If a lyrebird is mimicking a chainsaw or truck, wouldn't that indicate the presence of those chainsaws and trucks?

I had to look this up because I though you were jesting. Turns out Lyrebirds can mimic nearly any complex sound: https://youtu.be/VjE0Kdfos4Y

I imagine it would depend on the lifespan, and travel patterns of a lyrebird, no? Eg, bird is making the chainsaw noise weeks or years after the loggers have gone, possibly in an entirely different area.
