Indonesia's government says the rare Sumatran rhinoceros was born last week and stood up 45 minutes after her birth.

An endangered Sumatran rhinoceros, the smallest and hairiest of the five extant rhino species, was born in Indonesia last week in a conservation area, the country’s government said on Monday.

Weighing about 27 kilograms, 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 calf’s mother, 22-year-old Ratu, was in a healthy condition, the ministry said.
