Brumback’s night monkey^[1] is a nocturnal monkey species found in Colombia.

• Traditionally, it has been considered a subspecies of the grey-bellied night monkey (Aotus lemurinus).
• Still, recently, it has been argued that it should be considered a separate species.
• Like other members of its genus, this species is nocturnal. Its small round head is striped with black and dominated by two large brown eyes.
• The overall effect is not unlike an owl’s; the monkey’s eyes glow a reddish-orange in the reflected light.
• The white eyebrows are bushy, with a patch of darker coat between them. Its gray fur is described as thick and shaggy, and the animal’s underside is reddish brown.
• Its black-brown to orange tail is non-prehensile and invariably has a black tip. The Brumback’s night monkey has slender limbs with long, delicate fingers.

• The species gets its name in honor of the American naturalist and physician Roger Brumback.
• Nighttime comes foraging, when Brumback’s night monkeys move dexterously on all fours (quadrupeds) or hop through the tree canopy, up to 3 to 5 m (10 to 16 ft).
• They travel the same route every night; scientists believe that nocturnal monkeys memorize foraging routes as they travel by moonlight.
• The species belongs to the Aotus genus, the only truly nocturnal monkey in the world.
• Small family groups of up to 5 individuals, consisting of a monogamous breeding pair and their offspring, are the norm for these monkeys.
