Sumatra. These large apes swing from tree to tree by using their arms (brachiating).
Orangutan in Malay language means "human of the forest". The
Orangutan 's population is
decreasing and is in grave danger of extinction. The Expected
population is less then 40.000 in the world.
Early 2009 a rare subspecies of the orangutan is found in the area of
Kalimantan, this subspecies of Orangutan has black fur as a gorilla.
The Black Bornean Orangutan or
Pongo pygmaeus morio was
by scientists team of The Nature Conservancy in
the mountainous area of
East Borneo. While there is no exact number, and hard
to detect the total population, the scientist team has estimated the
Orangutan Population between 1000 to 2000 individuals. With this new
detect subspecies, there are currently three species of

Orangutans from Borneo and Sumatra and can be separate in
three subspecies, the Pongo pygmaeus pygmaeus and Pongo
pygmaeus morio From
Borneo, with a more round face and dark red and black fur, and the
abelii From Sumatra, with a bit narrow face and paler hair,

enough food. The female and male orang utan just stay
together during mating time for a few days. The Baby orangutan will
stay with it's mother untill about seven years of age. The
orangutans move every day and construct a new "nest" in the tree

AREAS TO SPOT ORANGUTANS
Kalimantan there are several National Parks where Orangutans can be
spot “easily”. Tanjung Putting National Park, at
here you can find them around Camp Leakey Rehabilitation Centre, Here
they are the most easily to spot, as they are common with humans,
feeding could be done. This is different with Kutai National Park at
East Kalimantan, where they live much more wild in their habitat, but
with some assistance of rangers and guides, mostly the Orangutan can be
seen. Tangiling Reserve at Central Kalimantan is
an other good spotting
place for Wild Orangutans, a bit north of Palangkaraya City, cruising
up the Kahayan River.
Sungai Wain Reserve at East Kalimantan is a new National Park with
about 200 wild Orangutans from the Wanariset Rehabilitation Center,
easily to reach from Balikpapan in less then a hour. The latest
developed Wehea reserve is a virgin jungle area where orangutans and
other wildlife species can be seen.
