Rare babirusa piglet 'the size of a grapefruit with legs' born at Chester Zoo; species faces extinction as swine fever spreads

A critically endangered babirusa piglet, named Rana and weighing between 300-500 grams, was born at Chester Zoo, offering hope for the species as African swine fever threatens their survival. Conservationists call her a "lifeline" as wild populations decline on four Indonesian islands.

CuriousCats Full Story

A critically endangered babirusa piglet named Rana was born at Chester Zoo, weighing between 300 and 500 grams and described as "the size of a grapefruit with legs." This birth is significant as babirusas, also known as "pig-deer," are facing extinction due to African swine fever that has devastated their populations on four Indonesian islands since it arrived five years ago.1249

Rana is the fifth piglet born to her mother, Matano, who was born at the zoo 11 years ago. Conservationists emphasize that piglets like Rana are a "lifeline for the species", as babirusas typically produce only one or two offspring at a time, making recovery slow when populations are threatened. Hannah Owens, a zookeeper, noted, "When she was born, she was tiny — about the size of a grapefruit, with legs. She's grown a lot and is doing really well."37

The International Union for Conservation of Nature (IUCN) is expected to upgrade the babirusa's status from vulnerable to critically endangered. Conservationist Amy Humphreys highlighted the ecological importance of babirusas, stating they help with forest regeneration by dropping seeds as they forage. The zoo is actively involved in breeding programs and has shared expertise with Indonesian partners to bolster babirusa populations.5

As the crisis escalates, conservationists are racing against time to protect this unique species, with Rana's birth symbolizing a glimmer of hope amidst the challenges they face.

Key Insight
“Rana is Matano's fifth piglet, and Matano now has descendants in zoos across Europe. The IUCN is expected to upgrade babirusas from 'Vulnerable' to 'Critically Endangered' after African swine fever hit their four Indonesian islands five years ago.”

“Hannah Owens and her team had good reason to keep a close eye on the calendar. After spotting Matano, a female babirusa at Chester Zoo, with a male named Bamm Bamm early this year, they began counting toward day 161. Almost every babirusa born at the zoo has arrived after precisely that many days. As the anticipated birth approached, the keepers moved Matano into a secluded space and gave her extra bedding. Then Rana arrived.”
