At birth, silvered leaf langur babies are bright orange.

Our silvered leaf langur troop has recently grown with the addition of two vibrant infants: Bakau, born on December 8, 2014 and Devi, born on March 10, 2015. They are easy to spot as langur babies are born bright orange! As they grow they will slowly change to the silvery gray color of the adults, a process that can take three to five months.

Langurs perform allomothering, where others in the group will frequently carry a baby, allowing the mother time to eat and rest. This behavior also lets younger females practice their parenting skills before raising their own infants. It is thought that the babies are born orange to attract attention and encourage group members to offer care. Our babies are so popular in the troop that even the males and all the youngsters want to carry them!

At over three months old, Bakau is already beginning to turn gray. His hands, feet, and head show a lot of gray hair and his orange coloring has become paler. The contrast is very apparent when compared to newborn Devi and his vibrant orange color. Bakau grows more independent every day and can often be seen climbing around on his own and wrestling with his siblings. Little Devi has yet to venture of off his mom, but it won’t be long before he joins in the fun.

The youngsters—and the whole troop—can be seen at the San Diego Zoo, in their special habitat located next to the orangutans and siamangs.
