Physical Features

The Bornean orangutan has a dark red coat on his body with a round face to match, it has a clown-like look because of the semi-circular thick flaps of skin protruding from the two sides of his face; known as face pads, their eyes sink deep into their faces and the males grow beards which are pale brown in colour while the Sumatran orangutans are covered in long pale brown coats, they have no flaps of skin on their faces, they have long faces and the males also grow pale brown beards.

Breeding

The Bornean orangutans and the Sumatran orangutans have the same breading behaviors and terms(breeding period); the reproduction of these orangutans occurs only between two fully sexually grown(mature) orangutans, the males mate with more than one females and this characteristic is known as polygyny.

  • The female orangutans have a menstrual cycle lasting 22 – 32 days and minor bleeding for a few days after that; depending on the specie of orangutan.
  • They are not known to have menopause.
  • A female orangutan can have up to four offsprings before death.

Cross-breeding of Sumatran orangutan vs Bornean orangutan

The Sumatran orangutans and the Bornean orangutans can be cross-bred and the hybrids produced in the process are known as cock-tail orangutans or simply are called mutts.

Habitat

The Sumatran orangutans are known to spend most part of their entire lifetime as arboreals; living high up trees in the rainforests of Sumatran while the Bornean orangutans are found in the primary lowland swamps and primary rainforests in Bornean.

Scientific Names

The scientific name of the Sumatran orangutan is Pongo abeliiĀ  while the scientific name for the Bornean orangutan isĀ Pongo pygmaeus.

Size

The average male Bornean orangutans have a size of 0.97 meters which equals 3.2 feet; the females have a size of 0.78 meters which is the same as 2.6 feet while an average male Sumatran orangutan has a size of 1.37 meters which is the same as 4.5 feet; the average size of females 3.58 feet which is same as 1.09 meters.

Weight( Sumatran Orangutan vs Bornean Orangutan)

An average male Sumatran orangutan has a weight of 70 – 90 kilograms which is the same as 155 – 200 lbs, the females weigh about 90 – 110 lbs which equals 40 – 50 kilograms while an average male Bornean orangutan has a weight of 90 kilograms which is same 198 lbs, an average female weighs 50 kg 110 lbs.

However, when any of these species are kept in detention, they grow up to weigh far more than those in the wild; some of them in the zoos weigh as twice as their counterparts in the jungle. This is purely happening due to the fact and that their movements(jumping, walking, and roaming) are restricted as these activities burn up fats in their body system.

Also, they do not face food shortage, whether for short period or for long periods of time; which is quite different from the situations or conditions which their counterparts face in the forests(jungle).

Diet

The Sumatran orangutans compared to their relations; the Bornean orangutans are more insectivorous and frugivorous; fruits like figs and jack fruits often serve as meals for them on a daily basis, they are known omnivores as they also feed on items like eggs; laid by birds, also they feed on small vertebrates and invertebrates and hardly feed on the inner back of plants.

While the diet of the Bornean orangutan is very diverse; as they are known to consume well over 400 different types of food; which includes plant leaves and seeds, especially figs and durians, they are also omnivores as they too eat insects and bird eggs, they also eat the inner bark of trees but they do this very rarely compared to the Sumatran orangutans.

Population

The Sumatran orangutan has a population of about 5000 living individuals left in the wild while the Bornean orangutans have a population of about 25,000 living individuals left in the wild; both of them have witnessed a percentage decrease of over 900 percent each in the past hundred years.
