Azara’s Night Monkey

About the Azara’s Night Monkey

Azara's night monkey (Aotus azarae), also known as the Azara's owl monkey, the southern night monkey, or the mirikiná, is a night monkey species from South America. It is found in Argentina, Bolivia, Brazil, Peru and Paraguay. The species is monogamous, with males providing a large amount of parental care. It is named after Spanish naturalist Félix de Azara. Although primarily nocturnal, some populations of Azara's night monkey are unique among night monkeys in being cathemeral: active at both day and night. The species is listed as Least Concern on the IUCN Red List.

There are three subspecies of Azara's night monkey. Aotus azarae azarae Bolivian night monkey, Aotus azarae boliviensis Feline night monkey, Aotus azarae infulatus The average weight is 1,290 g (2.84 lb) for male A. a. azarae and 1,310 g (2.89 lb) for female A. a. azarae. The mean body weight in A. a. azarae has increased by about 50 g (0.11 lb) in the past two decades. The increase is potentially linked to climate change, as warmer temperatures during the first year of life associate with higher body weights later in life.

For A. a. boliviensis, the mean weight is 1,180 g... Wikipedia →
