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]

Jan 31, 2012 · Owl monkeys Aotus spp have the potential to be a great model to accomplish a thorough integration of zoo and field research. Their most salient features are their nocturnal habits, monogamous social organization and paternal care, features that should make them of interest to the public.
Sep 14, 2023 · In this chapter, we synthesize data from anatomy, neuroscience, psychophysics, genetics, and behavioral ecology to review the key adaptations of the owl monkey visual system for dim light vision. First, we review Aotus evolutionary history and highlight the dramatic variation available in light environments at night.
Sep 14, 2023 · Aotus spp. serves as a remarkable nonhuman primate model, and researchers are particularly well-suited to integrate data from captivity and the field, due in great part to the extensive and well-habituated populations of owl monkeys at the DuMond Conservancy, OMBRR, and the Owl Monkey Project.
