A group of polar bears have taken over an abandoned research station off Russia's far eastern coast. The animals have been intimately captured in drone footage taken by Russian traveler and photographer Vadim Makhorov. Makhorov was on a sea cruise in the Chukchi Sea with a group of tourists, when he spotted the polar bears near an abandoned building while he was filming the landscapes of Kolyuchin Island. The animals were using the building as a shelter to live and rest. Originally published in
