Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island from 2018-2021. We examined resource selection at multiple spatial scales - perch location within a roost tree, roost tree, and forest stand. We used a discrete choice modeling approach to investigate roost selection and describe attributes of day-roost trees including those used as maternity roosts. ‘Ōpe‘ape‘a were found roosting in a variety of tree species and in an assortment of habitat types including native and non-native habitats. This data release consists of six tabular datasets: (1) Hawaiʻi Island ʻōpeʻapeʻa roost perch metrics, 2019–2021, (2) Hawai‘i Island ʻōpeʻapeʻa roost tree metrics, 2018–2021, (3) Hawaiʻi Island ʻōpeʻapeʻa random tree metrics, 2018-2021, (4) Hawaiʻi Island ʻōpeʻapeʻa roost stand metrics, 2018-2021, (5) Hawaiʻi Island ʻōpeʻapeʻa random stand metrics, 2018-2021, and (6) Hawaiʻi Island ʻōpeʻapeʻa roost thermal video monitoring, 2020-2021.
