Seasonal activity of bats at an Indiana cave

(Uploaded by Plazi for the Bat Literature Project) The activity of bats at Donnehue's Cave, Lawrence County, Indiana, was studied by netting the cave entrance 20 times at intervals from August 1970 to August 1971 and in February 1973. Seven species of bats were represented in the 440 captured; Myotis lucifugus was taken in the greatest numbers, followed by Pipistrellus subflavus, Eptescius fuscus, Myotis austroriparius, Myotis keenii, Lasiurus boreals, and Myotis sodalis, in that order. Data were gathered, by species, on nightly behavior patterns and sex ratios.
