Orangutans on the island of Borneo are among the most endangered primates in the world and have become a symbol of the island’s wild nature. These remarkably intelligent animals spend most of their lives high in the forest canopy, where they build daily nests for sleeping. They are known for their strong arms and delicate motor skills, which allow them to move easily among the branches. Their diet consists mainly of fruit, leaves, and other gifts of the tropical rainforest. Females raise their young for many years, making orangutans some of the most devoted parents in the animal kingdom. Due to forest loss and illegal hunting, however, their numbers are rapidly declining. Across Borneo, various projects aim to protect orangutans and return them to safe areas. Encountering an orangutan in the wild is an unforgettable experience that often inspires a deeper respect for nature. These gentle giants remind us how important it is to protect the last remaining stretches of tropical rainforest.
The proboscis monkey, also known as the kahau nosed monkey, is one of the most distinctive primates of Borneo. It immediately attracts attention with its large, strikingly elongated nose, which is most prominent in adult males. These monkeys live mainly in mangrove and coastal forests, where they are excellent jumpers and swimmers – in fact, they are among the best swimmers of all primates. They feed on leaves, shoots, and fruit found in dense vegetation. Their population, however, is declining due to the loss of natural habitat, placing them among the endangered species.
