Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae) were examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu‘u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. The study was conducted to inform the mitigation and management requirements of Auwahi Wind Energy, and fulfill requirements for mitigating bat fatalities under its approved incidental take permit. Acoustic monitoring over the three-year period demonstrated that bats are present and actively feed year-round at the Waihou Mitigation Area. This study included the first genetic analysis of Hawaiian hoary bat diet items, and broadly confirms the major arthropod orders (Coleoptera, Lepidoptera, Diptera, Hemiptera, and Blattodea) found in previous microscopy-based studies of guano samples.

We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Honōkohau National Historical Park located in the coastal region of Kailua-Kona, Hawai‘i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1 and 10 m above sea level, that operated nightly from November 2013 through February 2015. This data set includes data derived from these acoustic recording stations. Each acoustic recording station was comprised of an acoustic recording unit (SM2Bat+ Song Meter Digital Field Recorder, Wildlife Acoustics, Concord, MA) programmed to record between 10 and 100 kHz. Each recording unit was deployed in a waterproof housing and powered by a 6 V external battery with solar panel for recharging. An ultrasonic microphone (SMX-US, Wildlife Acoustics, Concord, MA) was mounted on a pole 2 to 3 m above the ground and connected by cable to the recording unit. Upon detection of a vocalizing bat, recording was triggered, and a call file was stored with the corresponding date and time on a secure digital (SD) memory card. SD memory cards were replaced every 2-3 months during which times quality checks on microphones were also made. Each recording unit was configured to operate from one hour before local sunset until one hour after local sunrise.

The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations (KAHO1-KAHO7) between 1 and 10 m above sea level, that operated nightly from November 2013 through February 2015. Nocturnal aerial insect collection occurred in January and April (2 or 3 nights each) and in July and November (1 or 2 nights each) in 2014. Insects were collected at three stations KAHO1, KAHO3, and KAHO4. These data summarize the seasonal presence of the Hawaiian hoary bat and nocturnal, aerial insect prey at Kaloko-Honokohau National Historical Park over a 15-month period from November 2013 to February 2015. This data release consists of three tabular data sets including bat acoustic activity, collected insect counts, and collected insect dry biomass data.

This data set provides the locations and corresponding elevations where insect collection, acoustic recording, or Hawaiian hoary bat (Lasiurus cinereus semotus) captures occurred as part of a study of bat activity, diet, and prey availability in the Waihou Mitigation Area, Maui. To fulfill requirements for mitigating bat fatalities under it's approved incidental take permit, Auwahi Wind Energy LLC (Auwahi Wind) provided funding for research of Hawaiian hoary bat ecology. Data from this study were collected to assess bat habitat use, diet, prey availability and foraging ecology in a restoration area created for bat habitat mitigation. We surveyed bat acoustic activity and foraging activity over a three-year period for a baseline observation of bat detection frequency and seasonal patterns. Insects were collected in two different seasons to describe the abundance and diversity of potential bat prey items in the restoration area. Bats were captured during the same periods to collect guano for dietary analyses. Please reference the associated metadata and datasets that correspond to this publication for more information on how these locations were used.
