Roosting and Foraging Behavior of Two Neotropical Gleaning Bats, Tonatia silvicola and Trachops cirrhosus (Phyllostomidae) 1

We studied roosting and foraging behavior of two Neotropical gleaning bats, ďOrbigny's round‐eared bat, Tonatia silvicola, and the fringe‐lipped bat, Trachops cirrhosus (Phyllostomidae). Techniques included radio‐tracking in a tropical lowland forest in Panama and analysis of data from long‐term studies in Panama and Venezuela. Day roosts of T. silvicola were in arboreal termite nests. T. cirrhosus roosted in a hollow tree. T. silvicola emerged late (ca 60 min after sunset), and foraged close to the roosts (maximum distance 200–500 m). T. cirrhosus emerged early (ca 30 min after local sunset), and foraged farther from its roost (>1.5 km). Both bats used small foraging areas (3–12 ha) in tall, open forest. They foraged in continuous flight (maximum 27–36 min) or in short sally flights (<1 minute) from perches (“hang‐and‐wait” strategy). The small foraging areas of these bats and their sedentary foraging mode most likely make them vulnerable to habitat fragmentation.
