The tits abandoned this nest box when the wasps took over, but at least it provided a nesting place for some form of wildlife even if it wasn't what I would have chosen.
this one was successfully used by a family of great tits
And this by a house sparrow family
and again this one was used by house sparrows. I love all the feathers in this one!
They have now all been emptied and returned to their positions ready for next spring!
