I went to Walden after the posting of the common tern today. It is difficult for me to determine if it's a Forster's or common however. The underparts are white, and the tail longer than the wingtips, but the primaries are dark. I never saw it in flight but it was on a good perch in Cottonwood and I was able to study it with my scope. I am more comfortable calling it a Forster's. Any other votes?
