I have been presenting this as part of my talks on animal communication for
many years. I play a song bird, slow it to various speeds and compare the
result to a larger animal. Also, take a whale's songs and speed them up -
sounds like a bird. Doesn't seem all that new nor radical to me. I have
always assumed that the size of the animal places it in a temporal context
defined by the speed of neural impulses (which travel at pretty constant
rates, regardless of the animal).
To me, a hummingbird lives a very fast life, compared to us, and a whale
lives a slowed-down version of reality. The speed of their vocalizations
coincide closely with these temporal contexts.
