In a heartening development for the critically endangered Sumatran rhinoceros species, a male calf was born on Saturday at the Sumatran Rhino Sanctuary in Way Kambas National Park, located on the western Indonesian island of Sumatra. The newborn calf, born to a mother named Delilah, is the second of the species to be born within the past two months, reinforcing efforts to conserve this dwindling population.

Delilah, who was born at the sanctuary in 2016, made history by becoming the first rhinoceros mother to be born and give birth at the sanctuary, marking a significant milestone for the breeding program. The birth of the yet unnamed male calf is a testament to years of hard work and international collaboration, offering hope for the survival of the species.

The birth came as a surprise to the sanctuary staff, as Delilah went into labor 10 days before her expected due date. Sanctuary workers discovered Delilah and her calf in the forest approximately four hours after birth. The calf, standing, walking, and breastfeeding, weighs around 55 pounds (25 kilograms). Both mother and baby are in good condition and are under close monitoring.

The male calf is the fifth rhino to be born at the sanctuary since 2012, as part of a government-backed initiative to protect and conserve the species. Delilah bred with a male rhino named Harapan, who was moved to the sanctuary from the Cincinnati Zoo in 2015. This successful breeding marks a significant achievement for Harapan, as previous attempts over eight years ended in failure.

The Sumatran rhinoceros population faces a critical threat of extinction, with fewer than 50 individuals currently living in the wild. The species is listed as critically endangered on the International Union for Conservation of Nature's Red List of Threatened Species. The International Rhino Foundation estimates that wild populations are decreasing, with as few as 30 adult rhinos remaining.

Sumatran rhinos, the smallest of the five rhinoceros species, are descended from the Ice Age's woolly rhinos and are known for their distinctive hairiness. With their two horns, prominent skin folds, and prehensile upper lip, they are agile runners and primarily feed on vegetation.

These recent births signify a glimmer of hope for the Sumatran rhino species, which is struggling to survive in their native Indonesian forests. The sanctuary's breeding program, along with international research and collaboration, offers the best chance of preserving and ultimately preventing the extinction of Sumatran rhinos.

As efforts continue to support the captive breeding program, conservationists remain devoted to protecting and saving these majestic creatures from disappearing forever.
