It's amazing how many fascinating creatures live all around us, yet we are often times too busy or distracted to notice them. For instance, the Great Horned Owl, North America's greatest predator, lives right in our neighborhood trees. Take an evening walk with me and let's listen for owls, the most mysterious yet human like of birds. A special thank you to the musicians and sound artists who contribute to the sound of Big Blue Planet: David Arkenstone, "Yosemite," Mannheim Steamroller,"Eagles," "Wolves," Himekami, "Maharobi," S. Nardell and G. Bodossian, "Nota Bene." Sounds of Great Horned Owl, Western Screech Owl, Elf Owl, Northern Pygmy Owl and Great Gray Owl courtesy of Lang Elliot.
