If Savage-Rumbaugh or anyone else has actually tested a bonobo on any aspect of its syntactic knowledge, I'd be interested to know. I don't even think S-R herself makes claims for syntactic knowledge on Kanzi's part. If I recall her claim from a talk a few years back, it amounts to saying that just because Kanzi doesn't have syntax it doesn't mean he doesn't have language. I'm afraid I don't see the purpose in trying to determine who 'has' 'language'. Kanzi can, let us say, memorize symbols, and may even be said to know some words.
Chinchillas can tell the difference between voiced and voiceless consonants.
The honeybee's dance instantiates the property of displacement. It's not that dogs can't conceptualize, its that conceptualization can be defined so as to exclude behavior available to dogs. Let's share this with others. Even Chomsky is de-emphasizing transformations. Turing Machine equivalent, with context sensitive phrase structure in between, it is by no means clear that human languages are actually beyond the CFPS level.
