Last year, a video from the forest showing the tragic events in a wolf’s lair went viral.

There, the wolf cubs attracted the attention of a brown bear, became easy prey, and even brought down the den.

The scenes were filmed on camera in the Nalibok forest, on the western bank of the Neman River, in northwestern Belarus. Most of the territory is covered with pine forests and swamps, and part of Naliboki is quite hilly.

We can follow the events when the bear comes to the den. To get to the cubs, he digs a larger hole, and then he has easy prey. Mom and dad soon returned to the den, but it was too late for the cubs.

The video has already become a real hit on the Internet – to date, it has been viewed more than 6 million times on YouTube alone. The proof of how cruel life is in the wild is beyond doubt.
