Amazingly like us.

1. Baby orangutans cry when they’re hungry, whimper when they’re hurt and smile at their mothers.

2. In their true habitat, male orangutans live alone and females live alone or with their infants.

3. An orangutan arms can have a reach of more than 8 feet! How tall are you? Probably not 8 feet or higher. So, an orangutan can have a reach of a length longer than you are tall!

4. Legend says that orangutans can speak but choose not to because they fear they would be forced to work if were they ever caught talking.

5. Most orangutans build a nest every night high up in a tree and sometimes even add a roof of leaves. architecture huh?

6. When it rains or the sun is hot an orangutan will hold a leafy branch or two over its head to protect itself from getting wet or overheated.

7. Mosquitoes bother orangutans just like they do humans and they will use branches like fly swatters to swish them away.

8. They will poke twigs into holes to catch insects, chew up leaves and use them as sponges and use branches and sticks to test the depth of water before entering it.

9. Generally, males are not successful in attracting sexually receptive females until they get their cheek pads. Thus, as sub-adults, the males frequently resort to "forceful copulation."

10. The female orangutan’s menstrual cycle is 29 to 32 days, with menstruation lasting three to four days.

11. While females stay near their mothers’ home ranges, males emigrate long distances. This helps minimize inbreeding within populations.

12. orangutans have been observed making simple tools to scratch themselves.

13. The male orangutan’s call plays an important role in repelling male rivals and advertising his availability to sexually receptive females, helping him to compete aggressively with other adult males. Thus, mature male orangutans appear to be intolerant of each other, and the meeting of two mature males usually results in either aggression or avoidance.

15. According to research, many practices by Orang-utans are learned from other group members and passed down through the generations.

16. In parts of Borneo, for example, orangutans use handfuls of leaves as napkins, wiping leftover food from their chins.

17. Orangutans in parts of Sumatra, conversely, use leaves as gloves, helping them handle spiny fruits and branches, or as seat cushions in spiny trees.
