Eidolon helvum Monitoring Network

A citizen-science project monitoring bat populations in Africa

Max Planck Institute of Animal Behavior, Dechmann Lab

Mission of the project

Straw-coloured fruit bats (Eidolon helvum) are the only known fruit bats to migrate over long distances and form large aggregations in Africa. Our project combines a volunteer network of colony counts with long-term GPS tracking (ICARUS) to better understand the drivers of these behaviors.

Straw-colored fruits bats are increasingly threatened by persecution and hunting. Monitoring colonies is essential for understanding if this keystone species is stable across Africa.
