Whistled language In the Turkish province of Giresun, the locals in the village of Kuşköy have communicated using a whistled version of Turkish for over 400 years. The region consists of a series of deep valleys and the unusual mode of communication allows for conversation over distances of up to 5 kilometres. Turkish authorities estimate that there are still around 10,000 people using the whistled language. However, in 2011 UNESCO found whistling Turkish to be a dying language and included it in its intangible cultural heritage list. Since then the local education directorate has introduced it as a course in schools in the region, hoping to revive its use. A study was conducted by a German scientist of Turkish origin Onur Güntürkün at Ruhr University, observing 31 "speakers" of ("bird's tongue") from Kuşköy, and he found that the whistled language mirrored the lexical and syntactical structure of Turkish language.
