I managed to finish the mother bird today and add in the last few shadows so here is the finished painting and the story that goes with it.
Life at the moment is more than a little crowded in the barn swallows nest. The babies are growing fast. Their baby down has almost gone and they will soon be ready to leave the nest. The lack of space at the moment makes feeding time especially challenging. Each time a parent returns there is a tussle for the prime feeding spot as a sea of mouths opened wide.
