Is it a Bird?

Science imitates nature and the result is art. German inventors have devised a rather beautiful mechanical bird that flaps, flies, soars and returns to land. It's interesting to contemplate humans one day flying in this way, but the lifting power required to get a human off the ground would probably be prohibitive. And the wingspan would be titanic. Armies around the world must be looking at this metal/composite bird as yet another potential surveillance robot.
