Observed in flight, top of wings were consistently dark grey with black on the tips. It finally came in closer so I could get a better look, bill has red spot on it (poor pictures from my phone), some streaking on back of head. Maybe a little larger than the ring billed gulls, but much darker on the back. Looks different than the one reported here recently, this one appears to be older.
