Abstract:
In Sri Lanka, bats represent approximately one third of the total number of terrestrial
mammals. However, detailed information on the biology and the ecology of bats in the
island are scarce. Bats are one of the least studied mammalian groups in the island where
previous studies were based on occasional or opportunistic collections. As such, it is
imperative to reevaluate the present status of Sri Lankan bats based on a systematic
survey. Therefore, in this study an island wide survey was carried out from 1995 to 1998,
to investigate the present status of Sri Lankan bats using current information on diversity,
distribution population data and to supplement the ecological and biological data, such as roostingo, bor eeding oand migration
