Well in San Francisco they now have a pair of orangutans, their old chimps, and these new ones rotating between a single basic indoor dayroom, a elevated walkway, and an average outdoor yard. The plan was to build a new complex for chimps and then bring in orangutans, but plans appear to have changed and now the orangutans live in the same holding building that was derided as inhumane for the chimps.
And instead of finishing up another new exhibit & holding building for these apes, they invested in other projects such as the snow leopard expansion & Madagascar complex.
