A tree roost for Commerson's leaf-nosed bat

A large insect-eating bat that is eaten by people in western and southern Madagascar 


Hipposideros commersoni is the largest insect-eating bat found on the island of Madagascar. Weighing around 60g and often living in large colonies in caves it is frequently hunted for its meat by people, especially in the west and south. Because of hunting pressure and loss of forests, where this species feeds, it is considered Near Threatened on the IUCN Red List.


Initially, we studied how this bat species used forest vegetation for roosting and feeding, working in both dry deciduous and humid littoral forests. We also looked at the diet of this bat species in these habitats. Our interest then turned to sites where this bat roosts in caves, and we focussed our efforts in the Anjohibe area north of Majunga. Although this is a Near Threatened species, hunting for subsistence use is legal between February and April. We are now trying to understand the impact of this hunting on the bat populations and the importance of the bat meat to human populations.
