Every few years a headline announces that some animal "has language". The truth is more interesting than the hype, and it starts with a dancing bee.
The waggle dance
In the 1920s, the Austrian zoologist Karl von Frisch noticed that honeybees returning from a good flower perform a special dance that tells other bees where the food is. The work helped earn him a share of the 1973 Nobel Prize in Physiology or Medicine. A bee, in other words, can describe a location to someone who was not there. That is a big deal.
Birds with grammar
More recently, researchers studied Japanese great tits, small birds with more than ten different notes in their calls. One combination means roughly "scan for danger", another means "come here". Played together in the usual order, birds do both. But when scientists artificially reversed the order, the birds rarely responded. The 2016 paper in Nature Communications called this the first experimental evidence of compositional syntax in a wild animal.
So, do they have language?
It depends on your definition. Animals clearly communicate, and some combine signals by rules. What nobody has shown is an animal system with the open-ended creativity of human language, where a finite set of words can express an unlimited number of new ideas.
That difference is worth pointing out to a Year 10 class wrestling with word order in French. When they put adjectives in the wrong place, they are breaking the kind of rule a tit would notice. The good news is that they can also say things no bird ever will.
