We've reported in the past on SID robots used scare birds off power lines and a solar-power, floating robot that scares birds away from aquaculture ponds. Now, a company called Intercept Technologies has developed a remote-controlled, powered, ornithopter disguised as a giant falcon, called Robofalcon. It's used to scare large birds such as Canda Geese away from airports. Though it's not really an autonomous robot, it's still an impressive feat of engineering that will be of interest to anyone who has worked on flying robots. There is an ABCNews article on the product and a Popular Science article with more photos of the Robofalcon.
