The orangutans

Studies have shown that orangutans in the Ketambe area in Indonesia ate over 92 different kinds of fruit, 13 different kinds of leaves, 22 sorts of other vegetable material such as top-sprouts, and pseudo-bulbs of orchids.

They are extremely large animals weighing between 50 and 90 kilograms, roughly the weight of a fully grown human. The baby is taken care of by its mother for 8 years. Orangutan Behavior Social organization, male-male competition, life history, life in the trees, nest building, tool use, culture: Their beard starts to emerge while the hair around their face shortens and instead of pointing outwards it flattens along the skull.

Even after that, the young will still associate with their mothers.


There are three main reasons for this dietary behaviour: Infant orangutans will stay close to their mothers for up to three years. Orangutans build nests specialized for both day or night use. For example, studies show that Bornean orang-utans can fare well in logged forests if the impact is reduced through measures such as selective logging, keeping fruit trees intact, and controlling hunting.

In addition, orangutans may add additional features, such as "pillows", "blankets", "roofs" and "bunk-beds" to their nests. The majority of wild populations are located outside of protected areas, in forests that are exploited for timber production or are in the process of being converted to agriculture.

Most social bonds occur between adult females and their dependent and weaned offspring.

Sumatran orangutan

The study employed the techniques of psychologist David Premackwho used plastic tokens to teach linguistic skills to the chimpanzee, Sarah.

The Sumatran orangutan community is best described as loose, not showing social or spatial exclusivity. We also help to rescue orangutans from traders.

Engaging with timber companies to mitigate negative impacts on habitats and orang-utan populations. The population currently listed as P.

Inthe drainage of peat-swamp forest contributed to uncontrollable fires in Kalimantan, which lasted for 6 months and killed up to 8, orang-utans.

The Bornean orang-utan was once distributed throughout large areas of Kalimantan Indonesia and Sarawak and Sabah Malaysia on the island of Borneo. Lowland dipterocarp forests are preferred by orangutans because of their plentiful fruit.

The evidence suggested the differences were cultural: Road development, illegal timber harvesting and unsustainable logging, mining and human encroachment also contribute to habitat loss, degradation and fragmentation.

Knott further investigated tool use in different wild orangutan populations. They rest during midday then travel in the late afternoon. Occasionally soil from termite mounds were ingested in small quantities.Orang-utans are the world's largest tree-climbing mammals.

But their forest habitat in Indonesia and Malaysia is rapidly disappearing, putting the future of Asia's only great ape in peril.

Orang-utans have a characteristic ape-like shape, shaggy reddish fur and grasping hands and feet. Their.

Help us in our Mission to save orangutans and their habitat.

The mission of Orangutan Foundation International is to support the conservation, protection, and understanding of orangutans and their rainforest habitat while caring for ex-captive orphan orangutans as they make their way back to the forest.

The Sumatran orangutan (Pongo abelii) is one of the three species of orangutans. Found only in the north of the Indonesian island of Sumatra, it is rarer than the Bornean orangutan but more common than the recently identified Tapanuli orangutan, also of Sumatra. Orangutans are large apes that live in southeast Asia (on the islands of Borneo and Sumatra).

These apes mostly live in trees (they are arboreal) and swing from branch to branch using their arms. The word orangutan means "man of the forest" in the Malay language. As its habitats are being usurped by. Orangutans are the largest arboreal mammals and the most socially solitary of the great apes.

All three orangutan species — Bornean, Sumatran and the newly discovered Tapanuli — are critically endangered, primarily due to habitat loss. Orangutans have an enormous arm span.

A male may stretch his arms some 7 feet from fingertip to fingertip—a reach considerably longer than his standing height of about 5 feet.
