Advanced bird drones must be born secret technology. It makes little sense how so much can be understood about birds and yet there is no perfect bird replica on the market aside from these pared down maker lab tier efforts. And indeed, lending further credence to the born secret idea is that the CIA has been experimenting on bird drones since at least the 1960s (1), and this was only revealed to the public in 2013. The state of the art must be so far advanced. What a prize for an intelligence agency to be able to create a surveillance system where it does not matter if it is detected on radar, or visualized at all because it looks exactly like indigenous bird populations. 1. https://en.wikipedia.org/wiki/Project_AQUILINE https://en.wikipedia.org/wiki/Project_AQUILINE
