The western Borneo gibbon ( Hylobates abbotti ) is a primate species endemic to Borneo from the family of the gibbons (Hylobatidae).
distribution
She comes to the west of the island in a pie-shaped area in front, the north of the river Kapuas located in the center until the Müller mountain ranges and most of the Indonesian province of West Kalimantan , and the extreme west of the Malaysian state of Sarawak comprises.
features
The tailless Western Borneo gibbon reaches a weight of 5.5 to 6 kg (females) and 5.9 to 6.4 kg (males). It is colored medium gray. The top of the head and stomach are a little darker. Hands and feet are the same color as the rest of the body. The hair on the top of the head runs in a fan shape from the forehead to the back and is significantly longer above the ears.
Habitat and way of life
The monkey species lives in primary and secondary deciduous forests and tropical evergreen forests, often with high populations of wing fruit plants . It can also survive in selectively cleared forests, provided there are enough fruit-bearing trees left. Like most gibbons, Western Borneo gibbons feed on ripe fruits, young leaves, flowers, and insects. Detailed research on nutrition, social behavior and reproduction has not yet been carried out for this species.
Systematics
The western Borneo gibbon was first described as Hylobates cinereus abbotti by the English zoologist Cecil Boden Kloss in 1929 . For a long time it was considered a subspecies of the gray gibbon . According to recent morphological and genetic studies, however, it is an independent species. Its range overlaps at the edges with those of the three other gibbon species of Borneo. In central Borneo, the Western Borneo gibbon hybridizes with the white-bearded gibbon ( H. albibarbis ).
