Bees galore!

The Mahonia was covered in bees today - the buzzing was very loud! Most of them were Honey Bees and I did manage to get a couple of photos - very difficult, they don't stay still!
I thought this one had something wrong with its back legs but on Googling I found out they collect pollen and nectar on their back legs forming 'saddle-bags' held in place by the hairs on their legs.
