Is Grammar Unique to Human Language?

While birdsong has long been known to share similarities with human language, the ability to convey different bits of information by simply rearranging word order was thought to be exclusively human.

This study revealed that Bengalese finches can learn grammar and, furthermore, that their grammatical abilities involve a specific part of the brain region distinct from other brain regions involved in singing. This is similar to what neuroscientists understand about human language processing.

If the tweets of birds can be roughly likened to strings of human words, and if bird brains process songs in a way similar to how human brains process language, future research may tackle whether these animals possess other cognitive abilities once thought to be singularly characteristic of human intelligence.

Strawberry Thief is one of William Morris’s most popular repeating designs for textiles. It takes as its subject the thrushes that Morris found stealing fruit in the kitchen garden of his countryside home, Kelmscott Manor, in Oxfordshire. To print the pattern Morris used the ancient and painstaking indigo-discharge method he admired above all forms of printing.
