Late this AM, Catherine Temple, Rick Welle and I spent about 30-45 minutes glassing and scoping what appears to be the gull first seen by John Hanna in late January in the same Swallows Park, Clarkston location.
The bird was with a mixed group of 150+/- Ring-billed, California Gulls with a couple of Herring Gulls and at least two 1st Winter Thayer's Gulls.
Subject bird was similar in size to the California Gulls.
It has pink legs/feet,. a rather smallish two toned bill with a dark tip, a rounded head, an overall pale tannish/whitish appearence, on the one occasion we were able to see it open it's wings it showed a white under side to the wings.

The bill appeared smaller when it was next to the 1st year Thayer's Gulls.
Photos were taken at considerable distance and the bird was on the far side of the mud island with willows intervening at times.
