A foul-mouthed parrot has taught two other birds to swear, to the annoyance of the owner of a wildlife sanctuary. Barney, a seven-year-old macaw, has been swearing so often in front of a pair of African greys, called Suzanne and Charlie, that they have picked up his language. Jeff, the owner of the Warwickshire Wildlife Sanctuary, said: “They just sit there swearing at each other now. It sounds lke a builder’s yard.” In 2005 Barney was placed in solitary confinement after he told the local mayor to *bleep* off.
