Here is a really cool video that shows Orangutans and how they can mimic human behavior. I myself have been able to witness Orangutans mimicking human behavior. I was observing an Orangutan at Busch Gardens in Tampa Bay Florida. The Orangutan took a shirt that was given to her as a form of enrichment (aka a toy) and she took the shirt and ripped it in half (orangutans are very strong) and she tied it to a branch in her enclosure and made a swing out of it. She sat there for a good 10 minutes swinging around until she got bored then untied the shirt and made a necklace out of it. It was very funny to watch. It really goes to show that if you observe these animals for a while (and they observe you back) they will pick up on human tendencies.
