Then the aye-aye inserts its slender and highly flexible third finger into the hole, and when the prey is located, it is hooked with the tip of the finger and removed. Unlike other lemurs, aye-aye breeding can occur at any time of year. The first recorded birth of an aye-aye in human care was Blue Devil in , whose mother, Endora, was captured in Madagascar while pregnant.
Angelique, born at Duke in , was the first aye-aye ever born to parents who themselves were born in human care. In the wild, infants are weaned as early as 7 months, but they will continue nursing as long as they remain with their mothers and do not have any younger siblings.
In human care, females give birth every years. Aye-aye females reach sexual maturity at around 2 years old. The gestation period is, on average, days. While the majority of their time is spent in the trees, traveling on the ground is reasonably common.
Males have huge home ranges, between to acres and ha , while the home ranges of females are much smaller, usually between 75 to acres 30 and 50 ha. Female ranges do not overlap with those of other females, but they always overlap that of at least one male. Aye-ayes sleep in elaborate tree nests during the day, with different animals using the same nest on different days. Wild aye-ayes spend most of their lives alone. The only social interactions occur during courtship and when an infant is dependent on its mother.
During these interactions, females are considered to be dominant over males, giving them preferential access to food. When aye-ayes get excited or agitated, their long, mostly white guard hairs stand on end and give the poofed-up lemur the appearance of an animal twice its actual size! Size relative to a 6-ft man:.
