Bird ID please

[Chocky]

Her is a little bird I captured today high up in a tree.
I thought at first it was a Dunnock but some thing about him isn't quite right for a Dunnock . I could be wrong
Looking at the last photo which unfortunately isn't really good . The bird appears to have a White rump. I have never seen a Dunnock with white any where.

No doubt in my mind Chocky, a Dunnock.

[Chocky]

He is. Thank you His legs kind of give him away don't they ?
But where did he get his white em rump . Unless maybe he light and his position.

The cheeks are very distinctive.

[Chocky]

Oh yes they are
I thought it was at first mainly because of his legs and his head is not so blue.
I'm going to upload him into the gallery later.
Thank you
