On 31 October (4:00-5:00 p.m., overcast) and 2 November (4:50-5:20 p.m., clear) I observed a 1st-winter California Gull among the several hundred Herring and Ring-billed gulls swimming and roosting on the west side of Lake Calhoun (Minneapolis). The California Gull was with the mostly Herring Gull subgroup nearer the west shore (as close as 150 m). If you find the CAGU, please document it--thus far I lack information on wing or tail pattern in flight. Also present both days was a 1st-winter Thayer's Gull, and on 2 Nov. only, 1 adult Lesser Black-backed Gull and 6 adult Bonaparte's Gulls.
