Endangered (IUCN) and federally endangered Francois’ langurs (Trachypithecus francoisi) at Omaha Henry Doorly Zoo. This species exhibits ‘aunting’ behavior, meaning several females will take care of the same baby. The bright orange coloration (which disappears by age six months) is thought to allow for easy tracking of the young one no matter which surrogate mom has it at any time.
