Anne Elliott's photos with the keyword: Herring Gull?

I'm really bad at Gull identification, but I think this might be a juvenile Herring Gull. Somehow, I just can't get "into" Gulls, though the young ones really can be quite attractive with all their brown markings. Taken at Pearce Estate on 27 August 2013. No, I think I was wrong, and that this is in fact a juvenile Ring-billed Gull.
