Ever seen a baby pigeon? Not a tiny, fluffy one. Not even one nicking chips outside the station. Suspicious, isn’t it?

When a pigeon invades Mr Morton’s bookshop, Brian finds a book asking why nobody ever sees baby pigeons. There’s a sensible explanation involving squabs and nests. Then there’s Dr Gerald Peck’s theory: a secret pigeon factory beneath Trafalgar Square, flat pigeons, an Inflation Department and a rigorous course in chip theft.

Join Mr Morton and Brian for a bonkers investigation in this episode of Mr Morton’s Barmy Book of Bonkers Bits, the children’s comedy podcast where facts are questionable and the truth has a habit of getting rather silly.
