A forest ranger photographed a brown bear and three cubs in Sanjiangyuan National Park o May 4.

The brown bear and three cubs seemed to be foraging for food after hibernation. The cubs followed their mother, who looked back frequently at her slow-moving babies.

Sanjiangyuan National Park is home to many endangered wildlife species. In recent years, through measures such as habitat protection, patrol, and monitoring, the wildlife population in the park has been increasing.
