I put up four additional boxes in the spring, made by our neighbour Bill. These are lovely, solid wood and neatly made, as you'd expect from a builder. Three are tit boxes, one is open fronted, supposed to be suitable for robins or blackbirds. They are ranged round the south side of the picnic glade.
This winter, I have had help from two Duke Of Edinburgh Award candidates, doing their volunteering with Nettleham Woodland Trust. They were happy to get up the ladder and bring the boxes down then record the contents.
