Check Out The Awesome Calls of This Bird
The sounds are unreal coming from this bird. The Lyrebird is the only bird that does not have it's own call. Each bird has a unique call made up of the sounds in it's vicinity, including other birds, chain saws, camera motors and clicks and anything else it hears. No two birds have the same set of calls.
These birds make these calls when courting the female. They mostly reside in Australia.
