Stuart McNae has had to change his mobile phone ringtone five times – because his parrot Billy keeps copying them.
The parrot waits until Stuart leaves the room, mimics the sound of a call – then laughs when he dashes back to answer.
Sue tells me that a parrot in a house nearby her when she was a child learned to mimic the mother calling for her kids – then laughed when the kids came running back into the house.
It should also be noted that there are wild parrots in Los Angeles who have learned to imitate car alarms.
