Two Sumatran orangutans from Zoo Atlanta are playing video games as researchers plan to study cognitive, memory, reasoning and learning abilities of these intelligent species.

Zoo visitors are very curious to see four-year-old Bernas use his lips and feet to play a game on the touch-screen monitor. However, he is not as computer-friendly as his mom Madu who loves to spend time playing computer games.

According to AP reports, the orangutans use a touch screen built into a tree-like structure that is based on the same theme as their zoo habitat. And zoo visitors are able to watch from a video monitor fixed in front.

Authorities at the zoo are hopeful that the new method will make people aware of the wild orangutan population, which is endangered. The games that these animals play include choosing identical photographs or matching orangutan sounds with photos of the animals.

The ones who play well are rewarded with food and in yet another game these human-like animals draw pictures by moving their hands and other body parts around the screen. Zoo authorities also take out the print outs of their "special paintings" and put them on display in the zoo.

The orangutans are two species of great apes known for their intelligence and their long arms and reddish-brown hair. They are native to Indonesia and Malaysia.
