The Gorontalo macaque ( Macaca nigrescens ) is a primate species from the genus of macaques within the family of the vervet monkeys (Cercopithecidae). It is closely related to the crested monkey and is sometimes considered a subspecies thereof. The species is on the Indonesian island of Sulawesi (Celebes) endemic , more precisely in the province of Gorontalo to the northern peninsula.
features
Gorontalo macaques reach a head body length of about 60 (males) or 50 (females) centimeters, plus a tail 2 to 3 centimeters long. Like the closely related crested macaque , the Gorontalo macaque has a high head of hair on the top of the head, but with a height of 5 to 10 cm, it is shorter than that of the crested macaque (10-15 cm). Young animals are light brown, hair, arms, hands and feet are black. The fur of adult animals is dark red-brown to blackish, a black central stripe is on the rear back. The slightly bean-shaped, hairless seat calluses on the buttocks are dark brown to dark orange and not further subdivided. The hairless face has high cheek bars.
Way of life
The habitat of these animals are tropical lowland and mountain rainforests up to heights of 2000 meters. Like all macaques, they are diurnal and live both on the ground and in the trees. Gorontalo macaques live in groups made up of several males and females. The diet of these primates consists mainly of fruits (approx. 70 - 85%), as well as leaves, buds and insects. Sometimes they also invade plantations and consume the field crops (fruits, vegetables, corn).
Like many inhabitants of the Southeast Asian islands, the Gorontalo macaque is endangered by the ongoing destruction of its less than 20,000 km², fragmented habitat. The species lives relatively safely in the mountainous parts of the Bogani Nani Wartabone National Park that are difficult to access for humans .
