In a remote mountain village high above Turkey's Black Sea coast, there are villagers who still communicate across valleys by whistling. Not just whistling as in a non-verbal, "Hey, you!" But actually using what they call their "bird language," Turkish words expressed as a series of piercing whistles.
The village is Kuskoy, and it's inhabited by farmers who raise tea, corn, beets and other crops, and also keep livestock. The landscape is unusual by Turkish standards, and the residents are also considered a bit eccentric by other Turks.
