When great ape keepers at the Smithsonian's National Zoo were deciding how to add more variety and enrichment to their animals' lives, they turned to Orangutan Outreach and a program that had seen great success in 12 other zoos around the world: Apps for Apes.

With the tap of a finger, keepers are introducing the Zoo's six orangutans to iPads, which provide unique stimuli. They found that 36-year-old Bonnie likes to bang on the drums, 16-year-old Kyle prefers the piano and 25-year-old Iris is content to listen to the soothing sounds of the koi pond while watching animated fish splash.

"Apps for Apes fits perfectly in this new era of zoo keeping," said Becky Malinsky, great ape keeper at the National Zoo. "It's about changing up the day-to-day lives of our animals. We already vary their food, toys and social interactions every day, but the iPad offers another way to engage their sight, touch and hearing."

The Zoo began participating in the Apps for Apes program last year, when a keeper's family member donated an iPad to the Great Ape House. Malinsky and fellow animal keeper Erin Stromberg talked with the other program participants to determine which apps were the most popular among orangutans. In the past few months, the Zoo's repertoire has grown to more than 10 apps, including musical instruments, cognitive games, drawing programs and others. (Watch the video below)

"Apps for Apes is all about giving orangutans in human care choice over their environment," said Stromberg. "With the iPad, we're hoping to tap less into the critical-thinking outlet and more into a creative outlet. If they're engaged in an app, we'll keep going. If not, they have the choice to walk away."

As the world becomes ever more tech savvy, Apps for Apes also helps visitors connect with the orangutans and raises awareness about the challenges these intelligent animals face in the wild.

"Primarily, we want the Apps for Apes program to help people understand why we need to protect wild orangutans from extinction," said Richard Zimmerman, founding director of Orangutan Outreach. "We do that when we show Zoo visitors how similar humans and apes are, be it through observation, talking with wildlife experts or seeing the apes use the same technology we use every day."

Fans who want to provide the National Zoo's apes with additional engaging apps can purchase an iTunes gift card through the Giving Tree on the Zoo's website. Orangutan Outreach is also accepting iPad donations directly and will distribute the tablets to zoos around the country. Institutions that previously lacked the resources to participate would then be able to offer their orangutans the iPad enrichment experience.
