Goodwin KR and Kirschbaum AA. 2021. Acoustic monitoring for bats at Sleeping Bear Dunes National Lakeshore: Data summary report for 2015–2019. Natural Resource Data Series. NPS/GLKN/NRDS—2021/1323. National Park Service. Fort Collins, Colorado
The Great Lakes Inventory and Monitoring Network initiated an acoustic monitoring program for bats in 2015. This report presents results for 2015–2019 surveys at Sleeping Bear Dunes National Lakeshore. Acoustic recordings were analyzed using the software program Kaleidoscope Pro, and a subset of files were manually reviewed to confirm species identifications. The five bat species previously documented at the park were reconfirmed. These include big brown bat, eastern red bat, hoary bat, silver-haired bat, and little brown bat. Two additional species, the northern long-eared bat and tricolored bat, were also documented. Neither of these have been physically captured in the park, but our acoustic data suggest they are present. Although some acoustic files were identified by the software as Indiana bats, manual review did not confirm any files as this species. Activity levels for big brown bat, hoary bat, and silver-haired bat appear to be stable. Activity levels for eastern red bat, little brown bat, Indiana bat, northern long-eared bat, and tricolored bat show decreasing trends.
