slightly over 1 month we have been monitoring a make and female violet-green swallow creating a nest under our roof. Today the fledglings hatched. Adult (female) can be heard along with fledglings. We witnessed her under rooftop, then began recording at close range (within a few feet probably 1 meter). Use a Zoom H4n recorder and a 2 meter monopod
