LBJ

Actually a Dunnock, I was watching two of them flitting around for half an hour or so with something in their beak. We usually see them on the ground and to see them in the conifer caused some doubt. John was working with our knowledgable neighbour and he confirmed as a Dunnock. More than that he couldn't say.

From internet:
A small brown and grey bird. Quiet and unobtrusive, it is often seen on its own, creeping along the edge of a flower bed or near to a bush, moving with a rather nervous, shuffling gait, often flicking its wings as it goes. When two rival males come together they become animated with lots of wing-flicking and loud calling.
