The bears definitely took notice of the drone. The animals’ heart rate skyrocketed when the UAV flew overhead, and their stress response was stronger when the quadcopter flew in windy conditions that masked the sound of its approach — apparently bears do not like being surprised. One bear started moving faster after the quadcopter flew by. And the bear that had experienced the greatest increase in heart rate — from 41 beats per minute to 162 — moved nearly 7 kilometers in the next 28 hours, encroaching into a neighboring female’s territory.
All in all, though, the bears weren’t stressed all that much, the researchers concluded.

At least there is this:
Ditmer’s team says that their results reinforce the NPS ban on drones in parks.




























i haven’t used it myself but https://jmp.chat/ looks good if you’re OK with a US or Canadian number.
