For nearly a year, I forgot about this thread.
Oh well, time to continue:
1. African Buffalo
2. Sumatran Orangutan
3. Abynissian Ground Hornbill
4. Nyala
5. Jaguarundi
1. San Deigo Safari Park- large and naturalistic, the best I've seen
2. Ohama's Henry Doorly Zoo- amazing climbing opportunities for the orangutans and is well spaced out as well
3. San Deigo Safari Park- haven't seen a lot of enclosures for this species stand out, but the Safari Park comes to mind
4. Zoo Tampa- very naturalistic
5. Los Angles Zoo- It's one of those enclosures that you just enjoying visiting, plenty of spots for the Jaguars to hide and climb.
