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.

[...] 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.

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. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing. Both kittiwakes eliminated by bill color, lighter mantle color, and differences in wing pattern. | The original documentation form event lasted from 16:17:00/16:42:00.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Only one other North American gull has a leading white edge to the upperwing- Bonaparte's. Size and jizz helped differentiate this bird from the Bonaparte's, but the dark underwing eliminated the smaller species. | The original documentation form event lasted from 12:30:00/12:33:00.
