Wrangel Island in the Russian arctic - the polar bears are waiting for winter. They have little to eat at this time of year and an old walrus skin makes a welcome distraction. The island and surrounding waters are a protected nature reserve and the polar bears can carry on their activities without disturbance.
At the end of September, the long wait is over. Tens of thousands of walrus migrate past the island and through the Bering Strait to escape the winter storms and sea ice. They travel long distances, but occasionally have to haul out onto land to rest. But as long as there are bears on the shore, the walrus will not dare to leave the safety of the water. Tackling a fully grown walrus on land is challenging enough for a polar bear. In water, it has little chance. The bear, never the less, keeps an eye on its potential prey.
A lone walrus has approached the far end of the beach. It’s weak and exhausted, resting its head on its long tusks. But it doesn’t go undetected for long. A large male has picked up its scent.
The next morning, little remains of the walrus. A young bear is attracted to the left overs. He approaches the carcass cautiously. The real owner could still be close by. But the large male is already far out in the tundra. Not many bears can tackle a fully grown walrus, but this colossal male will have had little trouble. He’s eaten his fill and can hardly move. The young bear takes full advantage of the owner’s absence. The big male is not likely to return to his kill. He won’t need another meal for days. But the younger bear takes no chances. He knows he could be disturbed at any moment. The walrus meat is a rich and fatty source of food and he is determined to make the most of this free meal.
