Ernzen, Peter	Little Gull	Black Hawk Lake	[...] 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.

Report of committee for selection of "State Bird", April 30, 1927	Reports	Ornithology--Societies, etc State birds	1927-04-30	N/A	Manuscript, graphic, and printed material	A report from the committee that was appointed at the Iowa Ornithologists' Union annual meeting in 1926 to investigate the feasibility of selecting a state bird for Iowa. The plan from the committee suggests having members of the Iowa Ornithologists' Union nominate five birds which would be narrowed to a final nomination of five to six birds. The final nomination of birds would then be submitted to the school children of Iowa for them to vote and ultimately select the state bird. In order to cover the expense of this campaign, the committee suggests increasing membership dues by $1.00 per member.	Iowa Ornithologists' Union Palas, Arthur J. Spiker, Charles J.

Other observers include Don Stolz, Carole Stolz, Eugene Armstrong, Eloise Armstrong, Pam Allen, Reid Allen, Ann Johnson, Jim Dinsmore, Jim Fuller, Bob Cecil, and Aaron Brees. \| Elimination of similar species: My experience and references of Buff-bellied Hummingbird suggest that the cinnamon color, extent of this color toward the throat, cinnamon rump/back, and white eye spot do not fit this species. I believe that the features shown in the photo of the Arizona 'mystery' bird in Field Notes are a perfect fit for the Des Moines bird. I do not know of specific information on bird trafficking in Iowa. We had a Yellow Grosbeak north of Des Moines in December 1990, the origin of which was never explained. \| The original documentation form event lasted from 07:50:00/08:40:00.

Other observers include Doug Rose, Roger Rose, and Ken Lowder. \| Elimination of similar species: Because of the fairly small size and conspicuous dark spot behind each eye, the bird must have been a Bonaparte's, Little, Common Black-headed, or Ross' gull, or a kittiwake. Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers.
