Hawaiian hoary bats (Lasiurus cinereus semotus) on Hawaii island were surveyed intermittently from 2004–2010. This data release is a single table of resulting bat location estimates, including date, time, coordinates for each location, and presumed bat activity at the time of collection. Nightly movements were documented for 30 Hawaiian hoary bats along the windward (eastern) side of the island of Hawaii. Each bat was fitted with a colored, split ring forearm band (Size X3; A. C. Hughes, Hampton Hill, United Kingdom) for long-term individual recognition and with a radiotransmitter (BD-2C model from Holohil Systems, Carp, Ontario, Canada). Bats were then released at the point of capture. Output from the transmitters was monitored with tracking receivers and 3-element Yagi antennae. Tracking stations were established at points within 5–300 m of activity centers for each bat and the tracking station coordinates recorded using Garmin GPS 12XL units (Garmin Corporation, Olathe, Kansas). Receiver stations were moved as necessary to improve reception. For a flying bat, bat locations were derived from a single bearing and signal strength (from Bonaccorso et al. 2015). Bonaccorso, F.
