An 11-year-old orangutan named Allie from the Denver Zoo is recovering from a viral neurological disorder in her legs at the Great Ape Trust of Iowa.
Zoo officials thought the orangutan would benefit from the equipment and social setting at Great Ape Trust, where it has shown significant progress since arriving a month ago, The Des Moines Register reported.
Trust scientist Robert Shumaker said the primate is once again showing good mobility.
"She can go anywhere, anytime," Shumaker said, adding the orangutan is scampering about the three-story building's network of suspended fire-hose "vines," ladders, platforms and grates.
Orangutans use their arms to bear most of their weight, so the animal's still-recovering legs have been enough to help her move around, he said.
