影音備註
At least one Common Nighthawk recorded at 2059 on 5/3/25. Recorded from a fourth-story window; never saw the bird but assumed it was circling the area. Presumed nonvocal "booming" heard during calls at 6 s and 30 s.
觀察細節
FOS. Heard only, including what sounded like the "booming" display, heard around 6 s and 30 s in the recording.
