CLOSED: What kind of gulls please?

They gather here in large number ... I believe they can be seen here at a local lake year roud, but larger flocks during winter.

...

Tough on the first pic, too small to see clearly! Probably mostly Ring-billed, maybe also some Bonaparte's and American Herring Gulls

Second pic (with the Great Blue Heron) is Ring-billed Gulls

Resin

Resin, so it could be a mixture of Ring-billed and American Herring Gulls? Above 2 pictures are taken at one location. Here is another pic.

New pic looks to be all Ring-billed Gulls (except for that Great Blue Heron of course!)

Resin

Many thanks Resin.
