That ruffed grouse video is great but does not really do justice to how startling that sound can be. Imagine walking through the woods, no one around, and all of a sudden it sounds like a lawn mower starting up very close to you. It is unbelievably startling, even if you know what it is.

As a horror film fan, I was thinking combustion powered chainsaw.

The lyrebird can imitate a chainsaw -- among many other things. This is from the BBC's Life on Earth.

Note that there is a bit of subterfuge in this -- some or all of the lyrebirds mimicking were in captivity and would have heard these unnatural sounds much more than the typical wild bird.

That’s amazing, thanks for the share! I’m one of today’s lucky 10,000.

Excellent! I thought everyone had seen this, indeed.

Don't fall for the parody though ...

Nor this apparent imitation of the clearly inimitable Big Shaq:

Wow thanks. The camera shutter and car alarm were something but that chain saw sound is incredible.
