Very under rated mix, had the oppurtunity to see it at San Antonio Memphis- Wombat, agouti, three band armadillo, greater galago, striped skunk Capron Zoo- Indian crested porcupine, flying fox, wieds marmoset, sloth, green iguana, turaco, crowned pigeon, african starlings LCS-Bairds Tapir and Giant Tortoise Wilds- Bactrian Camel, Pere Davids Deer, Bison, Persian Onager Busch- Muntjac, Giant Anteater, Crowned Crane Gulf Breeze Zoo on the panhandle of Florida had some my favorite mixes: the capybara in with the Nile hippos (before its death), barasingha deer eating with gorillas (waterbuck were as well), snow and African leopards together
Newquay Zoo has Owstons civets and Prevosts squirrel together. Also crowned lemurs living with narrow-striped mongooses. All these species have bred successfully.
How about Bennetts wallaby, reindeer & llama, Barbary sheep & Persian fallow deer or Barbary sheep & waterbuck. All at West Midlands safari park. Better still Longleats mix of "big game" :- white rhino, Pere David deer, scimitar oryx & Watusi cattle, possibly Bactrian camel as well. They also have llama in the African exhibit & hippo & sea lion in half-mile lake!
Knowsley Safari Park: I saw photos in the gallery with Blackbuck, Nilgai, and Bennett's Wallabies. Lion Country Safari: Aldabra Tortoises, Pot-Bellied Pigs, Brazilian Tapirs, Fallow Deer, Florida Brown Pelican, Llamas, Marabou Stork, Common Rheas Busch Gardens Tampa: Caribbean Flamingoes, Grant's Zebras, Hartmann's Mountain Zebras, Scimitar-Horned Oryx, Vulturine Guinea Fowl
Toronto's oddest is probably the African Crowned Crane and Ringtail Lemur, temporary, I think, over the colder months. Safari Niagara has random hoofstock, compiled of Nilgai, Giant Eland, Alpaca, Addax and Scimitar Horned Oryx. Bird Kingdom has random birds of various contintents mixed in. When they had them, I spotted a Chestnut Mandibled Toucan preening a Silver Cheeked Hornbill
There is another aspect to this - there are quite a few species whose current range is only a remnant of one that once overlapped with animals that are now thought of as being from different parts of the world. Madagascar until only a few hundred years ago had Dipsochelys giant tortoises (which still live on Aldabra), and Choeropsis pigmy hippos (now strictly West African) for example. An historical perspective might make from some interesting exhibits - I would think that Giant Tortoise/Ring tailed lemur for example should probably work for one.
The Newquay Owston's Civets & Prevosts's Squirrels had a Tree Shrew in there at one time, and may still have. They also had Nene and Capybara together
Though definately not as odd as other exhibits on this thread, Lowry Park has Ring-Tailed Lemurs with African waterbirds like Greater Flamingoes, Shoebill Storks, Wattled Cranes, Saddle-billed Storks, African Spoonbills, and Great White Pelicans.
Well someone has tried this, the self-proclaimed world famous san diego zoo, to the tune of 44 million dollars in Elephant Odyssey and it is a colossal failure.
The aviary in Omaha has mute swans, wood ducks, golden pheasants, storks, flamingos, Egyptian geese, and tufted deer to name a few. It may not be a geographical arrangement but it is a beautiful, relaxing exhibit. The penguin and giraffe combination is a strange one. Years ago I remember peafowl in the Australian exhibit at Blank Park Zoo with wallabies and emus, although the peafowl may have been free-ranging.
Howletts Wild Animal Park, Kent Javan Langurs, Javan Gibbons and Capybara Pudu, Anteaters, Capybara Eastern Guereza and Gelada
Whats weird about Pudu,Giant Anteater and Capybara in a mixed exhibit,as they are all South American species,admittedly not all from the same area,but you do still see those species mixed a fair bit,in fact Chester have just recently added Pudu in with the Giant Anteater,so that visitors get to see something in the enclosure! Now if you wnat a weird mix Meerkat and White-lipped Tamarin is a weird mix to me,and one that I have seen at Shepreth in the UK.
I saw another wierd mix in Omaha; turkey vultures and prairie dogs and on that day there was a peahen with her chicks in the enclosure. The gaur exhibit also had prairie dogs in it.
