Order : CHIROPTERA
Family : Hipposideridae
Species : Hipposideros sp.


The images on this page are of a Hipposideros roundleaf bat from Perak, Peninsular Malaysia. The bat was photographed at dusk, as it emerged from an area of logged, lowland primary forest; it was heading towards an adjacent patch of secondary forest, presumably to forage for insects.

This bat may tentatively be part of the Hipposideros cineraceus complex ('Ashy Roundleaf Bat').


Figs 1 and 2 : Tentative Hipposideros cf. cineraceus roundleaf bat from Perak, Peninsular Malaysia; it was photographed at the edge of logged, lowland primary forest, as it flew across a rural road into an area of degraded secondary forest.

Fig 3 : Densely cluttered habitat at the margin of primary lowland forest, where higher levels of light promote rapid plant growth compared with the forest interior. Numerous species of Hipposideros roundleaf bat may inhabit the forest interior, but may rarely venture beyond its margins.

Fig 4 : Another example from the same area.
