Dear Cobirders, Nick Komar will post more on this topic later including photos, but I thought I would just quickly post that the bird initially identified as a Black-tailed Gull yesterday was relocated this morning (12/26) at Thomas Reservoir. The bird was observed by many and photographs were obtained that strongly suggest that this individual is, in fact, an aberrant California Gull with retained, strong, black second-cycle retrices on an otherwise third-cycle bird. I'd like to thank everyone who came by to see this neat bird. I hope that folks also had a chance to stop by other nearby reservoirs and see the wonderful gallery of Gulls on display today including, a Glaucous Gull, some variety of Glaucous-winged hybrid, immature Lesser and Greater Black- backed Gulls, many Herring Gulls including at least one individual that looked good for Vega Gull, and the usual suspects.
