Common or Ring-billed gull? (1 Viewer)

Well-known member
assumed this was just another common gull, but someone on Flickr has suggested it is a ring-billed gull. It was taken in Co. Antrim, N. Ireland, a year ago.

It's a second-winter RBG, note the lack of white tips to the primaries. The age of the bird would explain why it hasn't developed the nice bright yellow tones to the legs and bill and possibly poorly developed white irises of a full adult. It's difficult to properly make out the eye due the angle of the head but they don't look completely dark though.
Btw. there has been a RBG x Common Gull hybrid knocking around the North for a while now which was born and ringed out on the Copelands I think but that bird should be a full adult at this stage.
