Weighing about 27 kilograms (59.52 lb), the yet-to-be-named female calf was born on Saturday at the Sumatran Rhino Sanctuary (SRS) facility in Way Kambas National Park, Lampung province in the tropical Southeast Asian country.

Covered in black hair, the newborn stood about 45 minutes after her birth. On the next day, she began to walk around the jungle, the environment ministry said in a statement.

The mother, 22-year-old Ratu, was in a healthy condition, the ministry said.

Ratu is a native of Lampung, while her mate, Andalas, aged 23, was born at the Cincinnati Zoo, United States, but has since moved to the same park as Ratu.

The pair previously had Delilah in 2016 and Andatu in 2021.

“This is a happy news, not only for Indonesia but for the world,” environment minister Siti Nurbaya said in the statement.

There were just 80 Sumatran rhinos left in the world, based on a 2019 assessment of threatened species by the Indonesian government.

The mammal, Dicerorhinus sumatrensis, is the only Asian rhino with two horns and can grow up to 1.5 metre-tall, weighing between 500 kg to 960 kg.
