Деталі спостереження
My initial impression in the field was that this was a Slaty-backed. The bird seemed quite pale with paler greater coverts, but dark secondaries, wing tips, and tail. The pale head with collar seemed distinctive. The pale rump also caught my eye. I have asked a few people their opinion on the ID and I have heard pro Slaty-backed comments, however, they like me admitted they do not know much about this age of Slaty-backed. I am certainly open to discussion of this identification if it shows Herring Gull id traits.
