It is unlikely that Bill Greaves went on about Bonobo phonology, since the bonobos that were on the project express linguistic meaning by pointing to lexigrams, not by controlling the vocal tract.

My false assumption when I wrote the above was that, although it is possible to study the phonetics of the languaging bonobos, they did not have a phonological system because they cannot realise the lexicogrammar phonologically.
The truth is almost the opposite. The languaging bonobos obviously do have a phonological system, since it is this that enables them to identify the words spoken by humans; and phonetic analysis provides an understanding of the physical limitations on realising their phonological system phonetically.
