Northern White-cheeked Gibbon facts 🐒 south East Asian favorite 😻

#amazinganimals facts for kids The northern white-cheeked gibbon is a species of gibbon native to South East Asia. It is closely related to the southern white-cheeked gibbon, with which it was previously considered conspecific. The females of the two species are virtually indistinguishable in appearance. A "substantial" population of 455 critically endangered northern white-cheeked crested gibbons has been recently found living in the Pù Mát National Park in Nghệ An Province, northern Vietnam, near the border with Laos. Conservation International report they are living at high altitudes, and far from human settlements. This population, representing two-thirds of the total known in Vietnam are, apparently, the "only confirmed viable population" of this variety in the world. Northern white-cheeked gibbons are sexually dimorphic, with males and females having different colourations and the former also being slightly larger. Males have black hair over their entire bodies, except for distinct white patches on their cheeks, as well as a prominent tuft of hair on the crown of head, and a gular sac. Females are reddish-tan in colour, lack a cranial tuft, and have a crest of black or dark brown fur running from the crown to the nape of the neck. The northern white-cheeked gibbon is arboreal in habits, and primarily herbivorous, feeding mainly on fruits, with some leaves, buds, and flowers. However, up to 10% of their diet may be composed of insects and other small animals. They are generally sociable, living in groups of up to six individuals. Individual groups do not travel far, and are believed to be territorial. They are diurnal, and spend the night sleeping in high branches, often embracing one another tightly. The calls of northern white-cheeked gibbons are among the most complex of those produced by gibbons, and are significantly different between males and females. Northern white-cheeked gibbons are monogamous, with long-lasting pair bonds. The ovarian cycle has been reported to last an average of 22 days, and gestation lasts 200 to 212 days. At birth, both sexes are covered in yellow-buff fur, and weigh an average of 480 grams. Around one year of age, the fur in both sexes changes to a black colour, with pale cheek patches, with the sexually dimorphic adult coats only growing when they reach four or five years. During this period, the juveniles sing the female form of call, and regularly engage in play behaviour. Northern white-cheeked gibbons reach sexual maturity at seven or eight years, and have lived for at least 28 years in the wild. credits: https://commons.wikimedia.org/wiki/Fi...
