Lesser Black-backed Gull

Yesterday afternoon, I found an adult Lesser Black-backed Gull along the edge of the artificial pond at Donaldson Park. At first it stood in the shallow water, and then it moved up onto the bank and stood there for a while. The mantle was clearly slate-gray, and its legs were obviously yellow in the afternoon sunlight. Light streaking on its crown and nape also indicates its identity. Oddly enough, there were no Great Black-backed Gulls present, or at least none that I saw. However, there were Herring Gulls and Ring-billed Gulls. This was a nice sighting to close out my county birding year.
