My next door neighbour persists in putting out large amounts of food for the birds, eaten by pigeons, seagulls, crows and other large birds. Their flight path crosses my garden, and they leave large deposits over my shed, garden furniture and patio in their wake. She is already in dispute with the neighbour on the other side, to the extent of police involvement and I don't wish to join in, but these birds are a pest and I wish she would stop feeding them. But as she is a woman who has never knowingly done anything out of consideration for anyone else, including her husband and children, that is unlikely to happen.
