The entry, giraffes, and orangutans were among Pittsburgh's less successful components when I toured the Zoo back in 2018, so to hear these will be first in line for the master plan sounds great! The mixed-species habitat that incorporates Malayan tapir is also a nice bonus, and I believe would make Pittsburgh the first in America to mix tapirs with great apes (am I sensing a renaissance for this species lately?). I find it interesting though that the siamangs are getting a whole new exhibit not even a decade after they were added to the Islands complex. Perhaps the gibbons could move out from Tropical Forest?
