First-time parents Tundra and Ussuri and the team at Dublin Zoo are celebrating the birth of their two Amur tiger cubs.

The female cubs were born on October 14, weighing 1.5kg each, and can be seen by visitors to the Zoo this weekend from 11:15am to 3:00pm Saturday and Sunday.

Team Leader Ciarán McMahon said the Zoo's newest residents "are doing extremely well".

"Tundra is an exceptional first-time mother and she has shown strong maternal instincts from the very beginning," he continued.

"Both cubs are very playful and energetic, just like their mother! The cubs have fun chasing each other and play-fighting which helps keep their claws sharp, while Tundra makes sure to clean them up straight afterwards, just like any good parent would."

Amur tigers, formerly known as Siberian tigers, are an endangered species whose name was changed to reflect the fact that they are now only found in Russia's Amur Valley. With approximately 500 Amur tigers living in the wild, Dublin Zoo hopes its new arrivals will become part of an international breeding programme.
