@Mr Gharial This is just the main path of the building. The exhibit to the left in the photo had a Yellow Backed Duiker, and I've seen a Red Billed Hornbill along with it. Although this building also houses a Dwarf Crocodile, Giant Elephant Shrew, along with multiple small terrariums, and a indoor Okapi space.
@Micah Satvedi This exhibit is way too small for a yellow-backed duiker. It used to seasonally hold royal antelope, but that animal passed away a few years ago. Other than that red-flanked duikers have always occupied the space whenever they are indoors, along side a pair of red-billed hornbills.
Even without the pangolins, this building is one of the highlights of the zoo for me, as I can appreciate the focus on rather unknown, niche species.
