Little, Common Black-headed, or Ross' gull, or a kittiwake. Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing. Both kittiwakes eliminated by bill color, lighter mantle color, and differences in wing pattern. | The original documentation form event lasted from 16:17:00/16:42:00.

Second winter Lesser Black-backed Gull eliminated by smaller size, browner uppertail, and heavily streaked head and underparts. | The original documentation form event lasted from approximately 16:00:00/16:15:00 on November 30, 1986 and 15:55:00/16:08:00 on December 1, 1986.

Records Committee review for a Red-throated Loon at Red Rock Reservoir, Marion County, IA on November 7, 1992. Includes a record review document with votes, an Iowa Bird Life article, and five documentation forms submitted to the committee.

Red Rock Reservoir - Roberts Creek area - (Marion Co.)

The documentation form by Mark Proescholdt is the earliest and the one that forms the basis of this record. Other documentation forms by Diane Porter, Thomas H. Kent, Ray Cummins, and Jim Fuller. Other observers include Ann Barker, Ann Johnson, Matt Keene, Jim Sinclair, Tim Schantz, Harold White, Hank Zalatel, Beth Proescholdt, Loren Padelford, Diane Porter, David Youngblut, Tom Klein, Francis Moore, and Ray Cummins. | Elimination of similar species: The bill size and small size of the loon helps eliminate a Common Loon. A Pacific Loon would have a sharp contrast on the side of the neck between light and dark colors. | The original documentation form event lasted from 11:30:00/11:45:00 and 16:30:00/16:32:00.

The documentation form by Robert K. Myers is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: The gull was too big and had too large of a bill for herring gull. The checkered back + very contrasty head + upper breast with lower are not consistent with herring. Basically size of bird + its bill eliminated most everything. | The original documentation form event lasted from 18:30:00/18:45:00.

The documentation form by R. Craig Hensley is the only one submitted and forms the basis of this record. | Elimination of similar species: The surf scoter and black scoter are similar. However, the specimans [sic] that I observed had the white wing patch that these two species do not have. In addition, two of the birds seen had white about their eyes, as neither of the other two have. | The original documentation form event lasted from 08:20:00/08:45:00.

Kent, Thomas H. (Thomas Hugh), 1934-

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.
