The documentation form by Ann Johnson forms the basis of this record. Another documentation form by Tim Schantz was submitted. Other observers include Roy Godwin and Jim Sinclair. | Elimination of similar species: Body and bill shape and behavior identified this bird as a flycatcher. The size, eye-ring and wing bars eliminated all but Empidonax flycatchers. Because of the late date on this bird, it is difficult to get an understanding of molt sequences which may or may not be helpful. From what I can find on molts, however, the following is based on best available information. | The original documentation form event lasted from 11:40:00/11:55:00 and approximately 13:30:00/14:00:00.

Least Tern

Cone Marsh Wildlife Management Area
|
Cone Marsh
|
State owned marsh of about 700 Acres.
|
The documentation form by Carl J. Bendorf forms the basis of this record. Another documentation form by Thomas J. Staudt was submitted. | Elimination of similar species: The obvious possibilities are both Common or Forsters' Terns. At the very most, this bird was perhaps half the size of the gulls. This would put the body length in the general range of 8" long with a wingspread of 24" (according to size of Ring bills in the Natl. Geo. Guide) The Natl. Geo. Guide gives the general size range of Least Tern as 9" long with a wingspread of 20 ". The sizes of the other terns are given as Common L 14 1/2', W 30", and Forsters' L 14 1/2, W=31". Thus on size alone, Least Tern seems to be the only reasonable choice. The short but deeply forked tail also indicates Least Tern. Harrison's SEABIRDS says, on page 182, "Size and hurried flight,..., usually sufficient to clinch identification in northern hemisphere". The flight of this bird was much quicker and fluttery compared to my experience with the slower, deeper, and more deliberate flight of Common and Forster's Terns. | The original documentation form event lasted from 09:30:00/09:32:00.

The documentation form by Rick Wright is the only one submitted and forms the basis of this record. Other observers include Ken Strom and Marie Strom. | Elimination of similar species: [...] The different mantle colorations of the herring and ring-billed gulls were distinguishable. [...] The presence of other gull species convinced me that I had accurately judged the mantle color of this bird; I was able to compare it with 3 other species, as well as Caspian terns. The size and bill size rule out great Black-backed, the only dark-backed gull with which I am familiar. Although western gull would show a similar upper-wing pattern, I suspect that it too would appear heavy-billed (and would not have yellow feet). Yellow-footed gull is also large and deep-billed, and is probably less likely than lesser black-backed in Iowa. | The original documentation form event occurred around 13:30:00/13:30:30.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The most similar-appearing species is first-basic Herring Gull. The combination of slightly smaller size, longer wings, whiter rump, more speckled mantle, contrast between the darker mantle and lighter head, and darker upperwings lacking a pale "window" eliminated Herring Gull in first-basic plumage. | The original documentation form event lasted from 15:22:00/15:40:00.

The documentation form by Ann Johnson forms the basis of this record. Other documentation forms by Jim Sinclair, Raymond Cummins, and James Fuller were submitted. Other observers include Marlys Huff, David Youngblut, Pete Wickham, John Daniel, and Ken Lowder. | Elimination of similar species: Great Black-backed Gull- The bird was not large enough nor was the bill as massive. The great black-backed should also show a whiter head and lighter inner primaries and the back would be more of a checkerboard than the scaliness of this bird. Herring Gull- Because of variability, eliminating the herring was more problematic. Size was not particularly helpful initially in that this bird was near the second-year herring gull for such a brief time that I really couldn't make comparison. The variable sizes of ring-bills were of no help because next to some it looked huge and next to others it was only some larger. Some subtle differences were helpful in making this bird "look different" but I don't believe they could be considered sufficient. The checkered, scaly look was more pronounced than most juvenile herrings. The wings seemed long as they extended beyond the tail. The bill was entirely black and the tail band more distinct than most juvenile herrings. The color distinction between the head/tail and body from a distance were also helpful. The clincher, however, was during flight when no "windows" were visible on the inner primaries and the dark secondary coverts created a wide, dark trailing edge to the wing. These flight indicators, as well as size differential, were confirmed on the 23 October sighting. | The original documentation form event lasted from 15:10:00/16:00:00 and 16:15:00/16:40:00.

The documentation form by Eugene Armstrong is the only one submitted and forms the basis of this record. Other observers include Eloise Armstrong, Cal Knight, Bernie Knight, Maridel Jackson, and Barb Bettis. | Elimination of similar species: Ringbills never have a scaly pattern over the back or an all black bill. Smaller than a herring gull. Herrings only have a black bill when they are in brown juvenile plumage. 1st summer herring has a 2/3rds pink bill. | The original documentation form event lasted from 11:15:00/11:35:00.
