The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: On the basis of the dark hood, size, and dark gray mantle, all gulls except for Laughing and Franklin's gulls can be removed from consideration. I will admit that I was skeptical that a Laughing Gull could show up in Iowa on such an early spring date; most interior records are from May-June. But, given the evidence, I am convinced that this bird was indeed a Laughing Gull. The size of this bird, nearly that of a ring-billed gull, favors Laughing Gull. The bill shape and size, length of the legs, wing pattern, and extent of the eye crescents also favor Laughing Gull. An adult Franklin's Gull can be eliminated by the lack of a white bar separating the gray inner wing from the black wingtip. One year-old Franklin's Gulls, however, may show a wing pattern like that of this bird. But, according to Kaufman (1990), such a Franklin's Gull should show some white flecks on the hood, and would be most likely encountered in late spring and summer. | The original documentation form event lasted from 10:48:00/11:34:00 and 12:26:00/13:20:00.

|
The documentation form by Brian Blevins is the only one submitted and forms the basis of this record. Another observer was Corey Blevins. | Elimination of similar species: About the only thing that is close is the Bufflehead and they were feeding with this bird, thus contrasting them was easy. The head difference was unmistakable with the buffs having an all dark head with a white spot, where as the smew had a white head with a black patch. | The original documentation form event lasted from 15:13:00/15:36:00.

|
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 pointed wings indicate a kite or falcon. The gliding flight was that of a kite not a falcon. The white body and head also eliminates all falcons. The lack of white rump as well as the flight pattern eliminate Northern Harrier. Swallow-tailed Kite would have a forked tail and different flight pattern. Black-shouldered Kite has a white and black shoulder. The lack of white patches in the secondaries and brownish tail indicate a subadult (first year bird). I looked for bands in the tail, but could not appreciate them. Failure to see bands could be due to the lighting and distance or, as noted by Clark and Wheeler, to the fact that "A few immatures have solid, unbanded dark brown tails." The prominent light and dark underwing puzzled me, but Dunne says that "Immature has body and underwing coverts buffy, with dark streaking and spotting of variable density; may be lighter or darker than illustrated." The underwing coverts and body appeared about the same shade to me. The lighting and distance may have precluded my appreciating any streaking. This bird appeared lighter than the bird I saw at Dudgeon Lake last year, especially the underwing coverts. The profile and flight characteristics allowed me to immediately recognize the bird as a Mississippi Kite. | The original documentation form event lasted from 13:35:00/13:36:00.

[...] He put me in mind very much of a catbird in size and contours. | The original documentation form event lasted around "evenings and 1 morning" from around May 22 to the first week of June 1990.

|
The documentation form by Dawn L. De Vore is the only one submitted and forms the basis of this record. Other observers include Don Poggensee and Pam Poggensee. | Elimination of similar species: Loggerhead Shrike: On the bird that was seen the top of the bill was dark black and the bottom was a lighter in color. A Loggerhead has a completely black bill. The bird that was seen was a light gray, much lighter than a Loggerhead adult. The bird was not a juv. Loggerhead because the black patch on the head is very different than that of a Loggerhead. On a Loggerhead the black area or patch is very wide and runs along both over and under the eye, it also continues back toward the back of the head meeting up with the gray on the back of the birds head. On the bird that was seen the black area or patch did not run both over and under the eye, it only ran under the eye. Also the patch did not meet up with the gray on the back of the birds head, the black area was surrounded on three sides by white, never letting the black meet up with the gray. | The original documentation form event lasted from approximately 15:00:00/15:10:00.

Long-tailed Jaeger is eliminated by the presence of a white crescent on the upper surface of the wing.

Dinsmore, Stephen J.
|
California Gull
|
Oak Grove Recreation Area
|
[...] Oak Grove Beach Recreation Area at Saylorville Reservoir, Polk County.
|
|
The article by Stephen J. Dinsmore forms the basis of this record. | Elimination of similar species: [...]The bird was similar in size to the largest Ring-billed Gulls, but slightly larger than others. I approached closer and noted that, when compared to a Ring-billed Gull, the bird had duller yellow legs, a stouter bill with black and red spots near the tip of the lower mandible, and a darker gray mantle. [...] The bird was slightly larger than most of the Ring-billed Gulls, although one or two of the biggest Ring-billed Gulls were as large as the bird I was studying. Proportionately, the bird was heavier and larger-headed than a Ring-billed Gull. [...] I estimated the mantle color to be about midway between those of Ring-billed Gull and a Lesser Black-backed Gull. [...] The bill was heavier than the bill of a Ring-billed Gull and had a distinct gonys. The legs were pale gray-green, unlike the bright yellow legs of a Ring-billed Gull. Leg length appeared similar to a Ring-billed Gull. | The original documentation form event lasted from 07:45:00/09:27:00.

The documentation form by Tanya Bray forms the basis of this record. Another documentation form by Ross Silcock was submitted. Other observers include Babs and Loren Padelford. | Elimination of similar species: This bird differed from Franklin's Gull in the following ways: 1. Less extensive black on head. Eye coverts were not immediately noticable [sic] due to white cheek area. 2. Longer legs, more upright posture, and generally a very long, slender bird. 3. In flight, the bird had long slender wings with completely dark primaries; no white dividing the tips of the outer primaries from the rest of wing, and no white tips to outer primaries. Underside of primaries as described above. 4. Bill was long, curved and slightly swollen and hooked at tip. | The original documentation form event lasted from around 07:35:00/07:36:00, 08:45:00, 12:15:00, and 18:30:00.

The documentation form by Ken Lowder is the only one submitted and forms the basis of this record. | Elimination of similar species: Sora; eliminated by size and color. Yellow rail: absolute lack of white wing patches; My bird was black - with no suggestion of lighter color anywhere. Virginia rail: eliminated by size and color of bird Could possibly have been a rail chick of another species - ruled out because of presence of chicks at this late date + would have been extremely extraordinary; and because chicks would be incapable of flight. | The original documentation form event occurred around 11:00:00.

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: 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.
