The recording comes as several people get killed and wounded in recent 'worst-ever' bear attacks.
Bears are increasingly coming out of the forest in search of food, say wildlife experts.
Vadim Klabukov, 23, paid with his life after flouting safety rules when he went to retrieve lost backpack in South Kamchatka nature reserve.
This animal and its lost mother wandered some 700 km too far south 'because they couldn't go north' and got confused.
Amazing footage shows the bears just 150 metres from the nearest house as shooting is criticised - but does little to deter predators.
Some 15 massive skulls disovered inside a cave in the Ural Mountains, where the bears went to die in late Pleistocene.
Video footage from Yakutia divides opinion: cruelty or necessary because predator was dangerous to people? Inquiry is underway.
