Could someone send me a link to the ISIS if they have a website? I've never heard of it, but it sounds like it has lists of animals from each zoo. In the hyena exhibit they will display the male by himself, but other times it will be the mother and her baby. When I said lone hyena, I meant the one that switches out with the macaques in Vanishing Animals. That hyena looks like he has scars so maybe he didn't do well with the other hyenas and they found a new location for him.
I'm not sure why they separate the two elephants sometimes. I find it a bit cruel, but hoping there's a legit purpose for it. The Polar Bears do tend to pace in the summer, but they seem very happy and active in the winter. The funny thing is I saw the male Polar Bear in the morning and he was swimming and playing in his pool happy as can be. The Polar Bears have access to both exhibits, I saw them in the bigger one in the morning, but they decide where they want to go. Not sure why Nanuq usually picks the smaller one. Not sure about the ocelot since you went in the afternoon; Pedro should have been out by 3. I felt one afternoon I didn't see either all day. Not sure what's going on with the routine. In Vanishing Animals, did you see the Spectacled Bear or Manned Wolf? As for Heritage Farm, the canal is stationary. I think they might have planned to have it actually move down the canal, but they probably scraped the idea.
I can't wait to see your videos.
