Gulls are Back

OK, here in Bucks County, PA I don't think we ever lose the gulls entirely--you can see a few Ring-billed Gulls up at Lake Nockamixon even in summer. But the wintering gulls are starting to trickle back in. Today I had 3 Lesser Black-backed Gulls and one Great Black-backed Gull. We still don't know where these lessers go for the summer, which as far as we know aren't nesting in North America.
