This gull stood out among the thousands of herring gulls .( The white headed gull at the top). I thought it may be a casp but the paleish eye has given me doubts. In the field it did show a small ammount of hindneck streaking. I did not see the open wing.
Does a pale eye rule out adult winter caspian gull?
many thanks Steve
