Three cycles of song recorded around 7:36am. I was about 50 ft away. Peregrine Falcons continue to be heard in background. Weather: fog is beginning to lift, and low 50s.
觀察細節
total of 25 cycles of song over 55 minutes. recorded from 4 locations and approached incrementally. First at forest/marsh edge (80 ft), then into march at 60 ft, 50 ft and 40 ft away from the American Bittern. In all but the first location, I could see the bird. Calling was full bodied as described in "All About Birds" The male’s call is preceded by clacking and gulping. To accomplish the pump-er-lunk sound, the male inflates his esophagus by way of almost violent body contortions—opening and closing his bill as if lunging for flying insects—and then uses the stored air to unleash his call."
