The birds have fallen into a deep winter hush. Only a few fieldfares were clacking as I tramped through the snow towards Biggin Hall. The ruined barn where a barnowI buzzed me back in 2008 has been done up as a shooting lodge, and the owls will have to find a new place to roost in spring. It has a lovely view looking across to Glapthorn and Short Wood on the other side of the valley, and I was very taken by the door bell.
