Holy crap, he's scary looking!
My understanding, as far as ratites go, Emu's are the nicest and casowarys are scary for zookeepers if they have to mess with them... Not too distantly related to the Terror Bird if I'm not mistaken... Apparently the problem is that they are easily spooked but, rather than running away, they attack whatever startled them... Beautiful birds though.Yep, those things will hurt you!
