Red Howler Monkey

The Red Howler Monkey (Alouatta seniculus) is the biggest of the howler monkeys.  It is found in the western Amazon Basin in Venezuela, Colombia, Ecuador, Peru, and Brazil. This monkey has thick, brownish to dark red fur, with gold or bright orange underparts, the color varying with the age and where the animal lives.  Males are bigger and their beard is darker and heavier. Their tails are very long and without fur on the underneath of the last third, providing better grip for holding onto branches. 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.
