China launches high-tech bird drones to watch over its citizens They're called Doves and they do not come in peace. June 24, 2018 https://www.cnet.com/news/china-launches-high-tech-bird-drones-to-watch-over-its-citizens/
Wow. That is just too bizarre. It flaps fake wings. Wow. Here in the US, we just use high-altitude planes and good lenses Plus IMSI catchers, of course. And who knows what else.
Looking at the pictures, I doubt this thing is operational to any significant degree. The thing in the picture looks like a child's toy from 20 yrs ago. However, I suspect that the US military has a number of "bird like" drones that look very real and it's only a matter of time (couple years?) before every government and even local police have access to an array of spy drones that are either translucent to blend into the sky or camouflaged to look like birds or even insects. Makes we want to invest in IR blocking window tinting.
