Howling
According to National Geographic, these distinctive calls can be heard up to 3 miles away when group howling occurs. To make these loud calls, males have large throats and specialized vocal chambers that can heighten the volume and intensity of the howl. Brown Howler Monkeys often use their howls as a means to communicate group territorial boundaries.
Social Behavior
These monkeys are social by nature. They are found in small groups, either with males, females and infants, or a group of bachelor males. Males are incredibly territorial and may fight other Brown Howlers when a dispute over territory arises. Interestingly, female Brown Howlers are known to take care of other infants, even if they are not the mother. Female Brown Howler Monkeys typically give birth to only one monkey. During the infant monkey's first year, the males in the group aggressively protect their territory.
Gender and Size
The Brown Howler Monkey varies not only in terms of color, but also in terms of size when it comes to gender. The hyoid bone, or the bone situated in the middle of the neck, is larger in males than in females. This bone is used in relation to the howling calls of Brown Howler Monkeys. According to The Primata, this species is also sexually dimorphic in relation to size, with the male being larger than the female.
Prehensile Tails
Brown Howler Monkeys can use their strong prehensile tails to hold onto or hang from tree branches. Like having an extra arm or leg, their tails are helpful when grasping branches while traveling or feeding. The use of a prehensive tail also enables Brown Howlers to stay in the trees. Brown Howlers rarely descend onto the ground and prefer to stay in the canopy to feed. Along with leaves, they also eat flowers, small insects and fruit.
