Summary

Habitat use, diet, prey availability and foraging ecology of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus, Vespertilionidae), was examined in the east Maui region inclusive of the Waihou Mitigation Area, Pu‘u Makua Restoration Area and the wind power facility operated by Auwahi Wind Energy, LLC. Research for the bat ecology study was provided by Auwahi Wind Energy, LLC, in order to fulfill requirements for mitigating bat fatalities under its approved incidental take permit. Acoustic monitoring over the three-year period demonstrated that bats are present and actively feed year-round at the Waihou Mitigation Area. This study included the first genetic analysis of Hawaiian hoary bat guano items, and broadly confirms the [...]

Purpose

Research for the bat ecology study was provided by Auwahi Wind Energy, LLC, in order to fulfill requirements for mitigating bat fatalities under its approved incidental take permit.These data were collected to assess bat habitat use, diet, prey availability and foraging ecology in a restoration area created for bat habitat mitigation. We surveyed bat acoustic activity and foraging activity over a three year period for a baseline observation of bat detection frequency and seasonal patterns. Insects were collected in two different seasons to describe the abundance and diversity of potential bat prey items in the restoration area. Bats were captured during the same periods to collect guano for dietary analyses. We used metabarcoding techniques to genetically describe insect order and families found the guano of Waihou bats, and compared these to a locally collected genetic insect barcode library, as well as the general types of available prey.
