Orangutan Communication
Orangutans are the least vocal of the great apes, however they will make long vocal calls to one another to attract mates. The reason they aren't that vocal is because they are solitary creatures most of the time so they dont need to communicate with one another that often or use vocal sounds to warn other Orangutans about predators.They have been known to make a variety of grunts, squeaks, moans, and barks however. Orangutans have been known to actually laugh like a human. Apparently they enjoy being tickled and will laugh just like humans would if they were being tickled.
In a lab or zoo setting some Orangutans have been taught sign language, but one of the most interesting things recently is the Miami Zoo is actually using ipads to communicate with their Orangutans! Apparently only the younger orangutans at this zoo are only interested in the technology, the older ones have no interest in it (quite like humans sometimes!). They play games on it, draw, and learn vocabulary with it. The program was initially created for humans with autism and the screen displays pictures of various objects. Unfortunately the tablet is too small for Orangutan hands so the trainer has to hold the tablet, and they are quite fragile (as we all know apple products are!) so they are working on getting a larger one for the Orangutans with a more "orangutan-proof" cover.
How cool is technology!?

Are you smarter than an Orangutan?
As I posted a video before of an Orangutan displaying human like skills. This post is going to go into the idea that Orangutans can really show imitation of humans and learning of skills from them quite well.
They have been seen copying some of the actions of humans by: sawing wood, hammering nails, combing hair, putting insect repellent on themselves, and trying to siphon liquid with a hose. Orangutans have also been seen trying to copy more complex human behavior, like trying to tie up a hammock between two trees, and even trying to start a fire!
Orangutans also possess insight on top of these actions. Meaning that with some learning they started to figure out what the desired result was ( A learned behavior). Orangutans also possess "self-awareness". Meaning they pass the mirror test of recognizing themselves in the mirror. This self-awareness is seen as a level of intelligence with primates. In fact some people regard Orangutans to be the smartest of all the apes!
As mentioned in a previous pose Orangutans are also frequent users and creators of tools to get what they want.
What do you think?!? Think Orangutans are pretty smart?!

Calm Creatures
Orangutans are pretty docile creatures. They are normally solitary creatures however the females will sometimes be social with other females as well as their own offspring. Males however are very solitary and they will show aggressive behavior to other males. When males square off they will make a lot of vocal noises sometimes physical combat can occur, females are not violent at all. Males will usually try and avoid all other males and females because they like to remain solitary. The only time they interact with others is when they are looking for females to reproduce with and somehow they encounter other males who are doing the same thing, which usually leads to fights.
They dont usually show predatory behavior to other animals because they mostly eat plants however they have been known to hunt and eat slow lorises. There also is not a lot of information regarding how they interact with other species of animals, my guess is that since they are pretty calm creatures they dont have huge issues with other animals, besides humans of course.

This is my territory
Orangutans are not very territorial creatures. Orangutans are usually solitary creatures, or at least living in small groups. Males and females have their own home ranges which usually overlap, however males try and avoid overlapping home ranges with other males. Males have larger home ranges than the females, however females home ranges tend to be more stable and permanent than male ranges. Males have been know to travel to other home ranges and be aggressive towards the male that lives in that range (everyone always wants something better!). Females tend to stay and create a home range that is close to the one they grew up in, where as males will travel as far as they please to find a home range, either way the males want the range where they can access the most females. Remember since females are sexually unavailable for a number of years due to their reproduction and raising of the child the male is usually forced to move ranges to find more fertile females.

Save the Orangutans
These adorable apes are actually endangered in their home of Asia. They are endangered in Borneo putting their numbers at about 54,000. Unfortunately they are critically endangered in Sumatra putting their numbers at 6,500. Things like farming, logging, and burning of forests have destroyed about 80% of their home in the rainforest. Another issues is the Palm Oil plantations that are popping up and also destroying the rain forest. It was shown that about 800 orangutans are being lost a year due to habitat destruction. Also poaching is an issue with poachers kill the mothers and take the young orangutans and sell them into the illegal pet trade.
Although orangutans have been shown to be very flexible in their habitat and dietary needs their numbers are still declining. Part of that issue is the fact that their reproductive cycles take such a long time. In a previous post it was mentioned that gestation periods last about 9 months and that mother orangutans take care of their young till they are about 7 years old. This causes any repopulation to take a lot longer than it would with any other animal.
However there are many organizations that are taking the initiative to help the orangutans. For instance our own San Diego Zoo works in conservation efforts with the Orangutans. There area also many websites to be found of groups that have opened Orangutan Sanctuaries as well as groups that are trying to actively protect the Orangutan's habitat. There are many things we can do like just donating money to help the cause or even adopting your own orangutan (not literally of course), and of course just raising awareness even helps the cause.

Orangutans at the San Diego Zoo!
If you haven't gotten a chance to see the Orangutans at the San Diego Zoo be sure to check them out next time you are there. I myself love going to watch these guys because they are usually right next to the observation glass so you can get a really good view of these animals. They can also be very entertaining! I watched them during feeding time once and its quite interesting to see them feed. Its clear they have favorite foods just like us. For example they seemed to ignore the lettuce being thrown at them but went directly for the fruit.
Their exhibit is quite interesting with lots of ropes to swing on and their are toys as well for them to play with. Below is a picture of the exhibit. On the right side of the picture you can see a rock like structure. This plays as a fake termite mound that the Orangutans can interact with. The keepers put barbeque sauce or ketchup or honey in the holes of the mound and the Orangutans have to get it out some way to get the treat.

Lets Get it On
Orangutan Reproduction:
Orangutans reproduce very slowly so there is a lot of competition between males to find females. Females are attracted to flanged males. There are two types of males in the Orangutan populations, flanged and unflanged. Flanged males are the larger of the two with cheek pads, throat pouches and longer hair. On the other hand females are still very selective in their mating process and will turn away any male that doesnt fit her fancy. Unfortunately this has led to some males forcing females into copulation. Most of the time the larger male wins and the smaller males are left with nothing. We can also define this system as short term polygyny.
The females reproductive stage lasts about 9 months, similar to humans. Females also don't show external signs of estrus or menstruation. Their reproductive cycles last about 30 days. Every 6-7 years a female will give birth to an offspring. They usually raise and stay in contact with their young for the first 7 years of its life.A female is considered to have reached adulthood when they have their first offspring. This whole process is very costly because it is so long and she is taking care of not only herself but of her infant as well.
