Northern White-cheeked Crested Gibbon

The northern white-cheeked gibbon is a tailless ape with exceptionally long arms adapted for swinging beneath branches. Adult males are black with conspicuous white cheek patches, while adult females are buff or golden and retain a dark crown patch. Infants are born pale, males later become black, and females return to a lighter coat as they mature. Reported head-and-body length is 47–52.5cm, with males averaging approximately 6.4kg and females 6.6kg. (Animal Diversity Web; Mammalian Species)

This gibbon lives in family groups and travels through evergreen forest canopies, where fruit pulp forms the main food. Leaves, shoots, flowers and insects supplement the diet, especially as fruit availability changes with rainfall. Family members forage together and advertise their presence with loud, coordinated songs. Females normally produce one infant following a gestation of about seven months, with births separated by two or three years. Current species accounts place it principally in Laos and Vietnam; Chinese records are historical. (Animal Diversity Web; Mammalian Species)
