#StlZooMonkeyMania continues! Our primate keepers selected eight monkey species to be featured in a friendly online voting competition, and you have helped narrow our species down to the Forest Four. The champion will be featured on our social media and have the Primate House named after them for the day!
Our first match-up in our Forest Four is between the Francois/spectacled langur and the Guereza colobus monkey.
Which do you feel has the best social/family dynamic?
Langur groups typically consist of one male and multiple females. The females share responsibility in caring for all the young, a behavior known as "allomothering" or "aunting" (but with less cheek pinching). In contrast to the black and gray coloration of the adults, the infants sport a bit of pizazz with bright orange fur. This allows the group to easily keep track of the infants as they are passed back and forth between females, like a strange game of hot potato.
Colobus moms do not have to look hard for a babysitter for their infants because of a special parenting behavior called “allomothering.” All of the females in a colobus family will take turns holding and carrying the infant when mom is busying eating or socializing with other members of the family.
