Editing Aye-aye (section)

=== Social systems ===
The aye-aye is classically considered 'solitary' as they have not been observed to groom each other.{{Citation needed|date=April 2011}} However, recent research suggests that it is more social than once thought. It usually sticks to foraging in its own personal home range, or territory. The home ranges of males often overlap, and the males can be very social with each other. Female home ranges never overlap, though a male's home range often overlaps that of several females. The male aye-ayes live in large areas up to {{convert|80|acre|ha|order=flip}}, while females have smaller living spaces that go up to {{convert|20|acre|ha|order=flip}}. It is difficult for the males to defend a singular female because of the large home range. They are seen exhibiting polygyny because of this.<ref>{{Cite book |chapter=Patterns of Range Use and Social Organization in Aye-ayes (''Daubentonia madagascariensis'') on Nosy Mangabe |last=Sterling |first=Eleanor |date=1993 |title=Lemur Social Systems and Their Ecological Basis |pages=1–10 |doi=10.1007/978-1-4899-2412-4_1 |editor-last=Kappeler |editor-first=P.M. |editor-last2=Ganzhorn |editor-first2=J.U. |location=New York |publisher=Plenum Press |isbn=978-1-4899-2414-8}}</ref> Regular scent marking with their cheeks and neck is how aye-ayes let others know of their presence and repel intruders from their territory.{{r|Durrell}}

Like many other prosimians, the female aye-aye is dominant to the male. They are not typically monogamous, and will often challenge each other for mates. Male aye-ayes are very assertive in this way, and sometimes even pull other males away from a female during mating. Males are normally locked to females during mating in sessions that may last up to an hour. Outside of mating, males and females interact only occasionally, usually while foraging.<ref name="Garbutt1999" /> The aye-aye is thought to be the only primate which uses [[Animal echolocation|echolocation]] to find its prey.<ref name=nationalgeographic/>
