Here’s a recording Wendy made on her phone on an autumn morning in our back yard. The chorus is made up of about ten Sulphur-crested Cockatoos, who politely allowed a few blow-ins (Australian ravens, aka crows) to take a couple of solos. I think you’ll agree the the results are worth listening to:
And because I know you want another spectral analysis, here it is with the cockies in blue and the crows in red:
So which is the more musical out of a cocky and a crow? Hmmm. The spectrum points to the crow because the cockies, admirable birds though they are, put out a blast right across the spectrum and therefore qualify more as noise than music.
