Listen to the passage of the flock of small birds near the beginning of
C3, there's a whole bunch of quieter wing sound that's similar to the
loud one.
One could make a whole study of different wing sounds, though I think
the chances of identifying species that way are slim.

Unfortunately I only have Stokes Eastern, which does not have the
species. I did do a search of the internet and found a dozen or so
recordings. None resemble what I'm talking about. All the examples I
found a sonogram reveals the call to be strongest around 3khz, and such
a call does occur in my recording frequently.
The call I'm noting is shorter, and at 2khz. In C1 the best ones are at
23, 34, 51, & 58 seconds roughly.
