I'm hopeless with gulls, unless they're in full adult plumage. Are these two young Common Gulls? I haven't seen any adults in the area.
For size comparison, the bleached-out bird in the foreground here is definitely a Herring Gull.
Not too sure but they look like yellow legged gulls to me but I would wait for someone with more knowledge I just looked at my ID book.
