Some Primate-with-non-primate mixes from a few Dutch zoos:
Amersfoort:
- Grey-handed night monkey with Two-toed sloth and Western woylie.
- Pygmy slow loris and Senegal galago with Malagasy jumping rat.
Apenheul:
- Coppery titi, Bearded emperor tamarin, Silvery marmoset and White-faced saki with Red-footed tortoise.
- Golden-headed lion tamarin, Pied tamarin, White-faced saki and Venezualan red howler with Red-legged seriema and formerly also Chilean pudu.
- Grey-handed night monkey with Two-toed sloth.
- Barbary macaque with Domesticated donkey. There used to be Barbary sheep instead of the donkeys.
- Northern talapoin and King colobus with African spurred tortoise.
- Black spider monkey with Capybara.
Aquazoo Leeuwarden:
- White-faced saki with Azara's agouti and Two-toed sloth.
- Lar gibbon with Harbour seal (The Gibbon moat is used as a seal separation enclosure).
Artis:
- Grey-handed night monkey with Brazilian porcupine, Two-toed sloth, Burrowing owl and formerly Brazilian tanager.
- Red-faced spider monkey with Great white pelican and Eurasian great cormorant. There's also Black-crowned night herons around, but I don't know if they can actually access the island.
Avifauna:
- Ring-tailed, Red-bellied and Red ruffed lemurs with Western Black-crowned crane, Black stork (formerly also European white stork), Vulturine guineafowl and Crested guineafowl.
- White-faced saki, Coppery titi, Bearded emperor tamarin and Venezualan red howler. Multiple ground birds used to be held here, but they were removed when a Tinamou drowned in the moat, not because of aggression with the monkeys. (Birds included Red-legged seriema, Elegant-crested tinamou and Nocturnal curassow).
Beekse Bergen:
- Hamadryas baboon with African elephant.
Blijdorp:
- Gelada with Blue-winged goose and Yellow-necked francolin.
- Ring-tailed lemur with Helmeted guineafowl
Dierenrijk:
- Crab-eating macaque with Asian elephant, Central European red deer and Chital.
GaiaZOO:
- Bolivian squirrel monkey and White-lipped peccary are held in the same region, though the Peccary are separated and I didn't see the Squirrel monkeys get anywhere near them. So I wouldn't call this one safe just yet.
- White-faced saki, Golden lion tamarin and Geoffrey's tufted-ear marmoset with Capybara
- Yellow-breasted capuchin with the same capybara (the monkeys are separated by a moat which the Capybaras can cross, quite creative).
Orchideeënhoeve:
- Red-bellied tamarin with Victoria crowned-pigeon, Violet turaco, Ringed teal, Crested wood partridge, Collared hill partridge and Toco toucan.
- Common marmoset with White-cheeked turaco.
- Ring-tailed lemur with American flamingo, Scarlet ibis, European white stork, Australian wood duck, Call duck, Gadwall, Goosander, Mandarin duck, Northern pintail, Ringed teal, Wood duck, White-faced whistling duck and Golden pheasant.
Ouwehands:
- White-handed gibbon with Great white pelican.
- Western lowland gorilla and King colobus with Meerkat (and formerly Red-crested turaco).
Wildlands:
- Wildlands' big greenhouse 'Rimbula' has three primate islands. One holding Ring-tailed, Black and Black-and-white ruffed lemurs, and the other two holding Colombian black spider monkey and Lar gibbon. There are many birds free-roaming in the greenhouse, but I saw Hottentot teal, White-winged wood duck and Laughing dove on the spider monkey island and Red-whiskered bulbul on the Gibbon island.
- Golden lion tamarin, White-faced saki and Bearded emperor tamarin with Azara's agouti.
- Peruvian squirrel monkey with Southern three-banded armadillo and Azara's agouti.
ZooParc Overloon:
- White-faced saki and Golden lion tamarin with Two-toed sloth and Grey-winged trumpeter.
- Coppery titi with Azara's agouti and Paraguayan tamandua.
- Ring-tailed, Red ruffed and Black-and-white ruffed lemur with Hermann's tortoise.
- DeBrazza's monkey with Reticulated giraffe and Dwarf zebu.
