The aye-aye is one of the most unusual primates in the world, with specialized foraging adaptations that present unique welfare challenges in captivity.
Aye-ayes present unique zoo welfare challenges due to their nocturnal lifestyle, specialized foraging needs, and sensitivity to social structure. Reversed light-cycle management allows visitors to observe active behavior while maintaining natural rhythms. However, many facilities lack adequate space or enrichment complexity to support tap-foraging behavior — a highly motivated activity that aye-ayes perform extensively in the wild. Inadequate foraging enrichment leads to repetitive behaviors and apparent frustration responses.
