The field guides are agreed that the crown of the Brown-headed is brown, but there is a lack of unanimity in their descriptions of the crown of the Pigmy. [...] Margaret Brooke, in writing up the observation for IBL, describes the cap as being "brownish" but has no doubt about this nuthatch being a Pigmy. Mary and I feel the grayish olive description comes closest and cinches the Pigmy identification. | The original documentation form event occurred around 09:30:00.

|
|
The documentation letter by Manit Bunnimit is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] It flew for most of the time by soaring with its wings held very flat, only twice flapping its wings momentarily (shallow wingbeats) and once folding its wings rather tightly and gliding. All of the crows I have seen flap steadily, gliding only occasionally. [...] It could not have been mistaken even for the tails of the occasional American Crows that appear quite rounded. The sheer size of the bird and the wedge-shaped tail were enough to distinguish it from any of the crows, but what about the Chihuahuan Raven? Fortunately, as it flew by, the bird made two brief call notes that were very hoarse (sounding much more like grrrawgk than the gaw of the American Crow), and much deeper than the Chihuahuan Raven that I heard in northern Texas. However, because it has been a few years since I had seen or heard the Chihuahuan, I decided to double check the calls on a tape I had at home. The tape and I agree that the call was that of a Common Raven. | The original documentation form event lasted from approximately 11:10:00/11:11:00.

[...] At this point, I thought it could be a Scarlet Tanager. [...] As I watched it, the bird was taking off from the grass, flying into the air to snatch an insect, then landing on a nearby fence.

The documentation form by Ross Silcock is the earliest and the one that forms the basis of this record. Other documentations by Babs and Loren Padelford as well as Paul Lehman were submitted later. | Elimination of similar species: [...] Later it was seen at rest with Ring-billed and Franklin's Gulls, the latter group including a few individuals of the same age as the Laughing Gull, allowing careful comparison. [...] The wings were long and pointed, the overall jizz of the bird more attenuated than a Franklin's. [...] There was a grayish-black wash over the crown and nape, slightly intensified in the upper nuchal area, and a paler grayish wash on the flanks in the area below the bend of the wing, imparting a "dirtier" look to the underparts than on same-age Franklin's Gulls (seen when at rest). At rest, the black primaries extended well past the tail, a feature compared easily with nearby Franklin's, and there were no small white crescents in the primaries of the Laughing Gull, a feature easily seen in same-age Franklin's nearby. The Laughing Gull was almost as big as the Ringbills near it, while it appeared significantly larger than the adjacent Franklin's. | The original documentation form event lasted from 11:30:00/11:40:00.

Upon returning home, however, we found in Bent, "The note of the Smooth-billed ani has been called a wailing or whining whistle - resembling the notes of the wood duck." Our bird's call note was not a whistle at all. And then we found in Pough's Eastern Land Birds under Smooth-billed ani, "The two anis are hard to tell apart except by note, the whining notes of this species being in sharp contrast to the soft double note of the Groove-billed." So for my part, that settled it that our bird was a Groove-billed ani. | The original documentation form event occurred in the afternoon

The documentation by William and Rebecca Otto is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] We eliminated the possibility of the gull being an immature Bonaparte's gull by the following criterion: 1. Leg color. The gulls legs and feet were entirely black. Bonaparte's gull have reddish legs. This was apparent at great distance on the immature Bonaparte's gulls present. 2. Primary feathers. The gull had black outer primaries and gray inner primaries. Immature Bonaparte's having some obvious white inner primaries.) 3. Behavior. Although this may seem rather unscientific, the gull not joining the groups of feeding or loafing gulls present seems significant to me. | The original documentation form event lasted around 30 minutes.

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.

If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

The documentation form by W. Ross Silcock is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] Smaller than adult Herring Gull (winter plumage, red spot end of lower mandible) beside it, legs a little pinker. Larger than Ring-billed Gulls- flock of 14 adjacent. [...] Headmuch [sic] smaller relative to body than in the Herring Gull- also flatter-appearing. [...] 1. Bill was black (or very dark); this , combined with the rather pale underparts relative to the rest of the (also rather pale) plumage tends to rule out a first year Herring Gull. 2. Bill and head size and shape were not as heavy-appearing as in Herring Gull. Direct comparison with adjacent adult Herring Gull was very useful in deciding this. [...] 5. Size and pinker legs than Herring Gull are not sure characters, but lend support to identification as Thayer's Gull.

The documentation form by Ross Silcock is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Peter C. Petersen, and Robert K. Myers were submitted later. Other observers include Tom Shires, James Kovanda, Sandra Kovanda, Tanya Bray, Babs Padelford, Loren Padelford, B.J. Rose, and four unidentified other observers. | Elimination of similar species: The above description separates by direct comparison first-year Thayer's and Herring Gulls, the most similar species present. Thayer's may be confused in first year plumage with Kumlien's form of Iceland Gull, but the Thayer's had primaries slightly darker than the mantle (from above), whereas the opposite occurs in Iceland Gull (Lehman). Lehman also notes that some first-year Western Gulls may show translucent primaries from below in certain light, but these observations took place in excellent light at fairly close range. | The original documentation form event lasted from approximately 09:30:00/11:00:00.
