Did you know? Orangutans stay with their mother until they are about 7 years old! They spend that time learning everything from her – from what to eat to where to sleep. Because of how long offspring stay with their mothers, they only breed once every 7-9 years, which is the longest birth interval of any land mammal!

Wild orangutans are considered critically endangered.. Their biggest threats are due to many complex issues such as loss of habitat, illegal mining, and a high consumer demand for palm oil found in many consumer products.

As a member of the Association of Zoos & Aquariums, conservation is a priority for us. We provide financial support to projects that directly impact wildlife and protect wild spaces. The SAFE: Saving Animals From Extinction orangutan program was launched in 2018 to focus on these threats and identify how AZA institutions can assist in the recovery of the species. The founding AZA institutions include Henry Vilas Zoo, Kansas City Zoo, Como Park Zoo, and Seneca Park Zoo.
