I wonder what information properties can be inferred from the characteristics of the avian audio signal.

Are birds sending specific data packets eg weather, food prospecting geocoordinates? Or are they entertainers like Frank Sinatra or Dolly Parton?

And could we decipher the language by studying data in context eg food hunts, mating rituals, predator warnings?

What might Claude Shannon make of these spectrograms?
