The bigger advantage to building an ornithopter from a deceased bird is camouflage, because in the air it will look more like the real thing and, hopefully, is more inclined to be ignored. It might not excel in aerial combat, but a dead bird drone could potentially be a very useful espionage tool, whether used for military purposes or as a way for scientists to study and observe other wildlife while ensuring their behaviors remain natural and undisturbed.
