Skulking

During a brief spell when the feeding (birds as opposed to humans!) area of the patio was empty, I noticed this little one skulking around  under the bird table. I thought at first it was a young Song Thrush, as we think they have nested close by, but didn't think a Thrush would get this near to the house and other birds - they like open spaces. 

So we have decided it is either a young Robin or a young Dunnock and have gone at the moment with Dunnock. Anyone any ideas? 

A lovely day, if a bit windy. And now we have a sunny evening.
