The Netherlands has developed a reconnaissance drone in the form of a large bird of prey

Guard From Above (Netherlands) once became famous for training birds of prey to fight enemy drones. An unusual continuation of this theme was the Evolution Eagle drone developed by its specialists, which resembles a real eagle in shape, size and movements.

Unlike some bird drones, it moves not by flapping its wings, but with the help of motors located in the front part of the wings. The flaps at the back of the wings and the tail are responsible for control.
All this, like a real eagle, at the same time does not prevent it from using upward currents in flight and even allows you to fly for some time with the engines turned off, saving battery power and not creating unnecessary noise.
