Songs of wild birds tell an ecological story to Glen Ellen soundscape ecologist Bernie Krause.

The reason we’re standing in the dark 1,300 feet up in the mountains next to burbling Sonoma Creek is because we’re with Bernie Krause, a globe-trotting Glen Ellen audio specialist who has a passion for capturing the secret sounds of animal life. We’re hoping to hear something special: the dawn chorus, the waking cacophony of wild birds on a spring morning.
