Most of your list is easy to find just walking around. The ones I've left in the
quote above are little trickier - of the other are housed in those little roundabouts you see peppered throughout the zoo and are frequently moved around.
The calamian deer are back by the children's zoo on your way into the zoo.
The uakari are in the Rainforest area, but behind a fence and set back from the path (right next to the howler monkey enclosure.) Bring binoculars or a zoom lens if you want a closer look.
The Chinese goral is outside of the LAIR house, but tucked onto an alternate path by the exit. The easiest way to be sure you don't miss them is to skip the entrance and turn left down the next path. They're in a small pool adjacent to the building.
The Chinese water deer are technically part of the Elephants of Asia exhibit, but all the way on the back of the elephant yard by the snow leopards. They can be quite shy and their exhibit is kind of tucked behind a bunch of educational displays about elephants.
I have no idea about the owl, let me know if you find it!
