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. 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, KAHO4) between 1 and 10 m above sea level. Nocturnal aerial insects were collected using a 22 W UV light placed above a funnel and bucket trap (Model #2851M, Bioquip Products...
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roost stand metrics were observed and collected from 2018 to 2021. We observed a total of 123 roost trees used by 90 bats (29 female; 58 male; 3 unknown). This data file includes data pertaining to roost stand metrics including, elevation, slope, canopy tree species, and mean canopy height.

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...

Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roost perch metrics were observed and collected from 2019 to 2021. We observed a total of 69 perches used by 52 bats (16 female; 22 male; 14 unknown) within 44 roost trees. This data file includes data pertaining to roost perch locations, dates, height, canopy cover, and aspect.
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roost tree metrics were measured and collected from 2018 to 2021. We observed a total of 56 roost trees used by 46 bats (18 female; 25 male; 3 unknown). This data file includes data pertaining to roost tree metrics including, height, diameter at breast height (DBH), tree species, canopy cover, and habitat classification.
Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roost stand metrics were observed and collected from 2018 to 2021. We observed a total of 123 roost stands used by 90 bats (29 female; 58 male; 3 unknown). We examined roost preferences at the stand-level with discrete choice analysis. Discrete model choice sets were developed based on distinct selection events and served as the observational units at each level, that is roost tree and roost stand. The number of choice sets was determined both by the number of unique roost sites to which a bat was tracked and the duration of the sampling period over which it was confirmed at one or more roosts....

Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island. Roosting bats were monitored by thermal video at 9 roost trees from 2020 to 2021. This data file includes data pertaining to thermal monitoring efforts including, location, nights sampled and rat presence.
