A rare scimitar-horned oryx, a species which is classified as extinct in the wild, has been born at Dublin Zoo.

The male calf, which was born on Wednesday 25 July, weighs around 25kg and brings the herd at the zoo to seven.

The scimitar-horned oryx was once widespread across northern Africa, but have gradually disappeared from the wild due to overhunting, habitat loss and competition with domestic livestock.

However, there has been no definitive evidence of their presence in the wild since the early 1990s and the species have been classified as extinct by the International Union for Conservation of Nature.

Dublin Zoo is home to a breeding group of scimitar-horned oryx and since 2013 has been involved in an international programme to re-introduce the species to parts of Tunisia.

There are now more than 200 zoo-bred oryx living in semi-wild areas in four national parks across Tunisia.

A Dublin Zoo spokesperson said the new arrival is "doing extremely well" and was up and running about an hour after being born.
