Still not convinced its an owl. I googled The Eye Show 2009. Bird display. Owls. Eagles. My name....just kidding. Owls usually have a facial disc (its how they hear things) which this one seems to be missing. I did spy a Brown Snake Eagle, and African bird that looks allot like this, though not a bird I've ever heard of being used in a Bird of Prey display.
Oh, I love a good mystery.
