The gibbons reliably produced individual hoo calls for different contexts, including foraging, predator detection, encountering neighbours, and as part of duet songs by mated pairs. Researchers found the gibbons produced individual calls for different contexts like foraging and mating, and that subtle variations in these calls might be used to distinguish between different types of predator. Are gibbon s predator and prey? It shares the tree tops with orangutans, which, like the gibbon, rarely come out of the trees due to predators, such as tigers and possibly sun bears..

Females carrying infants may be more vulnerable to predators than other individuals because of their reduced speed and agility whilst moving through the canopy. The chief characteristics distinguishing apes from monkeys are the absence of a tail, their more or less upright posture and the high development of their brain.
