You ever heard the varying cries and calls of the Kookaburra bird? Trust me, this is one of those questions you would know the answer to if you had. These particular birds have a call that is quite unlike any other bird you have ever heard.
Though these birds are indigenous to New Guinea and Australia, the Cincinnati Zoo and Botanical Gardens got their hands on one and decided to show us just how this remarkable bird communicates.
It may not be music to your ears, but it is quite an aural spectacle.
To me, it sounds like that is the sound the Joker would make if he were a bird. Just saying.
