Примечания
Recorded 7:36 am 10 cycles of song in first 16+ min of recording. voice announcement follows but I chose to stay in position and recorded another 4 cycles of song ... so combined. Bittern could be seen. I was about 60 ft from bittern. Peregrine Falcons can be heard in both sections, some sounds like young begging and some adult calling. Early in 1st section a deer can be heard snorting. Weather: fog and low 50s.
Подробности наблюдения
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."
