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.

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 Ross Silcock is the only one submitted and forms the basis of this record. | Elimination of similar species: See attached discussion. (After writing my field notes at the site of observation and returning home later I found the stnadard field guides most unhelpful. Dunne et al's discussion of Ferruginous was tremendous, indicating variation in Ferruginous Hawks, and especially in discussion of flight characteristics, 'jizz', and behavior [...] The only possibility which is realistic to consider is Redtailed [sic] Hawk, or possibly Rough-legged Hawk. While similar in 'jizz' to a rough-leg (long tail, flight with 'crooked' (=osprey-like) wings, darker mottling underneath, longish wings), Roughleg can be eliminated by the following characters - absence of characteristic underwing pattern, including significant wrist mark (Ferruginous should show this to some extent according to Dunne et al, but I did not see it; remember I did not see the underparts well), and method of hunting-I have never seen a roughleg fly this low over the ground for this long (about a mile) - much lower and more consistently so than a harrier. Regarding elimination of Red-tail - I really think it is easier to eliminate Red-tail than rough-leg based on 'jizz'. The tail was too long, was never spread, and wings were long than Red-tail's. Tail pattern and 'three points of light' combination also is never seen on a Redtail [sic], especially when viewed from above. (The similarity to Roughleg [sic] in pattern can be seen in the front end paper in Dunne et al). Habitat and behavior also are important - while Redtails [sic] are very common in Fremont County, they are definitely not common on the open Missouri bottomlands. Redtail [sic] is a bird of edge habitat. I always look closely at any buteo seen from October to April on the open bottomlands. I have never seen any other buteo fly as low to the ground for as long as this bird - when i say low, I mean 1-2 ft above the ground. At no time was the bird higher than 6', and that was when perched on possibly the lowest post for some distance. Even a Harrier will rise and fall while hunting. This bird stayed low, in the manner of a hunting Golden Eagle (which I have seen in Western Kansas) - a point also mentioned by Dunne et al. Another point noted by Dunne et al and also shown in my sketch (purposely!) and, mentioned in my field notes was the osprey-like crook in the wings-while flying low over the ground. Dunne et al note that this is characteristic of a hunting Ferruginous. | The original documentation form event lasted from 15:30:00/15:45:00.

The documentation form by Ross Silcock is the only one submitted and forms the basis of this record. Other observers include B.J. 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.

[...] 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.
