Saccopteryx leptura

Lesser Sac-winged Bat

Order: Chiroptera
Family: Emballonuridae

 

Conservation Status: Least Concern.


Like the slightly larger Greater Sac-winged Bat, the Lesser Sac-winged Bat is a forest dweller, locally common in some lowland forests. Family groups, usually a male, female, and their offspring, roost together in a tree. They feed among the trees early in the evening and fly above the canopy to continue feeding later at night, trying to keep other family groups away from their foraging territory. Both species have two zigzagging lines of white fur on their back, running from behind their ears almost to the tail, and are sometimes called "white-lined bats."
