Sumatran Rhino Sanctuary


It’s a boy! The Government of Indonesia has announced that first-time Sumatran rhino mom, Delilah, gave birth to a healthy male calf on November 25, 2023 at the Sumatran Rhino Sanctuary in Way Kambas National Park! In 2016, Delilah became the second calf ever to be born at the SRS. Now, she is also the first captive-born Sumatran rhino to give birth, a significant milestone for the breeding program. Delilah and her little boy, Indra, are both doing well.


There are ten rhinos being cared for at the Sumatran Rhino Sanctuary in Way Kambas National Park.

Born on May 12, 2016, Delilah was the second rhino birth at the SRS and the second offspring to Ratu and Andalas. On November 25, 2023, Delilah made history again when she gave birth to a healthy male calf. Delilah is now the SRS’s third breeding female and the first captive-born Sumatran rhino female to produce offspring. Veterinarians and keepers will monitor Delilah and her calf closely as they both learn about their new worlds.

At an estimated 42 years old, Bina is the oldest captive Sumatran rhino on record. Bina is also one of the original SRS residents, arriving in 1998 after being rescued from a logging concession in an area of southern Sumatra called Bina Samakta.

Ratu – whose name means “queen” – was born in Way Kambas National Park more than 20 years ago and was brought to the SRS in 2005 for her safety after wandering into a local village one night and being chased even farther from home. Ratu has had three calves: Andatu in 2012, Delilah in 2016, and a female calf on September 30, 2023.

As a young, wild rhino living in Bukit Barisan Selatan National Park, Rosa developed a dangerous habit of frequenting nearby villages for food, so was brought to the SRS where she could be better protected. After 8 miscarriages, Rosa became a mom for the first time when she gave birth to Sedah Mirah on March 24, 2022.

When Andalas was born at the Cincinnati Zoo in 2001, he became the first Sumatran rhino born in captivity in more than 112 years. He moved to the SRS in 2007 to join the conservation breeding program and has since sired two calves, Andatu & Delilah.

Harapan is Andalas’s younger brother and was also born at the Cincinnati Zoo. After living at several facilities throughout the United States, ‘Harry’ moved to the SRS in 2015 to join the breeding program. Harapan was the last Sumatran rhino to live in the US.

When Andatu was born on June 23, 2012, he not only was the first Sumatran rhino born at the SRS, but the first ever born in captivity in Indonesia. Andatu has made history again by becoming the second Sumatran rhino in the breeding program to sire a calf (who was born March 24, 2022).

Sumatran Rhinos are Critically Endangered

Despite continuous protection, the Sumatran rhino population has decreased by more than 70% over the last 30 years. Given the species’ Critically Endangered status, it’s important that we learn as much as possible about the Sumatran rhino – its basic biology, disease risks, food and habitat requirements – to help it survive. The rhinos living at the Sumatran Rhino Sanctuary serve as ambassadors for their wild counterparts, and as instruments for education for local communities and the general public. They also comprise an ‘insurance’ population that can be used to re-establish or revitalize wild populations, once threats have been eliminated in their natural habitat.


Sumatran rhinos need your help to survive. Make a donation to the International Rhino Foundation in support of the Sumatran Rhino Sanctuary today. Your donation will provide veterinary and husbandry equipment to care for the rhinos including medications and staff salaries, food and water for the rhinos and materials to renovate and expand the sanctuary when necessary. 

If we don’t act now, the Sumatran rhino could be extinct in our lifetime.

About the Sumatran Rhino Sanctuary

In 1996, the International Rhino Foundation (IRF) built the 250-acre Sumatran Rhino Sanctuary in partnership with local NGO Yayasan Badak Indonesia (YABI), who currently manages the SRS, the Indonesian Ministry of Environment and Forestry, Way Kambas National Park and Taman Safari International. Located in the heart of Way Kambas National Park on the island of Sumatra, the SRS is home to the only reproductively viable captive Sumatran rhinos in the world. The facility’s ten resident rhinos reside in large, natural rainforest habitats and receive state-of-the-art veterinary care and nutrition. This tiny population is the core of an intensively managed breeding and research program that is intended to promote the species’ population growth while also generating a genetically diverse “founder” group that could be used as a source for animals to repopulate the National Parks. The goal of this program is to increase our knowledge about the ecology and behavior of the species while also supporting the population in the wild. With no more than 80 Sumatran rhinos left in the wild, the Sumatran Rhino Sanctuary plays a critical role in the survival of the species.

In October 2019, IRF and YABI cut the ribbon on the expansion of the Way Kambas Sumatran Rhino Sanctuary in Indonesia. The larger sanctuary will provide a home for more rescued rhinos and support the Indonesian government’s national breeding program to help save the species. The SRS expansion is the third step in the emergency action plan developed under the guidance of the Indonesian government.

The Sumatran Rhino Sanctuary has produced the only five calves born in captivity in Indonesia. Female Ratu gave birth to a male calf, Andatu on June 23, 2012, after having been bred by Andalas in March 2011 and taking a 16-month pregnancy to term. Delilah was the second calf born to the pair on May 12, 2016. After eight lost pregnancies, Sumatran rhino Rosa gave birth to her first calf, sired by Andatu, on March 24, 2022. On September 30, 2023, Ratu and Andalas welcomed their third calf, another female. And in a historic moment, Delilah became a mom for the first time on November 25, 2023. Each of these births were the result of years of hard work and international research and collaboration – and they represent our best hope of saving Sumatran rhinos from extinction.
