The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] I ruled out other gulls, especially A [sic] young Herring Gull (1st yr) because of the location of the white (belly & wings) as well as the deep rowing flight. In addition, I had the opportunity to observe the Pomarine Jaegers earlier this fall at the same location and the markings were similar, except this bird was darker with a white belly. | The original documentation form event lasted from 14:40:00/14:40:25.

[...] south east corner of Blackhawk Lake in Sac Co.
|
|
The documentation by Peter Ernzen forms the basis of this record. A documentation form by Jim Fuller was submitted. | Elimination of similar species: [...] The other five hooded gulls were eliminated for a variety of reasons. Franklin's and Laughing Gull would be larger, darker mantled and have a prominent eye ring. Sabine's Gull would've had a bicolored bill, forked tail and different - white triangular - pattern to its wings. The larger Common Black-headed Gull looks like a larger version of a Bonaparte's Gull with a brownish hood and a red bill. The associated Bonaparte's Gulls were darker mantled and larger. The wings were more angular in appearance with a white leading edge and black wing tips. I have observed all but the Laughing Gull - though the Sabine's Gulls were immature, the distinctive wing pattern is present in both adults and immatures - and feel confident in calling this an adult Little Gull. | The original documentation form event lasted from 10:15:00/10:30:00 and 11:00:00/11:08:00.

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.

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 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 Babs & Loren Padelford is the only one submitted and forms the basis of this record. | Elimination of similar species: At rest, the bird had a very slender and streamlined appearance, not stocky like that of a Franklin's Gull. The head had no trace of a dark hood. The head was the same color as the rest of the body except for lighter areas around bill, on forehead and top of the head. The bill seemed longer and more curved than a Franklin's, but difficult to say with no Franklin's for comparison. | The original documentation form event lasted from 10:15:00/11:05:00.

I saw one Franklin's this spring with a very narrow white band in the primaries. If this isn't a Laughing Gull, it's an aberrant Franklin's. It seemed to be in a very neat breeding plumage, not a young bird. | The original documentation form event occurred in the afternoon for around two minutes.

Skuas are easily eliminated by their larger size, heavier bill, and more prominent white patches on the wings. Long-tailed Jaeger is eliminated by the presence of a white crescent on the upper surface of the wing. Pomarine Jaeger can be eliminated by its larger, heavier body size, more prominent white crescent on the wing, presence of white greater underprimary coverts, larger-headed appearance, heavier bill, and general lack of rufous color on the body. | The original documentation form event lasted from 16:22:00/16:51:00.

[...] We re-examined the bird and I noted the following - a shorebird about Pectoral SDP. size but a little more elongated + less plump. [...] Bill similar to Pectoral SDP but straighter + a little heavier. [...] Also noticeable was dark coloration at bend of wing, when bird feeding. Latter was deliberate, rather like Dowitcher, head often under water. [...] (2) Difficulty of eliminating Red-necked Phalarope - I believe this is achieved due to the following (a) Red has much thicker bill (b) Red is significantly larger } Size comparison with Lesser Yellowlegs at IPL indicated this bird was not a small Phalarope. Bill was very heavy - as heavy or more so as a Pectoral's bill. | The original documentation form event lasted from approximately 12:15:00/13:30:00.

Rose, Roger Rose, and Doug Rose. | Elimination of similar species: [...] It resembled a Pectoral Sandpiper, but differed in the following ways: the crown was streaked, and showed noticeable rufous coloration in the feathering; the off-white superciliary stripe was lengthy and broadened towards the rear; the breast markings were dense as in a Pectoral but did not show a clearcut ending at the whitish belly, but instead ended indeterminately by gradually fading out. [...] Once ready to record, we flushed the bird and it gave a soft series of notes, somewhat like a Lesser Yellowlegs, but rather flat and unmelodious. This call was most unlike the harsh, grating call of a Pectoral Sandpiper. [...] Plumage, time of year, call upon flushing, and key plumage differences from Pectoral Sandpiper, cited above, led us to identify this bird as an adult Sharp-tailed Sandpiper. | The original documentation form event occurred around 10:30:00.

The documentation form by Tom Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] I noticed a bird the same size as a killdeer next to it but chunkier. I knew it was unusual and also knew it was a Red Knot from the breast and the bill size which I estimated as twice as long as the Killdeers bill and Dowitcher - bill was shorter than dowitcher and dark back. I tried to think of other shorebirds it could have been and the dowitcher species was what I could imagine, but its bill was too short. | The original documentation form event lasted from 19:30:00/19:35:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Pam Allen, Jim Dinsmore (2x), Mark Proescholdt, Beth Proescholdt, and Tim Schantz were submitted later. Other observers include Jim Fuller, Ann Johnson, Reid Allen, and unidentified other observers. | Elimination of similar species: The fairly large size and gray and white plumage eliminates all shorebirds except Sanderling and winter-plumaged Dunlin. Sanderling is eliminated by smaller size and different bill shape. Winter-plumaged Dunlin is eliminated by different bill shape, slightly smaller size, and different tail pattern. | The original documentation form event lasted from 17:20:00/18:48:00.

The documentation form by Peter Ernzen is the only one submitted and forms the basis of this record. Other observers include Joshua Ernzen. | Elimination of similar species: [...] Whimbrel was eliminated by size, color and bill size. The whimbrel should have been slightly smaller to about the same size as the marbled godwits. The brown body and cinnamon wing linings did not fit whimbrel either. The bill size is variable with shorebirds, however the great length of the bill was more suggestive of the long billed curlew. The call heard does not fit the description for whimbrel in my National Geographics [sic] Field guide to Birds of North America. Three outside possibilities the far Eastern curlew, Eurasian curlew, and bristle thighed curlew were eliminated as well. The far Eastern curlew size is about the same as that of the marbled godwit. The bird also has white wing linings with dark barring. The barring would be hard to see, however the lighter color would be distinguishable. The Eurasion [sic] curlew was eliminated because this bird would have a white rump, and white wing linings. The bird I saw in flight turned and twisted. I did not notice any white markings on the rump. The bristle thighed curlew is much more similar to the smaller whimbrel and would be eliminated by small size, shorter bill and call - "chu-a-wut". | The original documentation form event lasted from 19:50:00/20:00:00.
