What are the characteristics of orangutans?

Chimpanzees are semi-arboreal animals, and their ability to climb trees is much better than that of gorillas, but they are far less than gorillas, and they can't walk in the forest by their arms. Most of them land on all fours and are supported by curved knuckles. It is a stray animal with a certain range of activities, but its habitat is not fixed and it does not live in one place for a long time. It spends more time underground every day, foraging everywhere in the forest in the morning, staying in a place to play and rest in the afternoon, and starting to prepare for nesting. Branches with leaves will be interspersed with each other and spread on leafy trees 4-5 meters to 30 meters above the ground. At dusk, they slept in the tree until after sunrise the next morning. Chimpanzees are curious, restless, agile and intelligent. They often get together and make a scene during the day, which is very chaotic. They fight almost every 20 minutes, and often play games such as "swinging" and "hide and seek" with dense branches. The food is mainly fruits, fresh leaves and buds of plants, and bananas and melons from the countryside are also stolen. In the season when fruits are scarce, they also eat insects, birds and termites, and even round up large animals such as baboons, antelopes and wild boars in groups, jump on them and kill them, and then tear their prey into pieces and share them with the whole group. Using tools is a phenomenon in many animals, but chimpanzees can treat some tools to some extent before using them. Although this kind of processing is extremely simple and rough, it is an act of actively, purposefully and consciously transforming objects to make them more suitable for use. For example, it can not only poke an ant hole with its index finger, but also pick up a branch or a grass stick, squeeze and flatten the grass leaves with its palm, and put its hand into the hole to fish out the ants and eat them. If the straw is bent, bite off the elbow or change it. In addition, there are beating branches with long sticks, feeding on leaves and dipping sticks into honeycombs to eat. What's even more surprising is that sometimes it can chew leaves into sponges in its mouth, put them in tree holes that are difficult for its mouth to reach, and then take them out and put them in its mouth to absorb water. It will even find some herbs to treat gastrointestinal diseases. Chimpanzees eat a lot and spend 5-6 hours a day foraging, eating fruits, leaves, roots, flowers, seeds and bark, mainly bananas. Some individuals often eat insects, birds' eggs or catch young antelopes, baboons and monkeys, and the prey obtained by males is allowed to be enjoyed by group members. Chimpanzees have a very common eating habit. Interestingly, they get different foods in different ways. He is good at poking straw into termites' holes, pulling it out when termites are full, sipping it into their mouths, and placing and breaking fruits with two stone tools. Chimpanzees sometimes prey on some monkeys (such as red monkeys and black and white monkeys). Chimpanzees plan tactics when they hunt monkeys. Because chimpanzees can't catch the sensitive monkeys in the tree, one chimpanzee will catch up with the monkeys in the tree from the land first, while other chimpanzees will gather them from the tree and drive them to the ambush site. When land chimpanzees arrive at the ambush site, they will wait under the tree. At this time, other chimpanzees will block the monkey's way, leaving only an ambush channel.
