Habits and Lifestyle

Maroon leaf monkeys are arboreal and spend most of the time in trees rarely coming down to earth. They are social creatures and and live in groups that consist of 2-13 individuals. Each group is led by a dominant male. Maroon leaf monkeys are very territorial and chase away any intruders within their home range. Males produce a loud call to calim their territory and warn rivals away. These monkeys are active during the day and spend the majority of the time eating. During April, June, and August Maroon Leaf monkeys consume top soil of termite mounds. This way they obtain the minerals needed for a balance diet as the termite mound soil has high levels of calcium and magnesium.
