Spring 2025 nightly Dickcissel calls (red) tallied from six acoustic monitoring stations in the LRGV transect overlaid on the spring 2024 results (green/yellow) for the same six stations. Similar to 2024, each station uses an Old Bird 21c (v2020) microphone to receive sound from the night sky and the audio signal is fed to a Dell Latitude (7200 series) laptop to record and process the sound. The 2025 Dickcissel night flight call data shown were collected through automatic detection by "Dick-r" software program operating 8 hours per night (9p-5a CDT, GMT -5). The 2024 data were extracted with "Dick-r" (yellow line) and "Nighthawk 3.0" (green line) software programs over the same span of night across the same transect of six acoustic stations as in 2025.
