=== Reproduction ===
In night monkeys, mating occurs infrequently, however females are fertile year-round, with reproductive cycles range from 13 to 25 days.<ref name="Dixson-1982">{{Cite journal|last=Dixson|first=A.

Birthing season extends from September to March and is species-dependent, with one offspring being produced per year; however, in studies conducted in captivity, twins were observed.<ref name="Dixson-1982" /> Night monkeys reach puberty at a relatively young age, between 7 and 11 months, and most species attain full sexual maturity by the time they reach 2 years of age. ''A. azare'' represents an exception reaching sexual maturity by the age of 4.<ref name="Dixson-1982" />
