The footage, taken by an aerial drone in the Magadan Region of eastern Russia, begins by showing a mother bear and her cub scrambling to reach the top of a steep, snowy incline. The climb is a difficult one for both, but even more so for the cub. He is seen sliding down after his first attempt at the ascent.
It's unclear at first if the bears are in a panic to escape the drone buzzing in front of them and racing in for a close-up — but as the cub finally nears the top, his mother suddenly takes an aggressive stance against the airborne intruder.
And that causes the little cub to slip yet again, this time even farther down.
