A Sumatran rhinoceros is pregnant with her second calf at an Indonesian sanctuary in the original habitat of the highly endangered species.

Ratu's first calf, a male born in 2012, was the first Sumatran rhino born in an Asian breeding facility in more than 140 years.

A government conservation official, Bambang Dahono Adji, said Wednesday that Ratu was expected to give birth next May at Way Kambas National Park in southern Sumatra.

The father is Andalas, who was born at a U.S. zoo and moved to Indonesia for mating in 2007.

Sumatran rhinos are seriously threatened by loss of habitat and poaching. Fewer than 200 live in Indonesia and Malaysia today.
