The documentation form by Bill Ohde is the only one submitted and forms the basis of this record. Other observers include Ron Cross. | Elimination of similar species: Our first thought was swan when we saw the the [sic] large white bird in the water. We first used binoculars and immediately saw the huge orange bill. Then I got out the spotting scope to take a close look. | The original documentation form event lasted from 11:30:00/15:00:00.

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: Separation from Semipalmated Sandpiper rests on the bill. The behavior is a bit supportive. Based on records for Iowa, we do not yet know which species is more likely. Having to travel to South America, it would seem that semipalmateds would pass through Iowa earlier, but pectorals go just as far south and some are late migrants. | The original documentation form event lasted from 14:00:00/14:20:00.

Thornburg is the only one submitted and forms the basis of this record. | Elimination of similar species: The American Kestrel is of a similar shape, but is smaller and usually has some reddish plumage on the back or tail. The Sharp-shinned Hawk is similar in size and color especially the immature. The long-pointed wings of the Merlin differ from the wings of the Sharp-shinned Hawk.

Large round backwater lake kept open by output from Quaker Oats Plant. The lake was half frozen two days ago, but two warm days made it ice free.
|
The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. | Elimination of similar species: The short legs and large rounded head with thick neck are the main features that distinguish immature Black-crowned from Yellow-crowned Night-Herons. The round white dots on the upper wing are supposed to be more prominent on the Black-crowned, but this is difficult for me to judge. | The original documentation form event lasted from 13:05:00/13:30:00.

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.

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.
