Always improves the odds. ;-) The lower order harmonics can be so
"tight," dissonant and over-powering that they obscure the overtones
with the airier registers.

No Spotted Owls here in the Midwest. Their voice quality is very
similar to that of the Barred- both Strix species. So, that would
leave the GHO to make all four and the distant call at 01:52 sounds
very much like a GHO to me. Do the very distant descending "whiff"
calls at 2:38 sound a bit like regular paced snorts of a distant
white tail deer? Rob D.
