Aye-ayes are nocturnal lemurs with highly specialised percussive foraging behaviour using an elongated middle finger to extract wood-boring insect larvae. Their unique needs and cultural significance in Madagascar make both captive care and in-situ conservation challenging.
Aye-ayes in captivity require nocturnal house conditions with simulated tree bark containing embedded insect larvae or nut paste to support the percussive foraging behaviour that is central to their cognitive and physical welfare. Enclosures must provide varied branch diameters and complex three-dimensional climbing environments. Social management is challenging — aye-ayes are largely solitary and require individual housing with carefully managed brief social encounters. Conservation education addressing the fady superstition has reduced killing rates in some Malagasy communities, demonstrating that cultural engagement is as important as habitat protection.
