The answer can be found at 24 seconds. Take a look at the shadow on the house… It looks like a tiny RC controlled plane with a GoPro attached to it.
They put GoPros on the birds, yes. (:
Haha, laughing my culo off! Great pic!
The video was filmed with a camera which was placed on an RC Plane. .
Video was taken with a drone and in about 1:30/min you can see shadow from the drone flying over golf course, those things are everywhere now so watch out for them.
