Bat News from the Field

  • Golden Frog Strategy Launched

    The Minister of the Environment and Forests officially launched the Golden Mantella Frog conservation strategy in a ceremony in Moramanga, on World Wetlands Day. The strategy was prepared by the Malagasy government, Madagasikara Voakajy and Conservation International, and sets out a series of goals and objectives for the next five years. The Golden Mantella frog is Critically Endangered on the IUCN Red List of Threatened Species and its remaining habitats in the Moramanga District are threatened by mining and deforestation.

  • International prize for our bat student

Select Species:

Commerson’s leaf-nosed bat (Hipposideros commersoni)

Description

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.

Conservation

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.

Description: If there are no available caves for roosting this species uses trees. In caves colonies contain hundreds of individuals but only single bats roost in each tree.

Description: This species feeds by hanging on vegetation, or in this case in a bungalow porch, and flies out into open areas to catch its invertebrate prey.
