Is it a Tawny Mining Bee?

Today, I have seen lots of different bees on the ceanothus.

If you're interested, they included: Bombus pratorum, Bombus hortorum, Bombus hypnorum and three different types of solitary bees. I'm not nearly as confident guessing the identity of solitary bees as I am identifying bumblebees. This looks very like a Tawny Mining Bee, but I've seen other fatter ones in the past few weeks, so I'm not sure...

Oh, and I've found my camera!!!
