Tree bats such as the eastern red bat, hoary bat and silver-haired bat exhibit south to north spring and north to south autumn migrations rather than engage in hibernation during the dormant season. Use of the Appalachian Mountains and Atlantic Coast have meant that wind-energy related mortality for the species is high. Efforts are underway to examine environmental and climate relationships to tree bat presence and movements to inform development of wind-energy best management practices and to better understand migration ecology.
