Bornean orangutan

Pongo pygmaeus

The Bornean orangutan, ''Pongo pygmaeus'', is a species of orangutan native to the island of Borneo. Together with the Sumatran orangutan, it belongs to the only genus of great apes native to Asia.

The Bornean orangutan has a life span of up to 35 years in the wild; in captivity it can live to be 60. A survey of wild orangutans found that males weigh on average 75 kilograms, ranging from 50–100 kilograms, and 1.2–1.4 metres long; females average 38.5 kilograms, ranging from 30–50 kilograms, and 1–1.2 metres long.

The Bornean orangutan has a distinctive body shape with very long arms that may reach up to two metres in length. They have a coarse, shaggy reddish coat and grasping hands and feet. They are highly sexually dimorphic, with adult males being distinguished by their large size, throat pouch and flanges on either side of the face, known as cheek pads.

The Bornean orangutan lives in tropical and subtropical moist broadleaf forests in the Bornean lowlands as well as mountainous areas 1,500 metres in elevation. It lives at different heights in the trees and moves large distances to find trees bearing fruit. It is found in the two Malaysian states of Sabah and Sarawak, and three of the four Indonesian Provinces of Kalimantan. Due to habitat destruction the species distribution is now highly patchy throughout the island, the species has become rare in the south-east of the island, as well as in the forests between the Rejang River in central Sarawak and the Padas River in western Sabah.
Wild Orangutan This is a wild orangutan from the Danum Valley in the heart of Sabah, in Malaysian Borneo. In just the past few decades, orangutans have lost most of their habitat throughout Southeast Asia due to conversion to oil palm plantation. Seeing this big male, complete with his well-developed cheek pads, was a rare treat. Bornean orangutan,Borneo,Danum Valley,Geotagged,Malaysia,Pongo pygmaeus,orangutan,rainforest


The Bornean orangutan is an endangered species, with deforestation, oil-palm plantations and killing posing a serious threat to its continued existence.

The Bornean orangutan is more common than the Sumatran, with about 54,500 individuals in the wild; there are only about 6,600 Sumatran orangutans left in the wild. Orangutans are becoming increasingly endangered due to habitat destruction and the bushmeat trade, and young orangutans are captured to be sold as pets, usually entailing the killing of their mothers.

The Bornean orangutan is endangered according to the IUCN Red List of mammals, and is listed on Appendix I of CITES. The total number of Bornean orangutans is estimated to be less than 14 percent of what it was in the recent past and this sharp decline has occurred mostly over the past few decades due to human activities and development. Species distribution is now highly patchy throughout Borneo: it is apparently absent or uncommon in the south-east of the island, as well as in the forests between the Rejang River in central Sarawak and the Padas River in western Sabah . There is a population of around 6,900 in Sabangau National Park, but this environment is at risk. According to an anthropologist at Harvard University, it is expected that in 10 to 20 years orangutans will be extinct in the wild if there is no serious effort to overcome the threats that they are facing.

This view is also supported by the United Nations Environment Programme, which stated in its 2007 report that due to illegal logging, fire and the extensive development of oil palm plantations, orangutans are endangered, and if the current trend continues, they will become extinct.

A November 2011 survey, based on interviews with 6,983 respondents in 687 villages across Kalimantan in 2008 to 2009, gave estimated orangutan killing rates of between 750 and 1800 in the year leading up to April 2008. These killing rates were higher than previously thought and confirm that, the continued existence of the orangutan in Kalimantan, is under serious threat. The survey did not quantify the additional threat to the species of habitat loss due to deforestation and expanding palm-oil plantations. The survey found that 73% of respondents knew that orangutans were protected by Indonesian law.

However the Indonesian government rarely prosecutes or punishes perpetrators. In a rare prosecution in November 2011, two men were arrested for killing at least 20 orangutans and a number of long-nosed proboscis monkeys. They were ordered to conduct the killings by the supervisor of a palm oil plantantion, to protect the crop, with a payment of $100 for a dead orangutan and $22 for a monkey.
A big ole male Orangutan close-up OK, I wanted to post a photo of a gorilla to celebrate my new status of "gorilla" but unfortunately I don't have any - I haven't been able to do the Gorilla tracking tour yet - so I chose the next best thing. This photo WAS taken in the wild even though it was made at a "feeding station" and I have expressed my misgivings about these in a forum post as well as on my earlier Orangutan picture. However, getting this close to a huge alpha male Orangutan in the wild is really only possible at a feeding station as they tend to spend their time very high in the forest canopy. An interesting note - you can tell that this is not a zoo animal by the presence of several scars (pale spotting) on his face. The males get these during their fights for dominance for the females in a territory. Although Orangutans are well-known for being the most peaceable of the great apes, the males occasionally do engage in hours long fights which can leave both contestants exhausted and bloody. Many old alpha males like this one carry the scars which are visible on their face for the rest of their lives. Bornean orangutan,Geotagged,Indonesia,Kalimantan,Pongo pygmaeus,Spring


The Bornean orangutan is more solitary than the Sumatran orangutan. Two or three orangutans that have overlapping territories may only interact for short periods of time. They are the largest arboreal mammal and spend almost all of their time in the trees, clambering between branches or using their body weight to bend and sway trees. Each night a nest is built from bent branches, high up in the trees.

The Bornean orangutan travels on the ground more than its Sumatran counterpart. It is theorized this may be in part because there is no need to avoid the large predators which only exist in Sumatra such as the Sumatran Tiger.

Males and females generally only come together to mate. Sub-adult males will try to mate with any female and will be successful around half the time. Dominant flanged males will call and advertise their position to receptive females, who prefer mating with flanged males.

The Bornean orangutan are among the slowest breeding of all mammal species, with an inter-birth interval of approximately eight years. They are long-lived and females tend to only give birth after they reach 15 years of age. Newborn orangutans nurse every three to four hours, and begin to take soft food from their mothers' lips by four months. During the first year of its life, the young clings to its mother's abdomen by entwining its fingers in and gripping her fur. Offspring are weaned at four years, and at around five years they start their adolescent stage. During this period they will actively seek other young orangutans to play with and travel with.

The Bornean orangutan diet is composed of over 400 types of food, including wild figs, durians, leaves, seeds, bird egg, and bark. It also eats insects but to a lesser extent than the Sumatran orangutan. Bornean orangutans have been sighted using spears to catch fish.
