Thanks to Glenn for posting. I had a MEW GULL on the beach at Lighthouse Point just before sunset this evening. It was with some 400 RBGUs that had come in to roost after plankton feeding. The flock was soon flushed out to the harbor by a beach walker. Still trying to figure out which subspecies involved. My very rough estimate was about 2,000 gulls plankton feeding in the vicinity. These plankton-feeding gull flocks can be incredibly ephemeral, so chasing an individual is tricky at best. Nick Bonomo Wallingford, CT www.shorebirder.com
