The pandas are usually found in Nepal and China

The three-month-old pandas, Tenzing and Babu, were born at the Zoo as part of a conservation project to increase numbers and protect their long-term future.

They were named after famous Himalayan Sherpas, and have been in isolation with their mother since they were born.

The cubs were born with deep grey fur, which moults to reveal the red panda colouring.

Red pandas are endangered in the wild as much of their habitat and bamboo food supply is being destroyed.

They have suffered population decreases of around 40% in China over the last 50 years.

The forests in which they naturally live are being cleared, and the pandas are killed by dogs and hunted by poachers for the fur trade.

Lang Tang, the mother, who is eight years old, has stayed in the nest box with her cubs almost constantly since they were born, only coming out to collect food for herself.
