Acoustic ecology is more concerned with human perception of soundscapes (R Murray Schaeffer et al.)

“...identity codas likely “serve multiple evolutionary functions within the umbrella of social bonding”, similar to human music.”p6

"Given evidence that sperm whale clan dialects are the product of cultural transmission via biased social learning (19), it has been posited that certain coda types act as symbolic markers of clan identity (16, 20–22), but quantitative evidence is lacking. However, recent work
showed that sperm whale clans in both the Atlantic and Pacific Oceans could be computationally distinguished by largely clan-specific “identity codas”, as opposed to “nonidentity codas”made by multiple clans (20). If these identity codas can be used by researchers to tell different clans apart, can they serve a similar function for the whales themselves?"p2

"The bowhead lives its life extremely slowly, becoming sexually mature at about age twenty-five, with females giving birth every seven years or so; if it avoids the whalers, a bowhead has a good chance of living well past a century.19 It is definitively the end of the slow life-history spectrum."p71

"The other baleen whales don’t form surface active groups when breeding in any obvious way, but this does not mean an absence of sociality. As we will discuss in the next two sections, sounds seem to be an important part of the mating process for baleen whales, and the whales can hear each other over large ranges. The animals may well be interacting in significant ways but be too far apart for humans to consider them part of the same group—or even to see them together. This mismatch between what is likely meaningful for the whales and what we humans can see is a problem for our understanding of all the cetaceans but perhaps especially for the baleen whales, whose sounds are so loud and carry over such long ranges."p74

If I was interested, Marko suggested I could download and try out with recordings I will make - but maybe not a priority. Marko has heard of it but niit used it.

CCNHM-1000 is a small odontocete skull including partial premaxilla, maxilla, nasals, frontals, left lacrimal, left jugal, parietals, left alisphenoid, left squamosal, petrosals, left stapes, incus, and malleus, fragments of tympanic bullae, and five teeth and fragments. Locality and Age CCNHM 1000 was collected by James L. Goedert from near the mouth of Murdock Creek (Field Number JLG-76) on April 26, 1986.
