Imagine that you are hiking in an Australian forest. You hear many different bird calls, beaks snapping, and wings rustling. There must be many species of birds around right? Not if a lyrebird is nearby-all those sounds might be coming from just one bird! The lyrebird can imitate any sound it hears. Many Australians have heard lyrebirds singing the sound of chain-saws, car engines and dog barks. Supposedly, a lyrebird confused timber-mill workers by singing the sound of the mills whistle, causing the workers to quit for the day.
