Wasps nest!

When I was in the garden to trim back some of the hedges, I noticed that one of the bird boxes had a nest in it. However, it is not the sort of nest I had hoped for. There is a wasps nest!. They have certainly chosen a very sheltered spot. Since the nest is away from the patio I think I will leave them be. It was certainly busy and even just looking at the small part of their paper construction, visible through the box entry hole, it certainly is a work of art.
