The chip is connected to the brain with hair-thin electrodes implanted in key brain locations. Scientists then use a computer to order the bird to fly right or left and up or down.
The research is "military and intelligence" related, paralleling similar work by scientists with "Swiss Army homing pigeons" and sharks by the US Navy.
The Chinese scientists have successfully implanted similar electrodes in rats, mice and monkeys. No worries; they're still on the menu.
