The funny thing about a homeless person attacking a cage and eating a rare bird is the fact that there are so many other animals in the zoo that are much tastier. Japanese Crane is a little stringy. I myself would have went for a Koala Bear or something harmless like that. Heck, I bet Chimpanzees taste pretty good. Like I always say, "That which doesn't kill you, tastes pretty good on a stick."
Or, so I've been told. ;~)
