Silbo Gomera - The Sweet Whistling Language That Transforms Humans Into Nightingales

If you ever visit La Gomera, one of the small islands that make up the Canaries, you are guaranteed to hear some sweet nightingale like whistling sounds. While some may emanate from the golden-voiced bird itself, chances are most of what you are hearing is coming from the residents, who believe it or not, are tweeting actual words to each other in a language they call Silbo Gomera (Spanish for 'Gomeran Whistle') or El Silbo (the whistle).
