On December 13, Philadelphia Zoo welcomed a new female Francois Langur baby, born to Mei Mei and Chester. Her name is Quý Báu, pronounced "Qwee Bow", meaning “precious,” in Vietnamese. This is the first successful breeding of this species at the Zoo, and the first offspring for parents Mei Mei and Chester.

As a first-time mom, Mei Mei struggled in the beginning, but thanks to advanced planning, input from the Species Survival Plan (SSP) and great response and action from keepers and veterinarians, they were able to get mom and baby back together on day one, and reunited with the group just a few days later.

Ling, Mei Mei’s sister and exhibit mate, is doing a great job, helping mom out, carrying the infant throughout the day and returning to mom to feed, as is expected for this species. Native to Southern China and Northern Vietnam, François langurs are endangered in the wild.  Guests will be able to see this family in Zoo360 when the temperatures are 40-degrees or warmer, similar to the temperature in their native regions.
