Why Are Some Monkeys Orange in Appearance? Science Can Help Explain Why This Happens

The species practices 'alloparenting,' which means every family members participates in raising the infant.

00:00We are at the Langer Glass House in Sun Bear Forest down Central Street.

00:13We just saw an infant Francois Langer that was born last week to a first-time mom.

00:18The baby is doing fantastic. We're all really excited, really impressed.

00:32The baby has gotten a lot stronger within just the last week.

00:36It's starting to look around and be very curious about its environment, which is exciting.

00:42So, this species practices alloparenting, which is where every family member participates in raising the infant.

00:54So, the infant is passed around to all the family members, and you're never quite sure which one is going to have them at the moment,

01:00but they all take great care of the baby.

01:12So, the infant is born orange, and the adults are black.

01:28So, the thinking goes that being orange, everybody wants to hold and investigate the infant,

01:33which will increase the odds that the infant will survive and be taken care of by the family.

01:39The Francois Langers are endangered. They are being hunted in the wild, and there's only a few thousand left.

01:52And in North America, there's a little under a hundred within the zoos here, so every birth counts.

01:58The great thing about the Francois Langers is they are fairly active throughout the day,

02:08and they'll either be sleeping in the sun or they'll be foraging, but either way, they're fun to watch.
