Do you think all the frequencies are happening on this one mechanical device, or do you think there are multiple animals making the call at different frequencies? I'm leaning towards the wobbles being the higher pitch sounds, and the "progressive buckling" being the lower pitch sound.. I think it would be SO cool to partner up with someone and write a paper on this.
