Monkey sleep, monkey do: how primates choose their trees

in #grfast6 years ago

Primates don’t monkey around when deciding where to spend the night, but primatologists have had a poor grasp on what drives certain monkeys toward specific trees. Now, two extensive studies of Indonesian primates suggest that factors in selecting trees each evening are site-specific and different for each species—and that some overnight spots result in conflicts between monkeys and humans.

“We have to understand what monkeys need [in order] to sleep to know what we have to protect,” said primate scientist Fany Brotcorne of the University of Liège in Belgium, leader of one of the research teams, in an interview with mongabay.com.

When monkeys choose their evening perch, they weigh more than just comfort. The main factors scientists suspect are safety from predators, distance to feeding grounds, human interactions, insect avoidance, and competition with other primates.
