Taken in a wood on the edge of Banbury, through the telescope (I was ten metres from the nest). She (I assume this was the hen bird) was completely settled, facing out of the hole in the beautifully constructed nest made from lichens, feathers and spider silk. Look away for a second and the nest became 'invisible'. I only saw it in the first place by following one of the tits returning with a white downy feather to add to the lining.
