Aye-aye is present in Ueno and Taipei in Asia.I plan to create a special thread for my questions.
More related to the subject: Do you know where the ayes ayes are currently hosted in the world?
And what is the best installation you have seen for this primate?
On another note, the Northern Dry Zone Slender Loris (Loris lydekkerianus nordicus) is kept in a few places in Europe, but is it in America? I remember seeing it as a kid in the World of Darkness at the Bronx Zoo, but that building closed over a decade ago, so I have no photos of it.
No.Doesn't Ueno have an outdoor exhibit?
There are 56 aye-ayes in total outside of Madagascar. 20 in Europe across five holders, 25 in the US across seven holders, 10 at Ueno, and one at Taipei.
Also found at Bird Park Vorobi in Europe
Listed at Dresden as well as 11 collections world wide
Black Lion Tamarin
I'd be somewhat surprised were this to be accurate - although it would be a nice surprise!
Assam Macaque
This one doesn't quite ring true either - certainly the species was not held when I visited in October 2018, and I have heard no reports of fresh imports.
Before I get the question about which zoos and how many:
Four at Frankfurt
Three at Bristol
Three at Chester
Eight at Jersey
Two at London
Two at Cincinnati
One at Cleveland Metroparks
Three at Denver
Nine at Duke Lemur Center
Two at Henry Doorly
Four at Philadelphia
Four at San Diego
