A rare Somali wild ass has been born in a zoo in Chile, the fourth specimen of the critically endangered species to be born in the South American country, the zoo owner said.

The foal, named Julieta, was born in a private zoo on June 19, said Ignacio Idalsoaga, a veterinarian and founder of the zoo.

There are less than 200 left in the wild, and a similar number in captivity. Seven of the latter are in South America, all at the Buin Zoo in Santiago, according to the International Union for Conservation of Nature (IUCN).
