Field Frame Friday: Eat Dirt!

Geophagy, or eating soil, is observed in a variety of folivorous (leaf-eating) primates, including diademed sifaka (Propithecus diadema) in the Maromizaha Protected area. This behavior may help to protect against harmful chemicals found in the leaves that they consume.
