I have a neighbor, three houses down the street who has the same car alarm that the bird was doing. It is amazing that these birds can also mimic mechanical sounds like a camera shutter.
The lyrebird, which Sir David Attenborough meets on a log in a dense forest in Australia, is the bird world's best mimic. It can imitate 12 other birds. It does the whirring of a camera's motor drive and the click of a shutter. It repeats the engine of a car, and the din of a car alarm. It can even imitate the screech of the chainsaw wielded by the loggers coming to cut down its habitat.
