Abstract
This report summarizes bat and bird acoustic data collected between 19 May 2021 and 10 January 2023 at the E14 US Wind buoy. Results are presented cumulatively such that findings reported in prior reports are contained in subsequent reports. This report adds data from the second year of monitoring collected from 20 May 2022 to 10 January 2023. Bat and bird acoustic sensors continue to collect data for the rest of the second year at the time of this reporting. Here we present the bat and bird acoustic results associated with the above-water acoustic sensors deployed on the buoy. To date, we have recorded 67 bat and 131 bird detections, representing 18 unique species identified by their vocalization characteristics (Table 1). Bat acoustic detections were produced by three species: eastern red bat (Lasiurus borealis), hoary bat (Lasiurus cinereus), and silver-haired bat (Lasionycteris noctivagans). Eastern red bats and silver-haired bats accounted for the majority of bat vocalization sequences at 49.3% (n=33) and 41.8% (n=28) respectively. Bird acoustic detections were produced by 15 species (Table 1). Gull species accounted for 80.2% of all avian vocalization sequences, with most calls produced by herring gulls (n=97).
