An elderberry treat in the rain

I saw this bird flitting back and forth into the heart of the elder bush which grows over the fence we share with our neighbour. The pigeons have been pecking away at the berries since they formed some weeks ago. But I think they have now ripened and are a sweet change from the other staple foods available in such wet weather. The rain drops were falling off the bottom of the berries.

I don't actually know what type of bird it is, I thought at first it was a female blackcap, but now I'm not sure. It was fairly shy and didn't come into the open too often. Hence I had to wait a while for it to leave the shelter of the dense growth near the trunk of the elder bush.
