Johnson, Ann	Thayer's Gull	Saylorville Dam	Saylorville Lake, Polk Co., IA	dam on Des Moines River forming reservoir	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The primary identification was done through the size and shape of the head. Other similar gulls do not share this "dove head."

Another documentation form by Diane Porter was submitted. Other observers include Beth Brown and Tim Schantz. \| Elimination of similar species: Herring Gull was eliminated by the light and uniform body color, brown as opposed to blackish primaries and tail band, bill and head structure, and lack of any color to the underside of the primaries. Iceland Gull was eliminated based on the darker secondaries and wide, brown tail band. \| The original documentation form event lasted from 10:20:00/10:40:00.

Other observers include John Cecil, Tom Kent, and Francis Moore. \| Elimination of similar species: Only probable similar species is Herring, which has contrasty wings - dark trailing edge and darker wingtips. The Thayer's were obviously a lighter shade of brown than any Herrings present. I judged these birds to be somewhat smaller than any Herring. I could not totally rule out first year Glaucous-winged. According to NGS, Glaucous-wing has less mottling or scalloping. The Keokuk birds were obviously mottled. \| The original documentation form event lasted from 11:05:00/11:30:00.

Other observers include Corey Blevins, Lewis Blevins, and Jennifer Anderson. \| Elimination of similar species: Herring Gull -> eliminated by the light brown color continuous all the way throughout the wingtips, thus there was not a darkening towards the wing tips. The mantle was also lighter than those of the nearby Herring Gulls. \| The original documentation form event lasted from 14:30:00/14:50:00.	Iowa Ornithologists' Union \| MS 166	11	3

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.

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.
