Orangutans have been observed using sticks to apparently measure the depth of water. It has been reported that orangutans use tools for a wide range of purposes including using leaves as protective gloves or napkins, using leafy branches to swat insects or gather water, and building sun or rain covers above the nests used for resting.

65% of the diet of orangutans consists of fruit. Orangutans primarily eat fruit, along with young leaves, bark, flowers, honey, insects, and vines. One of their preferred foods is the fruit of the durian tree, which tastes somewhat like sweet custard. Orangutans discard the skin, eat the flesh, and spit out the seeds. [citation needed]
Orangutans often interfere with these crops, however, to look for food to eat since they often cannot find food in the forest. [ 20 ] Over the past few decades, the rate of orangutan poaching has increased significantly due to the discovery of more efficient weapons and methods of killing, such as the use of poisons , AK-47s and explosives .

Orangutans are the most solitary of the great apes: social bonds occur primarily between mothers and their dependent offspring. Fruit is the most important component of an orangutan's diet, but they will also eat vegetation, bark, honey, insects and bird eggs. They can live over 30 years, both in the wild and in captivity.
Orangutans the outgroup: Investigations comparing humans and the three other hominid genera disclosed that the African apes (chimpanzees and gorillas) and humans are more closely related to each other than any of them are to the Asian orangutans (Pongo); that is, the orangutans, not humans, are the outgroup within the family Hominidae.
Bornean orangutan are more solitary than their Sumatran relatives. Two or three orangutans with overlapping territories may interact, but only for short periods of time. [23] Although orangutans are not territorial, adult males will display threatening behaviors upon meeting other males, and only socialize with females to mate. [24]
It will also eat bird eggs and small vertebrates. [8] Sumatran orangutans spend far less time feeding on the inner bark of trees. Wild Sumatran orangutans in the Suaq Balimbing swamp have been observed using tools. [9] An orangutan will break off a tree branch that is about a foot long, snap off the twigs and fray one end with its teeth. [10]
The Tapanuli orangutan (Pongo tapanuliensis) is a species of orangutan restricted to South Tapanuli in the island of Sumatra in Indonesia. [3] It is one of three known species of orangutan, alongside the Sumatran orangutan (P. abelii), found farther northwest on the island, and the Bornean orangutan (P. pygmaeus).
