Seventeen Species of Bats Recorded from Barro Colorado Island, Panama Canal Zone

A field report documents seventeen bat species from Barro Colorado Island, reporting capture methods using mist nets, banding, and selective specimen preservation for identification. It provides species accounts with notes on capture locations, roosting behavior, colony observations, body weights and reproductive condition, and frequency of occurrence. The authors compare results with earlier lists, update taxonomy, and note range extensions for at least one species. Observations include descriptions of roost sites such as tree cavities, tented palm fronds, leaf rolls, and buildings, plus behavioral remarks on daytime alertness and suction-cup attachment in certain species.
