re 'auditory fine structure', humans probably use this stuff too. check out 1970s work by smith etc on 'chimeric sounds', a study mixing low-frequency temporal envelope + high-frequency signal content from different speakers. humans apparently use one part for speech, the other for pitch + location.

sciam article hints at low harmonics mattering more to finches; some birds produce low harmonics via the 'pulse tone register', i.e. a mixing property of the dual syrinx. this is why birds sometimes sound like they've been run through an 8-bit encoder

- Doxin 4y agoThis video[0] seems relevant on the topic of similarity between human speech and birdsong. I'm not nearly smart enough to conclude if that similarity means anything or is just a happy coincidence. [0] https://www.youtube.com/watch?v=vYguVHUlGCA https://www.youtube.com/watch?v=vYguVHUlGCA
