Adult. Probably the same bird that J Uffman had at Riverlands yesterday, but not positive. Roosting with the other gulls in the middle of the lake. Dark mantle caught my eye first and as I watched it, the size was obviously smaller than the adjacent RBGUs and the bill, much shorter and thinner. Poor digiscopes, but I think they are still identifiable.
