Orangutans are among the most intelligent primates.
Like we who read this.
Human activities have caused severe declines in the populations and ranges of both species.
The most recent estimates (2000-2004) for Sumatran orangutan Pongo abelii is around 7,300 and for Bornean orangutan Pongo pygmaeus is between 45,000 and 69,000. Today these are optimistic estimates.
The Sumatran species is critically endangered and the Bornean species is endangered.
Orangutans are losing their homes as tropical rain forests are being cut down for wood to make paper and furniture and the land is cleared to grow palm oil.
Baby orangutans are sometimes taken from their mothers to be sold as pets.
Orangutans are the most solitary of the great apes.
They spend nearly all their time in the trees and hardly ever come to the ground.
They construct elaborate sleeping nests each night from branches and foliage.
Orangutans may live up to 45 years or more.
The name “orangutan” is derived from the Malay and Indonesian words orang meaning “person” and hutan meaning “forest”, thus “person of the forest”.
Orangutans eat mostly fruit.
Orangutan hands are similar to human hands; they have four long fingers and an opposable thumb.
Orangutans use a variety of sophisticated tools.
The cage is not a home for orangutans.
