Bat Activity Inventory at Pearl Harbor National Memorial - Acoustic Data - Dataset as delivered

We examined acoustic activity of the endangered Hawaiian hoary bat ('ōpe'ape'a; Lasiurus semotus) at at Pearl Harbor National Memorial (PERL) located on Ford Island, O‘ahu, Hawaii. The study area was located at the Ford Island Chief Petty Officer's (CPO) Bungalows Neighborhood, which covers approximately 4 acres and includes five historic CPO bungalows. Bat echolocation vocalizations were recorded at four acoustic stations (PERL1 - PERL4) located between 20 and 25 m above sea level, that operated nightly from June 2024 through December 2024. At station PERL-1 a total of 176 nights were sampled acoustically with 'ōpe'ape'a activity detected on seven nights. A total of nine 'ōpe'ape'a echolocation call events, zero feeding buzzes, and zero occurrences of multiple bats were documented. At station PERL-2 a total of 173 nights were sampled acoustically with 'ōpe'ape'a activity detected on seven nights. A total of eight 'ōpe'ape'a echolocation call events, zero feeding buzzes, and zero occurrences of multiple bats were documented. At station PERL-3 a total of 148 nights were sampled acoustically with 'ōpe'ape'a activity detected on six nights. A total of six 'ōpe'ape'a echolocation call events, zero feeding buzzes, and zero occurrences of multiple bats were documented. And finally, at station PERL-4 a total of 164 nights were sampled acoustically with 'ōpe'ape'a activity detected on six nights. A total of seven 'ōpe'ape'a echolocation call events, zero feeding buzzes, and zero occurrences of multiple bats were documented.
