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.

Dinsmore, Stephen J.	Little Gull	Sandpiper Recreation Area	Saylorville Reservoir, Polk Co.-seen off Sandpiper Beach Recreation Area	seen flying over large reservoir with several Ring-billed Gulls	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 and Reid Allen were submitted later. \| Elimination of similar species: The bird was obviously too small to be one of the larger gulls, like a Ring-billed or a Herring gull. The very pale mantle, dark spot behind each eye, and lack of black on the top of the primaries eliminates Franklin's and Laughing gulls. The black underside of the flight feathers, pale gray mantle and wings, white wingtips, and rounded wings eliminates Bonaparte's and Sabine's gulls and kittiwakes. The square tail and wing pattern eliminates Ross' Gull. The smaller size, black underside of the flight feathers, lack of a white "wedge" on the upper surface of the outer primaries, rounder wings, and lack of black on the upper surface of the primaries eliminates Common Black-headed Gull. \| The original documentation form event lasted from 09:30:00/09:34:00.
