Celebes Crested Macaque
The Celebes Crested Macaque is an Old World monkey that lives in the northeast of the Indonesian island of Sulawesi (Celebes) as well as on smaller neighboring islands. The Celebes Crested Macaque is a diurnal rain forest dweller. This macaque is primarily terrestrial, spending more than 60% of its day on the ground foraging for food and socializing, while sleeping and searching for food in the trees.
It lives in groups of 5 to 25 animals. Smaller groups have only a single male, while larger groups have up to four males. The females, however, always outnumber the males by about 4:1. Since young males must leave their birth group upon maturity, they sometimes form bachelor groups before they look for a connection to an existing mixed group. Communication consists of various sounds and gestures; such as the presentation of the long eyeteeth while grimacing a clear threatening gesture.
The gestation time is 174 days, and the birth of the usually single offspring happens in the spring when food is more plentiful. Young animals are nursed approximately one year and become fully mature in 3 to 4 years, females somewhat sooner than males.

Young Celebes Crested Macaque
This is what makes the Monkeys so interesting for us: Their in many aspects amazing likeness to us human beings and at the same time the clearly visible differences.
Here the young Macaque surprises us by not using its hand for scraping - though it was already close to the ear, but putting it aside for reaching the ear with its foot.
