This strange looking thing is the Lyre Bird, the most efficient copycat in the animal world. In order to attract the females the Lyre Bird male produces the most elaborate, the most complex song he can, and he’s doing it by mimicking the songs of other birds around him. Bird experts never realized how well they reproduced the sounds around them until humans started invading their territory.
All of a sudden, there were sounds in the forest far more complex than any bird song and Lyre was quick to learn it. Make sure you watch this till the end to hear the most unusual sounds ever produced by a bird.
