Jersey House the majority of their aye-aye elsewhere in the zoo, although I'm not sure if the other enclosure is reverse lighting or just in a very darkened building.
This enclosure has a darkened indoor bit, but the viewing is not great in that. The best time to see them outside is at about 5:30 but the rats are often out throughout the day. There are 3 other Aye Aye enclosures, 2 which are mixed with Giant Jumping rats, and 1 singley for Aye Ayes. There is also a Jumping Rat pair in another enclosure. All of these are on Malagasy time, so they are dark for most of the day. These are situated inside the manor house, towards the Lemur Woods.
Below is one of the darkened enclosures, with mixed species. This used to house the Rodrigues Fruit Bats.
