@Cat-Man I'll copy and paste a paragraph from my review of Berlin Tierpark from my Snowleopard's 2019 Road Trip thread (I visited 95 zoos in 33 days):
"The Monkey House is one of the highlights of the zoo, with a large Gelada exhibit that doesn’t even make it onto the zoo’s map. There’s nothing quite like surprising a Canadian zoo enthusiast by rounding a corner to see a troop of Geladas with a minimal water barrier separating one crazy monkey species from another! The zoo’s Monkey House is a brand-new development, in terms of an update on an existing building, and for the most part it is very well done. Species list (10 primate species + 6 other species): Gelada, Diana Monkey, Red Howler Monkey, Yellow-breasted Capuchin, White-faced Saki Monkey, Silvery Marmoset, Mongoose Lemur, Collared Brown Lemur, Red-bellied Lemur, Black Lemur, Southern Tamandua, Spotted Paca, Azara’s Agouti, Radiated Tortoise, Amazon Milk Frog and Banded Day Gecko. The Monkey House concentrates on fewer species than many other similar buildings in German zoos, but what it does it does very well indeed. In December 2017 a permanent addition to the Monkey House was added in the form of #discoverConservation, which is a series of signs and multi-media stations that highlight conservation issues undertaken at the zoo. Elsewhere in the zoo is a Pig-tailed Macaque (bachelor group) in another new-looking exhibit, Golden-handed Tamarins in the Pachyderm House, Red-naped Mangabeys, plus a Lemur Woods area (Black and White Ruffed/Red Ruffed), a Ring-tailed Lemur exhibit, Barbary Macaques and a White-handed Gibbon island. Berlin Tierpark therefore has 18 primate species, including 7 lemur species, but no great apes whatsoever."
