Media notes
One adult trumpeter swan silently floated on the surface of a pond for 10+ minutes. It gave 3 abbreviated calls immediately before taking flight. Then toward the end of the recording the swan one can hear longer duration calls with more widely spaced harmonics. Between the two call types, one can hear the pattering of the swan's feet on the water and the vibrato of the wings as the swan gained lift.
