Violent yellow chickens date to prehistory

Paleontologists at Yale and the Smithsonian Institution have discovered that Xenicibis, a member of the ibis family that lived about 10,000 years ago and was found only in Jamaica, most likely used its specialized wings like a flail, swinging its upper arm and striking its enemies with its thick hand bones.

According to the lead Bulldog on the research team, Nicholas Longrich, "No animal has ever evolved anything quite like this. We don't know of any other species that uses its body like a flail. It's the most specialized weaponry of any bird I've ever seen."

Clearly this quack has never seen Family Guy. Read more about the discovery here.

This is one of the coolest videos ever

My favorite is the Goshawk, starting at 1:52. Enjoy.
