There is a Lyre Bird at my local zoo (Adelaide) that has taken to imitating the construction workers and their tools which are being used to construct a new panda exhibit nearby.
The sounds you should be listening for are as follows:
Electric drill
Handsaw
“Hello Chook”
Chainsaw
Water drops
Truck reversing
Post-mix drink being poured
2 way radio chatter
Jackhammer
It makes bird sounds too:
