Bee dances are a fascinating topic, but the evidence is still inconclusive - there is some evidence that suggests the movements in the dance correlate with the position of the flower, but there is other evidence that suggests they are irrelevant and the flower is found by a trail of pheromones.
In all other animals where this had been extensively studied (except orcas and maybe chimps), syntax has proven to be absent in natural calls, and also impossible to teach artificially. There are sometimes apparent breakthroughs, but it later turns out that the animal figured out a way to interpret "a", "b", "a then b", and "b then a" as four separate calls, without any deeper understanding. This is evident when you then teach it "c", and find out that it sees no difference between "c then a" and "a then c", and it takes just as long to teach it to distinguish these three calls; and then again just as long to teach it the difference between "b than c" and "c then b".
Have we tested each possible animal this way? No, of course not - but we have tested all the most likely candidates, and orcas and chimps were the only successes (and even here there is some debate). Crows, parrots, dogs, cats, gorillas, elephants, horses - none of these show any understanding of syntax.
