• Guyanan red howler monkeys are social creatures in large groups of 3 to 10 individuals.
• Each troop has a hierarchy consisting of a single dominant alpha male, sometimes with 1 or 2 subadult males. The rests are females and their young.
• They are primarily passive, exhibiting unusually aggressive behavior. When aggressive interactions occur, it is typically between individuals of the same sex.
• Mature migratory males will attack the dominant male of a group for territory and females, with a frontal fight resulting in injury, loss of toes and tail, or even death.
• A solitary migrant female species that desires access to a group will exhibit submissive behavior and constantly follow the group for several days or even months, only to be constantly chased and bitten by the females of the resident group.
• Guyanan red howlers are arboreal and diurnal; they forage, travel during the day, and sleep at night, mainly in tree canopies 15 to 20 meters high.
