Tasmin a young married blue tit is about to become a mother. When a man puts up a sign near to their home next to the stinging nettle bush. Tasmin has a feeling that her nest and the future of the New River is under threat. As blue tits can't read their friend Cora Coo, a wood pigeon suggests they ask the cemetery owl for help as everyone knows that owls are wise and all wise beings must be able to read. Terry, Tasmin's husband is reluctant to go and talk to the owl, as he has never left the New River and all songbirds know that owls have a taste for small birds. Will the Cemetery Owl help them? Or will the fate of the New River rest in the hands of a much smaller bird?
