For the first time, more than 65,000 sound clips and approximately 18,000 video clips of birds and other animals are accessible at no charge at the Cornell Lab of Ornithology Macauley Library Web site, The Cornell Lab formerly shared these remarkable sounds through audio guides. Although the collection has a North American emphasis, it includes a generous sampling from around the world. Visitors can listen to birds while watching a real-time spectrogram and waveform scroll. This feature, called Raven Viewer, is the first and only player that allows real-time visualization of sounds on the Internet. The player recently won a prize in Science magazine's "Science and Engineering Visualization Challenge," which recognizes outstanding achievement in using visual media to promote understanding of scientific phenomena.
