The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups.
This study examined the behavior of Hawaiian hoary bats at wind turbines operated by Auwahi Wind Energy, LLC, on southern Maui Island, from August to November 2018. The research was conducted to assess the risk that wind turbines pose to bats at the wind energy facility, and compared information obtained from both acoustic monitoring and thermal videography. The dataset for this release comprises the thermal video data compiled for all individual bat detections. It differs from the data presented in "Hawaii hoary bat nightly acoustic-visual detections and conditions, Maui Island 2018" in that the latter tallies total bat detections per night and turbine for both acoustic and video sampling methods.
