According to the Patriot-News, the attraction revealed Friday on social media that a baby François’ langur, or leaf monkey, was born to parents Mei Mei and Chester on Dec. 13. The infant, a female, is Mei Mei’s first, the zoo said.

The post also included a video of the baby, whose name is Quý Báu – Vietnamese for “precious.”

“When [the baby] was first born, our team noticed Mei Mei wasn’t attending to her, which isn’t uncommon for first-time moms,” the zoo wrote in a Facebook post. “So our vet staff took the baby to the animal hospital for a warming bath and some food.

“François’ langurs are native to Southern China and Northern Vietnam and are classified as endangered by the [International Union for Conservation of Nature],” the post read.
