River pollution, destruction of riparian vegetation, and alteration of water courses.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
Unlike other bats, they perch in a single file on vertical surfaces, exposing themselves to view during the day.
