Viewers of BBC2's Autumnwatch complained last night after host Bill Oddie broadcast video film shot at his home in Hampstead. It showed a grey squirrel lying dead next to an electric cable it had tried to bite through. Oddie, 67, was heard laughing as he told viewers: "It's not a sleeping squirrel, he's literally dead," and joked: "You squirrels, don't do it. Better red than dead."
