It lives in groups of three to nine individuals (usually five to seven).{{cite book | title = Neotropical Rainforest Mammals | year = 1997 |author1=Louise Emmons |author2=Francois Feer |name-list-style=amp }} The groups are [[Polygyny in animals|polygynous]], with only one or two males and the rest females and their offspring.{{cite web |url=http://animaldiversity.ummz.umich.edu/site/accounts/information/Alouatta_seniculus.html |title=Alouatta seniculus information |author=Normile, R.

The females of the group are in charge of the offspring. Venezuelan red howlers are most active in the morning, when the group is on the move to find another feeding spot. These howlers are famous for their "dawn chorus". These roaring and howling calls are performed mostly by the males in the group. The roars can be heard up to 5 km away in the forest, and make their presence known in the area. This is also used to prevent confrontations between groups, which will prevent energy loss by avoiding physical fighting. Because of their low-sugar diets, conservation of energy is key. The calls also help in the scattering of the groups and lessens the competition over food.
