Zoo Aye-Aye Care: Nocturnal Primates in Captivity

Aye-ayes are unusual nocturnal primates from Madagascar that present unique husbandry challenges in zoos, requiring specialized environments and foraging opportunities.

Key Facts

Aye-ayes are the worlds largest nocturnal primate, native only to Madagascar
They use echolocation-like tapping and an elongated middle finger to find wood-boring larvae
Aye-ayes have highly complex foraging behaviors that occupy much of their nightly activity
They are solitary and highly territorial, requiring careful social management in zoos
Currently Endangered due to habitat destruction and superstitious killing in Madagascar

Welfare Considerations

Aye-ayes require reversed day-night lighting schedules to match their nocturnal nature, allowing daytime visitors to observe natural behaviors. Foraging enrichment — particularly embedded grubs and syrup in drilled wood — is essential to satisfy their complex food acquisition behaviors. Solitary housing that respects territorial instincts prevents unnecessary conspecific conflict.

What You Can Do

Support accredited zoos with successful aye-aye breeding and husbandry programs
Advocate for habitat protection in Madagascar as a conservation priority
Encourage zoos to implement reversed lighting systems for all nocturnal species
