Orangs are solitary apes. Offspring stay with their mother till about six years old learning the ropes. The males need a range of about 1.2 square kilometres and the the female about 800 square metres. Our lodge happens to be in an 800 sq km range of one female and child. She put in an appearance just as we were starting the morning boardwalk walk with our guide. She made a day nest - they do this two or three times a day and then settle if it's to hot or too rainy.
After lunch naturalist Suhali gave an Orangutan Talk and got us learned up on one our closest genetic relatives. Apparently the appearance of the round face with big cheeks on males is hormonally triggered. If a a single male has his 1.2 sq km all to himself then he'll develop the cheeks. If a younger male challenges a cheeky male and wins, the winner gets cheeks and the loser deflates. In captivity, or near captivity, the orangs will pull their hair out. This was initially though to be an indicator of stress but it is now thought just to be smart. At places like Sepilock, at night the apes aren't experiencing the cool of the jungle. They were getting overheated living in or near the concrete buildings so, off with the hair. Also, sInce they are getting fed, their arm hair was not needed to troll for termites.
I caught the mother and child swinging away to there next stop later as I was sitting out on a viewing platform. Their strength is astounding!
The naturalist had kindly set up a telescope when the pair settled in a high tree in view of the lodge.
At four pm we headed out on an afternoon cruise to look for snakes. We found a couple curled up in a tree then suddenly it was monkey town and everyone forgot about the snakes except me as the boat had pulled in under the tree and the the snake was over me. Then the boat hit the tree while manoeuvring closer to the monkeys, then it hit it again making me very nervous. Oh, they're not poisonous says the driver waa-aay at the back. Really, they *look* like pit vipers says I...fortunately the current repositioned the boat and I was able to tell this tail.
A rope bridge was set up over this tributary of the Kinabatangan river and the troop of macaques availed themselves of the service. The rope was mainly for the Orangutans as they do not swim and this would increase their limited range through the reserve. No one has seen them use it yet but the macaques are opportunists.
Proboscis monkeys were settling in for the night...
A pair of rhinoceros hornbills - the biggest of several types of this unusual avian - flew overhead on our way back to dinner. Hornbills have horn shaped curves on their bills - inverted ones. It's a pretty distinct profile. When they nest they find a hollow in a tree or an abandoned woodpecker nest for the mother to burrow in before laying her eggs. After she is settled, she and her mate "mud" over the opening with poop, fruit and mud leaving a small opening for the male to pass food through. After the chicks are hatched and are big enough they all bust out. During the interment, the female cleans house and passes poop, etc. though the opening.
Just as we were approaching the lodge there was a troop of silver langurs with one adult albino - very rare!
Time to look for tarsiers in the dark....
