Northern Yellow-cheeked Crested Gibbon Nomascus annamensis

Endangered

Location: Cambodia, Laos, Vietnam

The Northern Yellow-cheeked Crested Gibbon lives in broadleaf evergreen and semi-evergreen forests, at elevations of between 100-1,200 m asl. These gibbons are frugivorous but also consumes significant proportions of leaves, young shoots and flowers. They are also known to feed on Finlayson’s Squirrel (single record by an adult female) and lizards. Food sharing has been observed (Geissmann 1995, Duc et al. 2016).

Listed as Endangered based on a suspected population reduction of at least 50% over the past 45 years (three generations), primarily due to logging, agricultural encroachment, and hunting, and a suspected continuing decline over at least 15 years (one generation) into the future. In Cambodia’s Virachey National Park, large areas have been cleared for rubber plantations in recent years, particularly on its eastern side, and the area is also subjected to illegal logging for luxury timber.

These gibbons belong to genus Nomascus. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other and form monogamous breeding pairs. Males and females have different coloured fur.

Numerous conservation efforts of these rarest of small primates are ongoing. Sponsor a gibbon at a rescue centre here.
