Lesser Sheath-tailed Bat

About this species

Habitat

Rock crevices, fallen trees and human-made structures; forages along edges

Range

Malay Peninsula, Borneo, Sumatra, Java, Sulawesi and other Indonesian islands

The lesser sheath-tailed bat is a small member of Emballonuridae, the sac-winged or sheath-tailed bats. In this family the end of the tail projects through the upper surface of the tail membrane rather than reaching its outer margin. The dependable distribution account spans the Malay Peninsula, including Myanmar and Thailand, Borneo and much of the Indonesian archipelago, explicitly including Sumatra, Java and Sulawesi. The opened sources provide no secure species-specific body measurements for the Sulawesi population (Wikipedia general species account).

A synthesis of Southeast Asian bat ecology lists rock crevices, fallen trees and human-made structures as roosts for Emballonura monticola. It classifies the species as an edge-space forager and describes its calls as frequency-modulated with a quasi-constant-frequency component. Those data distinguish its use of habitat edges from bats specialised for dense forest interiors. No diet composition, colony size or reproductive schedule is stated here because the sources opened did not document those details specifically enough for this species (Southeast Asian bat roost and foraging-guild synthesis).
