Brown Howler Monkey

Alouatta guariba

The brown howler (Alouatta guariba), also known as brown howler monkey, is a species of howler monkey, a type of New World monkey that lives in forests in south-eastern Brazil and far north-eastern Argentina (Misiones). It lives in groups of two to 11 individuals. Despite the name "brown howler", it is notably variable in colour, with some individuals appearing largely reddish-orange or black.

The two subspecies are:

What it does

Brown howler monkeys are folivores and frugivorous. The diet of the brown howler monkey consists primarily of leaves and trees. Of the food sources it seems that the genera Ficus, Zanthoxylum, and Eugenia are the most significant types consumed. Brown howler monkeys that live in higher latitudes tend to eat a lower percentage of leaves in their diet. Mature leaves are less nutritious and are more fibrous, than the preferred young leaves. A typical brown howler diet will also include mature fruit, wild figs, petioles, buds, flowers, seeds, moss, stems, and twigs The Atlantic forest, where brown howlers tend to live, has an increasing forest fragmentation. Forest fragmentation means that there would be a decrease in potential food supplies. The brown howler's feeding ecology, however, does not seem to be affected by the loss in habitat.
