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 '\u014dpe'ape'a activity detected on seven nights. A total of nine '\u014dpe'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 '\u014dpe'ape'a activity detected on seven nights. A total of eight '\u014dpe'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 '\u014dpe'ape'a activity detected on six nights. A total of six '\u014dpe'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 '\u014dpe'ape'a activity detected on six nights. A total of seven '\u014dpe'ape'a echolocation call events, zero feeding buzzes, and zero occurrences of multiple bats were documented.", "distribution": [{"@type": "dcat:Distribution", "description": "zip file of acoustic data and metadata files for the Bat inventory at Pearl Harbor National Memorial", "downloadURL": "https://irma.nps.gov/DataStore/DownloadFile/756764?Reference=2317584", "format": "zip", "mediaType": "application/zip", "title": "PERL_AcousticData.zip"}], "identifier": "http://datainventory.doi.gov/id/dataset/NPS_DataStore_2317584", "issued": "2025-06-04T00:00:00Z", "keyword": ["Acoustic survey", "Bat survey", "Echolocation", "Hawaiian hoary bat", "IMD", "Lasiurus semotus", "NPS", "NPS Inventory and Monitoring Division", "NPS Species Inventory Program", "National Park Service", "Open-format", "PERL", "Pearl Harbor National Memorial"], "landingPage": "https://irma.nps.gov/DataStore/Reference/Profile/2317584", "modified": "2025-06-04T00:00:00Z", "programCode": ["010:118", "010:119"], "publisher": {"@type": "org:Organization", "name": "National Park Service"}, "spatial": "-157.9512,21.3638458,-157.936554,21.36931", "temporal": "2024-06-13/2024-12-11", "theme": ["Generic Dataset"], "title": "Bat Activity Inventory at Pearl Harbor National Memorial - Acoustic Data - Dataset as delivered"}
