I'm still in confusion over telling apart 1st winter Yellow-legged Gulls and 1st winter Herring Gulls, would anyone have any advise. My knowledge only extends as far as Herring Gulls tend to have a serrated edge to the tertials whilst YLGulls have no serration on the tertials, I'm also not sure whether this is a reliable method for telling the species apart. I'm fairly sure the first and last images are of Herring Gulls but I am unsure about the second image, is it another 1st win. Herring Gull?
Any opinions welcome,
Samuel
