My revised thoughts for the Animals in this Pack.
Coyotes: Not much of a Popular Zoo animal, but because they are adaptable, they can be placed in any biome you can think of: Desert, Forest, Wetland, Grassland, Tundra, and even Rainforest in your North America Region. The Rig Animation can give way to Jackals and perhaps the Ethiopian Wolf, which are closely related to Coyotes and Wolves and are very Endangered. (I see them in my neighborhood and hear them howl every night)
Greater Rhea: It's the Last of the Great Ratite Flightless Birds that is highly requested, which started off with the Ostrich (Base Game) Southern Cassowary (Australia Pack), Emu (Grasslands Pack), North Island Brown Kiwi (Oceania Pack), and now the Rhea completes it, the Tinamou will have it's chance and would be great addition for the South American Grasslands. (I see them at the Santa Ana Zoo)
Bighorn Sheep: It's one of the Original Zoo Tycoon Animals, and it is the Hardest to build a proper habitat for them. It's also a classic Mountain Sheep, and I think people want this instead of the Dall's Sheep when the first pack came out. (I see them at the Los Angeles Zoo where I volunteer, and they are the Mascot of the Los Angeles Rams)
American Flamingo: The American or Caribbean Flamingo has much brighter crimson pink colors than the Great Flamingo, which are more pale pink, and the news of their comeback and native status in Florida. I read somewhere about an update regarding skin variations for their animals; they have yet to add skin variations for animals like flamingos that get their color from the food they eat based on diet. Perhaps they'll add that here if I'm correct. I would like to see Lesser Flamingos added as they are a pinker pink, and they can be used in comparison to the Greater Flamingos
White-face Saki Monkey: We need another South American Monkey in the South American Rainforest to go with the Colombian White-faced Capuchin Monkey. There is a sexual dimorphism between the males and females; they mate for life, and their rigs and the Capuchins' rigs can give way to more monkeys and primates. (The Los Angeles where I volunteer has them)
Bush Dog: Another South American Canid to go with the Maned Wolf, which is closely related. These terrier-sized dogs may be small, but they are formidable in a pack and can swim. Rare in North American Zoos, but common in European zoos.
Ocelot: Most Zoos, including the Los Angeles Zoo, where I volunteer, and the Santa Ana Zoo, have this small spotted wildcat to compare with the larger Jaguar. Ocelots live in rainforests as well as scrublands, wetlands, and deserts, and they are very rare in the Southwestern USA, North America, like Texas. Hopefully, we might see more spotted wild cats like Margays.
