观察细节
Drumming started 5:48, till about 6:10. Recording to be uploaded. The drumming occupies only the very lowest frequency band. However, around 0:30-0:40 you can see (and hear if you turn the playback all the way up) the accelerating wing-beats. Apparently it was doing some other random wing-beats earlier in the recording; we (or at least I) did not hear this earlier activity. There were 8-10 audible bouts of the classic drumming whirr.
