A pair of Coal Tits were busy gathering nesting materials at Tyttenhanger.

Beautiful picture - you must have been quick to catch it sitting still - the ones round here are always flitting about!
They certainly seemed to be concentrating on the job in hand rather than being concerned about my presence. I was kicking myself actually because prior to getting this shot one was collecting material approx 10 feet away - just wasn't quick enough with the camera :-)
