In the video from Youtube below, there the narrator speaks using Gomeran whistle [wiki] and tells us some of the charasteristics of La Gomera. I've transcribed the whole text and translated it into English for you. If you're a good Spanish speaker you can figure out some of the words from the whistles because they only replace the sounds with whistles to allow speaking from far away:
Spanish:

Funny thing... Our pet canary is usually pretty active this time of day, singing & flying around his cage, but while that video was playing, he sat on his perch listening intently. Now that it's done he's singing up a storm & flying back & forth like mad! He's got to be several generations removed from the islands, but the sound must mean something to him. When we whistle to him, he just ignores us.
