I thought this video from Australia on roosting behavior of Kerivoula papuensis (should be Phoniscus papuensis) was interesting — http://www.youtube.com/watch?v=hqawKqjxBXk&feature=youtube_gdata. Worth keeping an eye-out for hanging/woven bird-nests as bat roosts where Phoniscus are found. We have found this once in Malaysia with Phoniscus atrox.
