Editing Night monkey (section)

=== Distribution ===
A primary distinction between red-necked and gray-necked night monkeys is spatial distribution. Gray-necked night monkeys (''Aotus lemurinus'' group) are found north of the Amazon River, while the red-necked group (''Aotus azare'' group) are localized south of the Amazon River.<ref name="Ferndandez-Duque-2012">{{Cite journal|last=Ferndandez- Duque|first=E|date=2012|title=Owl Monkeys ''Aotus'' spp. in the wild and in captivity|journal=International Zoo Yearbook|volume=46|pages=80–94|doi=10.1111/j.1748-1090.2011.00156.x|hdl=11336/101658|hdl-access=free}}</ref> Red-necked night monkeys are found throughout various regions of the Amazon rainforest of South America, with some variation occurring between the four species.
