Double Wildlife Pics!

Firstly, have a main picture of a squirrel. Mostly grey, but with red cheeks and paws. Half breed?

And in the extras ..... found this on pavement on way into town. Bee at back was normal size, bee at front giant! I have no idea if this was mating, or the bee at the back was trying to push the bee around. So is this a queen bee? Is it the end of the bee season for some bee species? (I really don't know much about bees.) Anyway, having no idea I left them ...
