I went to the SD Zoo last weekend and did a behind the scenes tour of Africa Rocks. I got some notes for you all:
1) There will be about 15 African Penguins including the 5 currently in the children's zoo. Penguins will open July 1.
2) Vervet Monkeys are on property and backstage. I saw them all, they have been there about a year.
3) It will be African Leopards on display. The Amur leopards will stay where they are on the Asian Leopard exhibit. There is a rumor (and only a rumor among keepers) of a black jaguar joining the leopards for ... reasons.
4) Gelada Baboons are the only animals not yet received.
5) The bridge construction is really the link for everything. Opening it will allow the canyon path to be completely open again, allow the Pandas to move back to their normal exhibit, and put Takin and Red Panda back on display. With that path open, the entry for penguins and the north end of Africa Rocks is good to go. There is an elevator to take visitors from the bottom of the canyon to the top of the bridge and treetop cafe. I'm guessing the zoo failed an ADA test.
6) A redo of the children's zoo/Discovery Outpost will be the next project after AR. Too many of the current animals on display are the demo-animals who need behind the scenes enclosures.
