Abstract
This report summarizes bat and bird acoustic data collected between 19 May 2021 and 19 May 2022 at the E14 US Wind buoy. Results are presented cumulatively such that findings reported in prior reports are contained in subsequent reports. Bat and bird acoustic sensors were deployed with the E14 US Wind buoy on 19 May 2021 and continue to collect data for 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 37 bat and 123 bird detections, representing 17 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). Silver-haired bats accounted for 67.6% (n=25) of bat vocalization sequences. Bird acoustic detections were produced by 14 species (Table 1). Gull species accounted for 83% of all avian vocalization sequences, with most calls produced by herring gulls (n=94).
