Clear-winged woolly bat
The clear-winged woolly bat is a species of vesper bat in the family Vespertilionidae. It is found in Brunei, Indonesia, Malaysia, and the Philippines. Members of this species are relatively small, typically weighing about 4.5g and mainly forages in the understory of tropical forests. This species also presents a unique variant of echolocation that is a higher intensity and lower frequency than most other kerivoula calls. The sort range calls are distinguishable from the long range orientational echolocation calls by peak frequency and duration.
