Hawaii Island, Hawaiian hoary bat acoustic data pre- and post-koa moth outbreak, 2007-2013

We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lupahoehoe 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 during 2007-2011 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 et al. 2020; see full citation below in the cross-references section). This data release consists of three tabular datasets including bat acoustic activity, mean monthly acoustic detectability, and acoustic detector locations.
