At last, found one that sat still for more than half a second.
No interactions present.
well done, just another bird to add to my 'have not seen yet' list (which, incidently is growing by the minute)
At this time of year you will find them in mixed flocks of tits and soetimes other birds like Treecreeper or Goldcrest. It takes a lot of patience to get a good photo as you say they don't sit still very long.
