Habitat
They primarily inhabit tropical rainforests and riverine forests in the Amazon basin of South America, including countries like Brazil, Peru, and Colombia. These monkeys prefer areas with dense canopy cover and proximity to water sources, avoiding open or disturbed habitats.
Diet
Spix's night monkeys mainly eat fruits, insects, and leaves, with occasional small vertebrates like frogs or birds. They forage nocturnally, using their keen eyesight to locate food in the forest canopy, and often feed in small family groups.
Behavior
These monkeys are strictly nocturnal, spending days sleeping in tree hollows and becoming active at dusk to forage and socialize. They live in small, monogamous family groups of 2-5 individuals, exhibit territorial behavior through loud vocalizations, and communicate using a variety of calls to maintain group cohesion.
Conservation Status
The IUCN status is Least Concern, but population trends are decreasing due to habitat loss from deforestation and agriculture. Major threats include fragmentation of rainforest habitats and potential impacts from the pet trade.
