The silver-leaf langur babies at the San Diego Zoo are doing very well (see previous post, Langurs: Bright Orange Babies). Tevy’s baby, born on February 26, 2009, is almost all silver with only a little bit of orange left. Adamena’s baby, born on April 13, is still mostly orange. The babies play together throughout the day. I have seen them climbing around and jumping from one branch to the next. They will swing around on branches, holding on with one hand, and hang upside down.
We have not yet confirmed the babies’ genders, but we suspect they are females. We let the mother take care of the babies, and we do not interfere unless there are complications. They stay close to their mothers, which makes them difficult to sex. Once the babies start getting more confident, they will spend more time away from their mothers when they are close to us.
Tevy’s baby gets around very well and is a great climber. Adamena’s baby is learning fast. This mother is very protective of her baby; she doesn’t let her baby travel too far away. Tevy, on the other hand, is an experienced mother and is very laid back.
The babies like to play with Zoe, who is considered a subadult (not a juvenile but not quite an adult). Tevy’s baby especially is fond of Zoe; she will follow her around and grab onto her whenever she passes. Zoe tolerates the babies and for the most part seems to enjoy interacting with them. Come watch them on the Sun Bear Trial in the Zoo’s Asian Passage zone.
