They're called "bird-watchers," but many birders, both amateurs and professionals alike, never actually
see the feathered species they're tracking. Instead, they identify and study birds by listening carefully to
their songs and calls. Join producers John Keefe and Joe Shepherd as they go bird-listening with folks
who keep an ear on declining bird populations. They hear the changes in avian habits and habitats, and
even play recorded songs over speakers to call birds back to areas they've abandoned.
