After many years of not being able to go outside, the gorillas of Franklin Park Zoo now have access to the outdoors thanks to the brand new Gorilla Grove, which opened in April. The gorillas have access to Gorilla Grove daily, starting between 9 and 10 am. But some visitors have noted they haven't seen the gorillas inside or outside. That's because gorillas may choose to spend time in an indoor area, not visible to the public, while they get used to their new home, said a statement from Zoo New England. "When first introduced to Gorilla Grove, some members of the troop, including Little Joe and Aziza, acclimated to the new space right away, while it took some of the others longer to get used to the space, which is quite different from their indoor habitat," said Zoo New England.
