Busy bee

My whole bee is not sharp but the pollen on his leg is pretty focused. I forget every year how bloomin' hard these little critters are to get in focus!
Good Friday, intermittent sun, a bit of relaxation, a bit of gardening and some very healthy eating.
Can any of you name this shrub? I thought they were berries initially but they have actually opened out as little flowers. I wondered if it is part of the mahonia family? Any input gratefully received.
