To sample the incredible variety and diversity of bird vocalization, visit www.birds.cornell.edu/home /. “Cornell Lab of Ornithology is a great resource for audio of the songs,” suggests Dr. Michael Bender, program director, NIGMS Division of Genetics and Molecular, Cellular and Developmental Biology (and NIH Record bird photographer). “Just search by species name and click on the audio button on the species account.”
