Let’s learn about orangutans
The word orangutan means “person of the forest” — a good name for a group of primates that spend most of their time in trees. These great apes have long arms and long, curling fingers and toes for grasping branches. This helps them move easily through forest treetops on the Southeast Asian islands of Sumatra and Borneo.
Orangutans are more solitary than other great apes, such as chimpanzees and bonobos (and humans!). Adult male orangutans mostly live alone. But mama orangutans and their babies have a tight bond. Young orangutans tend to stay with their mothers for around seven years. And they’re even known to nurse for that long. While growing up in their mother’s care, young orangutans learn to build nests, sometimes starting as young as a few months old.

Nest-building isn’t the only example of orangutan smarts. These primates have been known to use tools for crushing nuts or insects to eat. And an orangutan was the first wild animal ever reported using a plant with healing properties to treat a wound.
There are three known species of orangutans: Sumatran, Bornean and Tapanuli. All three are critically endangered. Tapanuli orangutans, only discovered in 2017, are the most endangered of all great apes. No more than 800 of them are alive today. The greatest threats to orangutans are forest clearing and hunting — which means it is largely up to people to ensure these clever primates don’t go extinct.
