Have you ever heard a drone take off? They can be loud enough to get your heart racing. A recent study suggests that wildlife could be equally bugged by the buzz of drones.

Scientists have used tracking collars to gather data about six bears while drones flew past on 17 different flights. Although the bears didn't run away, their heart rates spiked when they heard the drones, suggesting a stress response. Maybe it's time to rethink sending drones to wild spaces and give nature a bit of peace.

The bears studied live in areas with lots of human activity. Animals in more remote areas could be affected even more.
