Whilst clearing Ivy from our garden wall today, we uncovered a fireplace. Maybe the boundary wall was once part of a building? Maybe outdoor fireplaces were all the rage once (I think it's called camping).
This is a squirrel sitting on top of the base of my squirrel-proof bird feeder after having dismantled it. All the nuts cascaded down and the squirrel spent a happy hour gathering them up and burying them in some leaves.
