Robinson said that Nguyen was an experienced mother, having given birth to male Bao in 2024.

In the same year, another baby Francois’ langur was born to mum Lulu at Whipsnade Zoo.

They live in matriarchal groups and engage in allomothering and allosuckling, where all of the female members lend a hand in caring for the infants.

This means their groups have really deep social bonds and it allows older siblings to learn important social skills.

Robinson continued: “Over time, the newborn’s hair will fade to black, so I’d definitely recommend coming to see him in his home at Monkey Forest whilst he’s still tangerine!”

ZSL, the conservation charity behind Whipsnade Zoo, works across the world to tackle the illegal wildlife trade, including in Thailand – considered to be the largest transport point for the illegal wildlife trade in Southeast Asia.
