Lyrebird imitating construction work

This is Chook, our male Superb Lyrebird at Adelaide Zoo. We've had a lot of construction going on lately and Chook has picked up many of the sounds. We think we can hear the following sounds: Hammer, Chainsaw, Jack hammer, Lawn mower hitting sticks, Leaf blower starting, Power drill, Wood saw, Human voices, Two-way radio, Worker whistling, He makes lots of different bird calls as well.
