Orangutans are daytime animals. They rise at dawn and search for food for a couple of hours. During the daytime heat, they rest in nests of branches that are arranged on trees, at an altitude of about four to 30 meters (by the way, they build a nest for 5-6 minutes), and when the heat subsides, they again go for food. In the evenings they again build a nest and settle in it for the night.
Unlike other anthropoid apes, orangutans live singly. Exceptions are females with cubs and adolescents who prefer to stick together. However, adult females, when they meet each other, behave peacefully. Another matter – mature males. They do not tolerate rivals, and if two males meet, especially in the presence of a female, the fight almost always begins.
