Early this morning we discovered that our female Francois Langur, Saigon, wasn't carrying her infant, Ganju. Unfortunately, while searching the exhibit, we found Ganju on the ground showing no signs of life. He was rushed to our Wildlife Hospital, however, our veterinarians confirmed the langur had died early today. The post mortem showed he was under weight and hadn't been getting enough milk from his mother, although she was doing all the right things in caring for the infant. All the Keepers on the Primate Unit are saddened by what has happened today, considering everything appeared to be going so well. We've been keeping a very close eye on Saigon and Hanoi and we'll continue to do so over the coming week. - Senior Primate Keeper, Tracey
