An endangered species of zebra is the first of its kind to be born at Chester Zoo in more than 30 years.

The unnamed female Grevy's zebra was born on Saturday to first-time parents Nadine and Mac, the zoo said.

Grevy's is the largest zebra species, found in small and isolated populations in Ethiopia and Northern Kenya.

Curator of mammals Tim Rowlands said "she is a lively one", born with brown stripes that will eventually turn black.

He said: "The arrival of this foal is not only a really good achievement for us but good news for the species as a whole."

There are thought to be fewer than 2,500 Grevy's left in the wild.
