Sep 14, 2023 · Current evidence indicates that owl monkeys (Aotus spp.) have species-rich, flexible diets. They can switch resources seasonally, consume ephemeral foods of many life forms, and locate food in small, degraded forests.

From the systematic monitoring of four groups of night monkeys over a period of approximately 1 yr, in two different tropical ecosystems, we found that these nocturnal primates spend a large proportion of the night resting. Night monkeys in lowland and highland forests had very similar use of time. These results suggest that night monkeys in tropic...
We found that night monkeys rely heavily on ripe fruits, and all study groups spent >60% of the feeding time eating fruits. Similar results have been reported for other groups of Aotus lemurinus (Castaño et al. 2010; Guzmán et al. 2016) and for other species of night monkeys such as A. azarae (Arditi 1992; Fernandez-Duque and van der Heide 2013) an...
The night monkeys have high behavioral plasticity and can be found in many types of forests, from highlands to lowlands, and from relatively undisturbed to heavily disturbed forest (Castaño et al. 2010; Defler 2010; Montilla et al. 2018). Home ranges range from 17.5 ha for Aotus brumbacki in Tinigua National Park in Colombia (estimated using minimu...
The distances traveled per night by the four study groups are partially consistent with the results of other studies of night monkeys. Nightly distances reported so far range from 252 m in Aotus nigriceps to 854 m in A. lemurinus (Castaño et al. 2010; Fernandez-Duque et al. 2008; Solano 1995). The distances we recorded for A. lemurinus groups CO1 (...

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. [11]
May 21, 2024 · In addition, except for Aotus lemurinus, there is little evidence of seed predation in owl monkeys, and thus (implicitly) for sclerocarpic harvesting. This chapter also makes clear that opportunistic and anecdotal observations on feeding in owl monkeys are valuable, albeit not ideal.
Night monkeys (Aotus), also known as owl monkeys, are New World primates found across Central and South America, ranging from Panama to northern Argentina. Belonging to the family Aotidae, they are characterized by their nocturnal lifestyle and distinctive owl-like appearance.
