Rare Amur tigers video shows positive signs for population
Infrared video footage of Amur tigers in the wild in China has been captured in the Wangqing Nature Reserve.
The WWF footage is significant because the location of the cubs - 30 kilometres from the Russian border - means they must have been raised in China.
Wildlife experts have said this could show that the endangered species is making a comeback and that the Amur tiger population may even be restored one day.
John Barker, Head of India and China Programmes at WWF UK said the video is "pointing in every way that the tigers are actually breeding in China now".
