Birdsongs are used extensively as models for animal signaling and human speech, offering a glimpse of how our own communicating abilities developed.

Even bird brains can get to know an entire continent -- but it takes them a year of migration to do so, suggests a Princeton research team.

Neuroscientists are attempting to understand if structural changes in the brain are related to sensory experience or the performance of learned behavior, and now University of Washington researchers have found evidence that one species of songbird apparently has something in common with a few baseball sluggers.

When it's time to mate, female white-crowned sparrows are looking for a male who sings the latest version of the love song, not some 1979 relic.

Long before the National Security Agency began eavesdropping on the phone calls of Americans, young song sparrows were listening to and learning the tunes sung by their neighbors.
