This should impress you. It certainly impressed me, and my wife the roboticist. (you may be forgiven for thinking that the latter is harder to do):
All demos are faked, of course – but keep watching to 1:49, where Robo Raven passes the Turing Test. Or, more accurately, the Raptor Test.
PS: So, why is the Army funding robotic bird research? Why, I can’t imagine why we would want to do something like that.
