[time-nuts] woodpecker sounds

[jimlux]

Cornell has recordings of thousands of bird sounds..

and then, the frequency of woodpecker "drumming" has been the subject of 
some study

https://sora.unm.edu/sites/default/files/journals/condor/v100n02/p0350-p0356.pdf

reports, for instance, that Pileated woodpeckers drum at 14.2 Hz 
(+/-0.4Hz) in a burst of 1.7 seconds (+/- 0.3)

although the analysis not by time-nuts, since their statistical analysis 
of drumming rates is not of the kind with which *we* are familiar. This 
is no surprise: over the past 3 years, I've been looking at literature 
on heart rates, and out of hundreds of papers, I think only a few 
mentioned the power spectrum in terms of an oscillator model of any 
kind.  For many years, physiologists eschewed the use of mathematical 
models.

Anyway, the paper above was trying to see if they could separate species 
based on the oscillator characteristics.  A ton of hand waving at the 
end about why different species might drum at different rates in 
different places  in different places.


A new avenue of investigation for time-nuts to pursue.  Who knows, maybe 
you could develop the first GPSDWO (GPS disciplined Woodpecker Oscillator)
