This is a very clever primate with a developed brain. In addition to having interesting life habits with many organizational features somewhat similar to human society, the yellow-cheeked black gibbon is also blessed with a light skeleton, flexible limbs and surprisingly dexterous flexible hands and feet. In them there are such interesting details as the difference in coat color between males and females, differences in coat color in the ages of the young. Males are black, on 2 cheeks there are two light yellow hairs. The top of the head has crest-like erect hairs. The limbs are long, without a tail. The female is yellow, the top of the head has a black feathered tip. With a little observance, visitors can even distinguish males or females through the deep, deep cry characteristic of this species. 
Unlike monkeys that live in packs and are often bold, apes are quite timid, always keeping a certain distance from humans. Primates such as gibbons and patchwork langurs take good care of their young. Each litter, the mother ape usually gives birth to one cub and has the habit of taking care of the offspring for about 3 years until the baby is mature enough. Early morning always seems to be the most active time for the ape family. They awaken visitors with melodious echoes to call family members and assert territories.
