Great Ape Trust of Iowa is home to three orangutans. Azy, an adult male, arrived in the fall of 2004 from Smithsonian's National Zoological Park in Washington, DC.  He and Dr. Robert Shumaker have been research partners for nearly 25 years. Knobi, an adult female, came to Great Ape Trust in early 2005 from Henry Doorly Zoo in Omaha while Allie, an adolescent female, arrived from the Denver Zoo in late 2005.
