Orangutans are one of the most expensive animals in this trade. Often, the poaching of orangutans is linked with the illegal pet trading, where it is highly common for poachers to kill adult females, and take the infant to sell on the black market. [21] According to a survey, hunters are paid approximately USD$80 to $200 for an infant orangutan ...
Orangutan researcher Birutė Galdikas presenting her book about the apes. Orangutans were known to the native people of Sumatra and Borneo for millennia. The apes are known as maias in Sarawak and mawas in other parts of Borneo and in Sumatra. [13] While some communities hunted them for food and decoration, others placed taboos on such practices.
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 orangutan will use the stick to dig in tree holes for termites. They will also use the stick to poke a bee's nest wall, move it around and catch the honey. In addition, orangutans use tools to eat fruit. [11]

The Bornean orangutan diet is composed of over 400 types of food, including wild figs, durians (Durio zibethinus and D. graveolens), [29] leaves, seeds, bird eggs, flowers, sap, vines, [30] honey, fungi, spider webs, [30] insects, and, to a lesser extent than the Sumatran orangutan, bark.
Bornean orangutans (Pongo pygmaeus) exhibited aggression in almost 90 percent of their copulations, including when the females were not resisting. [13] A possible explanation for aggressive behaviors in primates is that it is a way for males to train females to be afraid of them and be more likely to surrender to future sexual advances.
