Let's talk about some cages, created by us or not. We will discuss the mix right or not. Some of my exhibits:
ENDANGERED AFRICA: Endangered african herbivores. Example:
Black rhinoceros, Rothschild's giraffe, Grévy's zebra, Giant sable antelope, Addax, Scimitar-horned oryx...
SMALL LAKE: Some semi-aquatic animals. Example:
Malayan tapir, Capybara, American beaver, Asian small-clawed otter, Mandarin duck...
CONGO FOREST: Congo forest ungulates and primates. Example:
Okapi, Bongo, Mandrill / African forest buffalo, Bonobo
MOUNTAINS: Mountain caprids and monkeys. Example:
Alpine ibex, Gelada / Markhor, Hamadryas baboon
COLD WATERS: Emperor penguin group and Beluga whale.
The Mandarin ducks would be otter chow, guinea fowls would likely be dinner for bonobos and mandrills, Geladas and Hamadryas baboons would likely fight, as would mandrills and bonobos, and black rhinos, African buffalo, and Grevy's zebras don't generally play nice with anyone.
