At one part of the video, after a jump cut showing the cub climbing closer to the top, the drone appears to zoom very close to the cub. The mother bear, appearing to look at the drown, swipes toward the cub, causing the cub to slip all the way down the slope. The cub walks a few feet over and attempts to climb up the slope again.
The drone appears to keep a far distance from the pair this time, as the cub makes it to the top and the two bears run away.
Biologist and University of Maine professor Dr. Jacqulin Gill was critical of the video, saying on Twitter, "Harassing wildlife for a photograph, a selfie, or a video is never okay. Respect animals by giving them space, and don't share posts where animals are clearly in distress or in danger just because someone wanted to go viral.
“The video going around of a bear cub scrambling up a snowy cliff to get back to its distressed mother is being shared as a heartwarming metaphor for persistence. It’s not. It’s a dangerous stunt by an irresponsible drone operator who should know better.”
Gill also directed readers to a link that provides a guide for using drones when examining and studying wildlife. The guide, from Jarrod Hodgson and Lian Pin Koh of the University of Adelaide, mentions a small study of American black bears in which drones increased the heart rate of bears as much as 123 beats per minute.
