Otto, Rebecca Otto, William	Black-legged Kittiwake	Lake Manawa State Park	[...] at the dredge ponds near Lake Manawa, Council Bluffs, Iowa.		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.

Eventually one appeared within 20 ft of the tractor that was different. During its first pass I noticed its size between a Franklin and Ring billed, a dark spot and streak behind the eye and that the upper wing front was blackish.

Baum were submitted. Other observers include Mary Lou Petersen, Cal Knight, Bernie Knight, Tom Rockwell, Lewis Blevins, Brian Blevins, Don Moeller, Walter Zuurdeeg, Daryl Tessen, Doug Rose, Alan Grenon, and many unidentified observers. \| Elimination of similar species: (A) Greater black backed - Gull in question has slaty - gray saddle rather than coal black. And Gull in question is same size as Herring Gulls; Greater black-backed would be much larger. (B) Lesser black backed - Gull in question has pink legs and feet, and has much more white on primaries. (C) Western - Gull in question has considerable white on primaries, and does not show dusky trailing edge to underwing. Also has broader white trailing edge to upperwing than would the Western. (D) Herring Gull - dark race - no experience with this, but those shown in Harrison do not show as dark a saddle as Gull in question, nor as much white on primaries. \| The original documentation form event lasted from 15:00:00/15:30:00 on February 12, 1989, 12:15:00/12:45:00 and 16:00:00/17:30:00 on February 14, 1989.

Wright, Rick	Lesser Black-backed Gull	MidAmerican Energy Ponds	IPPD Settling Ponds, Pottawatamie [sic] Co., Iowa		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.

Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. \| Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. 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.

Other observers include Steve Dinsmore, Paul Martsching, Pete Wickham, Mark Brogie, Lewis Blevins, Corey Blevins, Brett Ashford, and Dale Dickinson. \| Elimination of similar species: Glaucous Gull eliminated by size, wing extention [sic] well beyond tail. Flight, headshape, all emphasized by direct comparison with Glaucous Gulls. The next afternoon Bill Barker compared this bird to two different sized Glaucous Gulls and it was smaller than the smaller Glaucous Gull. Plumage lighter than Glaucous also. \| The original documentation form event lasted from 11:40:00/12:10:00.	Iowa Ornithologists' Union \| MS 166	11	4

Thayer's Gull	Saylorville Dam	Above and below Saylorville Dam	Open water, rocky shore and ice covered pond.	The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. \| Elimination of similar species: [...] Nearly the same size as an immature Herring Gull, but neck seemed thinner, head smaller. Bill was same length as a Herring Gull's but was blunter, not as strongly hooked. [...] The primaries were not nearly as dark as immature (1st year) or 2nd year Herring Gulls and was of a much different color than the black color of that species. Primaries and tail were nearly the same color. [...] In flight this bird could be easily picked out from the immature Herring Gulls at considerable distances. Using 7x35 binoculars the beige color of the upper surface of wings and translucent underwing could be detected as far as three-quarters of a mile. There were also three other birds that resembled this particular bird though they appeared darker on the upperparts. However I was unable to get close observations of these birds. The bird I observed closely and documented had one primary feather missing and aided in tracking the bird from day to day.	Iowa Ornithologists' Union \| MS 166	11	3

Kent as dictated to Carl Bendorf is the only one submitted and forms the basis of this record. Another observer was Carl Bendorf. \| Elimination of similar species: imm. Herring Gull. The second year Herring has a light bill with black tip and more contrasting black and white pattern to wings and tail. The first year Herring is much darker, has a more bulbous, hooked bill, and lacks the definitewhite [sic] window in flight. \| The original documentation form event lasted from 08:15:00/08:30:00.

Ross	Thayer's Gull	Lake Manawa	Lake Manawa		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.	Iowa Ornithologists' Union \| MS 166	11	3

Moore is the only one submitted and forms the basis of this record. Other observers include Russell Hays, Tom Kent, Tom Shires, Tom Staudt, and many unidentified other observers. \| Elimination of similar species: Ring-billed Gull and Herring Gull, see above. The Ring-billed Gulls were seen in direct contrast to these three birds and were definitely much smaller birds. The Herring Gulls (first year birds) that I have seen have more of a contrast between the rump and back and upper wing surfaces and none that I remember showed the whitish trailing edge on the tail. [...] The three birds seen were about the size of Herring Gulls in typical first year plumage. They were obviously large gulls of the genus Larus with a noticeably larger size than the Ring-billed Gulls and one Bonaparte's Gull that were next to the three larger birds. [...] There were no Herring Gulls nearby with which to make a comparison of size and coloration. The bills of all three gulls were black did not seem as heavy or bulky as the bill of a Herring Gull. \| The original documentation form event lasted from 08:10:00/09:30:00.

Kent is the only one submitted and forms the basis of this record. Other observers include Carl Bendorf, Mike Newlon, and many unidentified other observers. \| Elimination of similar species: Photographs taken at the first encounter with a Celestron 750 mm lens demonstrate the size difference, the bill and head shape difference, the lighter overall color, and the window in the wing. An adult Herring was in the photo with the Thayer's on 7 Nov and imm Herring were photographed on 10 Nov for comparison. \| The original documentation form event lasted from 09:25:00/09:50:00 and 11:00:00/11:20:00 on November 7, 1981 and 07:30:00/08:30:00 on November 8, 1981.

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.
