A tiny babirusa named Rana has been born at Chester Zoo — the first of its kind in several years. The newborn, about the size of a grapefruit, has already become a symbol of cautious optimism for a species found on only four Indonesian islands.
Babirusas, also known as "deer-pigs," differ from ordinary pigs: they typically give birth to one or two piglets at a time, rather than large litters. This makes the population especially vulnerable to sudden declines. Rana's mother, Matana, was herself born at the zoo eleven years ago and now has offspring in European zoos.
In the wild, the situation looks alarming. The species, previously considered vulnerable, will soon be reclassified as critically endangered due to African swine fever, which reached the islands about five years ago. Camera traps over the 2023–2024 years recorded only two encounters with the animals across all islands.
Zoos play a key role in preserving genetic diversity. Rana is the fifth in Matana's offspring, and her birth underscores the importance of captive breeding programs when wild populations are rapidly dwindling. Zoo staff monitored the mother and baby remotely using a baby monitor to avoid disturbing the sensitive animals.
Such events remind us that even small successes in controlled conditions can become a lifeline for the species as a whole. They show how closely conservation efforts are intertwined with threats arising far beyond zoo boundaries.
Rana's birth is a rare piece of good news that highlights the need to support breeding and monitoring programs while there is still time.
