Hawaiian hoary bat insect prey sampling with paired acoustic monitoring was conducted at Keaukaha Military Reservation (KMR) on Hawai‘i Island from May to August, 2018. At this property, a herd of domestic goats (occasionally mixed with domestic sheep) were rotated among grazing plots as part of a weed control program managed by Hawaii Army National Guard (HIARNG). Song Meter SM2BAT+ ultrasonic detectors (Wildlife Acoustics, Maynard, MA) with SMX-US ultrasonic microphones (Wildlife Acoustics, Maynard, MA) were deployed at a total of six stations, five monitoring stations (4E, 5F-I) and an additional reference station was established in an ungrazed area with similar non-native grassland habitat approximately 800-m...
Hawaiian hoary bats (Lasiurus cinereus semotus) were captured at multiple locations on the east side of Hawaii Island from May 2018 through September 2019. Radio transmitters were affixed to captured bats and, when possible, radio telemetry was used to locate bats in trees used for day-roosts. In 2019, three maternity roosts were identified however only two were suitable for acoustic recording. Acoustic detectors were used to record acoustic activity (i.e., echolocation pulses) at two maternity roosts. Song Meter SM4BAT FS ultrasonic recorders (Wildlife Acoustics, Maynard, MA) with SMX-US ultrasonic microphones (Wildlife Acoustics, Maynard, MA) were deployed within 5-m of each maternity roost tree and configured...
We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lāupahoehoe Forest Reserve on Hawai‘i Island during the 2013 koa moth (Geometridea: Scotorythra paludicola) outbreak. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level, that operated nightly from May 2013 through September 2013. We compared these data to data collected at similar locations in 2011 to determine the response of bats to increased moth abundance during 2013. In this abstract we refer to the Hawaiian hoary bat as a full species, Lasiurus semotus, following updated taxonomy for Hawaiian hoary bats (Pinzari...

This data set includes data derived from these acoustic recording stations. Each acoustic recording station was comprised of an acoustic recording...
Bats play crucial ecological roles and provide valuable ecosystem services, yet many populations face serious threats from various ecological disturbances. The North American Bat Monitoring Program (NABat) aims to assess status and trends of bat populations while developing innovative and community-driven conservation solutions using its unique data and technology infrastructure. To support scalability and transparency in the NABat acoustic data pipeline, we developed a fully-automated machine-learning algorithm. This dataset includes audio files of bat echolocation calls that were considered to develop V1.0 of the NABat machine-learning algorithm, however the test set (i.e., holdout dataset) has been excluded from...

Acoustic sampling for presence of the endangered Hawaiian hoary bat (Lasiurus semotus, also known as Aeorestes semotus) was conducted at 17 stations across four Marine Corps Base Hawaii (MCBH) properties on O‘ahu Island, Hawai‘i. Bats were confirmed as present at all properties; MCBH Kāneʻohe Bay on Mōkapu Peninsula, Marine Corps Training Area Bellows (MCTAB) in Waimanalo, Camp H.M. Smith in Halawa Heights, and Pu'uloa Range Training Facility (RTF) on the 'Ewa coastal plain. Hawaiian hoary bats were recorded in airspace at all four properties during important periods of Hawaiian hoary bat life history, including periods of pregnancy, lactation, and pup fledging; however, overall presence was low. Foraging activity...

Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 12 locations on U. S. Army facilities on O‘ahu Island, Hawai‘i. Bats were confirmed as present at 10 of these locations: Dillingham Military Reservation, Helemano Military Reservation, Kahuku Training Area, Kawailoa Training Area, Mākua Military Reservation, Schofield Barracks East Range, Schofield Barracks West Range, Schofield Barracks (Mendonca Park Housing), Tripler Army Medical Center, and Wheeler Army Airfield. Our acoustic sampling did not record bat vocalizations at Fort DeRussy or Fort Shafter. Despite the presence of bats at the above 10 locations, foraging activity as identified from characteristic...

These data are the location and date of collection of endangered northern long-eared bat Myotis septentrionalis echolocation passes when the automated bat identification software assessed species presence at a maximum likelihood estimator p-value of less than or equal to 0.05 consistent with the U.S. Fish and Wildlife Service monitoring guideline standards.
