In the video above, you can hear some of the most genuine and feral sound: Siberian tigers roaring in the wild.

The video clip and the natural soundtrack were collected on December 2, 2019, in the Siberian Tiger and Amur Leopard National Park, in northeast China.

At the end of the last century, Siberian tigers and Amur leopards almost disappeared in China, but as the environment improves and protection measures are taken, both species have returned. 

In recent years, the populations of Siberian tigers and Amur leopards in China have increased steadily. More promisingly, there are more female Siberian tigers settling down in the national park. Statistics prove that the "king of the forest" has returned, and the population of the species is expected to be larger in the near future.
