Orangutan in the Swamp

orang-utan of Borneo

Orangutan is a rainforest animal and it dislikes water, so I was surprised to see an orangutan foraging in swampy area of Kinabatangan last month. Actually this is not the first time it is found wandering in nypa forest, so I’m sure it wasn’t lost.

Nypa (or Nipah) palm swamp exists for over 70 millions years and it is one of the oldest forest types in the world. A large and well-preserved area of Nypa palm swamp grows around Abai, along the downriver of Kinabatangan River.

nipah swamp
Nypa forest is a swampy area with brackish water. Nobody wants to walk in Nypa forest, as its ground is muddy. Also, the number of mosquitoes there can suck your blood dry. Due to the semi-saline water and seasonal flood, very few plant and fruit species can flourish there. In short, Nypa swamp is a hostile environment to most animals. Egret, heron and wild boar go there sometimes, but they never call it home.

It was a quiet morning. I was on a birdwatching tour with friends in mangrove and nypa zones of Kinabatangan wetland. Our small boat entered a tributary of Kinabatangan River and cruised slowly in dense forest of Nypa palm. Instead of bird’s chirping, we heard loud noise of rustling leaves. We looked at the direction of the sound and saw the palm leaves shaked violently. There was something moving inside, and it was big.

The beast was moving slowly behind the Nypa palm along the river. We couldn’t see it, so we just followed the rustling leaves, hoping that it would show up near the river. After 10 minutes, our patience paid off and we saw it passed by a small opening between trees, for a few seconds. Affirmative, it’s an orangutan.

orangutan eating nypa palm
This orangutan stopped a few times to fall the palm trees. The palm is as big as my arm, and this orangutan could shake, bend then broke it easily. After crackling sounds of broken branch, there would be a long moment of silence, but we still could hear that it was munching something crunchy.

Our tour guide knew what it was eating. This orangutan was searching for the juicy core of the young Nypa palm. This is not the first time he sees orangutan in Nypa swamp, and he believes this is not the only orangutan active here. Behind the Nypa swamp is a forested land, probably where the orangutan lives. Most of the time this orangutan was staying quite far behind the trees. It was only one time I could peep through the tree gaps and photographed it.

The orangutan noticed us but not quite bothered about our presence. It just continued its food journey, almost breaking all the branches it grabbed. As mentioned, Nypa swamp is muddy and orangutan hates water, so it was climbing from tree to tree, to avoid getting wet in mud. Orangutan is smart. If it has to enter the water, it knows how to use stick to test the depth of water. Someone even saw orangutan eating fish. Probably orangutan knows how to fish too, LOL.

You can tell this orangutan is an adult by looking at its cheek pads called flanges. Unlike other primates, orangutan is a solitary animal and spends most of the time alone.

Below are more photos for your viewing pleasure. Such unusual scene and behavior are not something we see every day.

Normal tourists seldom visit this area so we have the cool view all for ourselves. 🙂

We saw other damaged Nypa palm next to the river and believed these are done by orangutan.

No doubt it was an interesting encounter. However, I’m very curious that why orangutan hunts for food in Nypa palm. Is it because orangutan can’t find enough food in rainforest nearby, or it loves the taste of Nypa palm? I wonder..

Someone read my article “Jackie, orangutan who owns a house” and asks, “does orangutan really live in house?” Definitely not! Orangutan spends its night by sleeping on the tree. As this great ape weight about 50 to 100 Kg, it needs something to support its body, so it builds a nest.

If you walk in Borneo rainforest, you would see huge nest high on the tree. It can be the “bed” of the orangutan. To estimate the number of orangutan population, researchers will count the number of orangutan nests. Other great apes such as gorilla and chimpanzee also build nest. In fact, orangutan is the largest arboreal animal in the world.

orangutan at Kinabatangan
Last month I was on a river cruise at Kinabatangan River nearby Abai Village around 5PM. Suddenly my tour guide exclaimed, “Look! That’s a orangutan!” It was so far away that it took me some effort to spot this adult orangutan on top of a tree at river bank.

I had seen semi-wild orangutan in Sepilok Orangutan Rehabilitation Centre and Lok Kawi Wildlife Park, but I only saw wild orangutan a few times.

Our boat approached the tree of this orangutan slowly and quietly for closer look. Then it started to climb. “Oh no! It must have seen us and want to flee..” I thought I would lose sight of it very soon.

Wait… It stopped on a big branch and started bending branches.

orangutan making nest
“It’s making a nest,” my guide said, “orangutan builds a new nest every evening for its bedtime.”

orangutan bending branch
Laran (species: Neolamarckia cadamba) is the favorite tree of orangutan for making sleeping nest, so the villagers start to plant more Laran near their places, to promote conservation and nature tourism.

Not every tourist is lucky to see this. I was so excited! It was my day.

orangutan making bed
Orangutan is a tree dweller. It spends most of its time on tree, from foraging, feeding to sleeping. To avoid predators such as Clouded Leopard and Sun Bear, orangutan seldom comes to the ground. That’s why forest is an important habitat for orangutan, and that’s why they become endangered species, after people cut most of the rainforest. Tree is a Home to orangutan.

orang-utan preparing for bedtime
It was folding bigger branches to form a nest scaffold for its bed, then bending down and weaving small branches to form dense leaf covers on top and bottom.

Its skill was so sophisticated that a tree bed was constructed within 15 minutes. At last it laid down and made itself comfortable.

bedtime of orangutan
According to a research by scientists at the University of Manchester, orangutans show engineering skills when building nests.

Such finding is based on a few observations:

  1. Orangutan chooses tree with good structural support for its nest. This is an intelligent decision rather than a random selection.
  2. It knows how to use strong branches as base and thinner branches for a springy mattress.
  3. To take advantage of the flexible branches for making of a tent-like nest, orangutan bends, but does not break the branches and twigs, to keep them attached around.

Again, orangutan impresses me… Good Night orangutan!
