Apologies for posting late. An immature white-winged gull, possibly a Thayer's, was on the reservoir Sunday, along with several hundred other gulls and a definite Kumlien's. There has been quite a bit of debate on various facebook groups, and I would welcome more opinions. I'm going to try to re-find the bird tomorrow to get better pictures, as the ones I've got are distant and overexposed.
