Pongo pygmaeus the orangutan essay

The orangutan, Pongo pygmaeus, is an ape that may be found in the moist, seaside rainforests of Sumatra and Borneo which in turn consists of Indonesia’s Kalimantan pays, Malaysia’s Sabath and Sarawak, and the kingdom of Brunei Darussalam. Orangutans live in exotic rainforests and they are arboreal primates meaning that they are really tree home. Orangutans create nests inside the tree divisions for the night time in which they will curl up and sleep. These kinds of nests are made out of leaves and branches and they’ll sometimes make use of a leaf like a roof to shield themselves in the rain.

Orangutans happen to be omnivores, meaning they eat a variety of beef and plant life. They mainly eat fruit, leaves and small pets or animals. However , 70 percent of a crazy orangutan diet is fruits (Napier, 1988). The durian fruit is a juicy although smelly, cantaloupe-like substance that is among among the orangutan’s faves. They also consume flowers, bark, nuts and small pesky insects such as termites and butterflies larva (DeBoer, 1982).

Adult orangutans are primarily solitary, apart from mother-offspring pairs. However , weaned juveniles is going to sometimes group in little groups. Orangutans are lively during the day, or perhaps as (DeBoer, 1982) stated diurnal. They will live only in large territories. This is probably due to their diet plan, they need a sizable area to obtain enough food and a lot of orangutans in a single area may cause starvation.

The only lasting orangutan social group is a mother and offspring, who live jointly for about 7 years. When mating, the male and female orangutans stay together pertaining to only a few days. Males happen to be aggressive toward each other and sometimes fight more than females. Additionally they will risk out areas in which that they claim as their territory and fight various other males if possible (Galdikas, 1992). The dominance hierarchy may be the ranking program among the Primates. The structure among orangutans is the Noayu, which is where there is a solitary male. There may be marked sex dimorphism among the orangutans. Females weigh just half as much as the men. Being less heavy, females and juveniles typically stay in the trees. Not simply is there a apparent difference in dimensions, but guys also possess quite a few distinct characteristics than female orangutans do. For instance , males possess big cheek pads and facial hair that resembles a man’s moustache and beard.

The numbers or orangutans have got recently lowered tremendously owing to loss of home to deforestation and the eradicating of females for their fresh, to be marketed as pets or zoo animals. Less than 30, 000 individuals are considered to remain in the wild, and the species shows up as decreasing in numbers (Galdkias, 1987)

In relation to my observation, the orangutans acted very similar in captivity as though they were inside the wild. The area was limited, but for the actual had to work with, they shown many of the manners they would possess given these were in the wild. I noticed the males remained solitary, since proven inside my research. In one instance, Kiko approached his sister and in addition they groomed for a short amount of time, and Kiko entered a different portion of the housing and continued to be by himself until the end of my observation. Junior, the dominating guy, and dad of Kiko, also stayed at confined to him self. There was hardly any interaction between Junior as well as the other orangutans. At one point of the observation, Jr . showed an exhibit of anger, sort of proving his prominence and entered the corner to create a small, grounded nest. There was many displays shown through the entire thirty- small time frame. As stated above, Junior was upset because he was woken up by commotion with the visitors, and began to throw the plastic barrel or clip around. This might also relate with the sociable structure of a typical orangutan community. The men show aggression when their house feels threatened by an additional living factor and that could explain his irritation together with the crowd.

On several occasion, Bonnie, demonstrated a display of brachiating from department to department, and also up and down the door against the cup. Orangutans happen to be arboreal, meaning they are tree dwelling primates, so it is simply natural instinctly and actually for them to brachiate throughout a tree-
