Hoolock Gibbons mate for life and the male and female vocalize long duets at the setting of the sun, to mark territory, to make other members aware of predators, or just vibin to the twilight. They might sing lullabies to their children too.
Eastern Hoolock listed as Endangered, Western Hoolock is listed Vulnerable by the IUCN.
