The video might be NSFW if you have a weak stomach.

This crane was walking around free at the Featherdale Wildlife Park in Sydney, Australia. As he's walking passed a cage holding an eagle, he decides to start messing with the eagle.

I think this is where the term "bird brain" comes from. Why he would think he had any chance against this eagle is beyond me.

You'll see the crane snap it's long neck in an out of the cage a couple of times, just enticing the eagle. The next time wasn't so good for the long-necked avian as the eagle grabbed the crane's head with it's sharp talons.

The video cuts away as the people watching begin to freak out, so we can only continue the story in our heads. I imagine it wasn't so good for Mr. Cocky Crane.
