Melbourne Zoo in Australia is notorious for this.
They have the following double ups:
-Aldabra Tortoise
-Tasmanian Devil
-Sumatran Tiger
- Squirrel Monkey
- Kookaburra
- Meerkat
- Coati
- Peccary
I haven't even mentioned the all bird species and reptile species. Regarding the reptiles, all are displayed in the Reptile House, and some also have exhibits elsewhere in the zoo.
The problem for me is the fact that there's absolutely no need for these double ups. None of the above species are breeding at such high rates, and so the zoo dosen't have a large number of any of those species. The zoo has just displayed them there to fill up an empty enclosure.
