What wildlife will I see in Borneo?

These strange creatures are quite unique – they are the only great ape to live outside Africa, and the only one which does not live in a group. They are also uniquely adapted to their forest habitat, spending far more time in the trees than their African cousins – chimpanzees, bonobos and gorillas – building nests to sleep in and swinging through the treetops with their great, long arms. Orangutans are renowned for their intelligence; some groups have been discovered using tools, and they have been observed using leaves to make rain hats and as waterproof covers for their nests. Experiments in the 1960s also found they were able to learn basic sign language – putting them on an intellectual par with chimps.

Baby orangutans are much like baby humans; they spend seven or eight years by their mothers’ sides, learning to climb, swing, forage and build nests. Orphans who arrive at the rehabilitation centres are paired with adults through a buddy system, as their human carers cannot teach them all they need to know about being a wild orangutan! Orangutans eat fruit, bark, honey, leaves and insects – but one of their favourite treats is the foul-smelling durian fruit.

Found only in Borneo, proboscis monkeys are regularly lauded as one of the world’s ugliest creatures. The reason for the males’ pendulous noses is not fully understood, though it could help their honking calls resonate through the forests, or be used to seduce females. The males have the longest noses of all primates – 10cm is common, though older monkeys can have noses stretching up to 17cm.

This is one of the largest monkey species, and one of their most surprising characteristics is perhaps how human they are, as they lounge in the trees with their legs dangling from the branches.

Sadly, as a result of severe habitat loss, these amusing monkeys are now listed as endangered, although several are sheltered within Borneo’s orangutan sanctuaries. And luckily for them, the Ugly Animal Preservation Society is on their side.
