The characteristic melody of a songbird is the product of its highly developed vocal organ, or song box, sometimes coupled with an elongated windpipe. Each species has its own set of songs and each bird performs its own version of those songs, varying the tone or pitch ever so slightly, so that his neighbors can identify the singer.

All vocalization by songbirds is a form of social communication, but not all songbird calls are considered “songs.” The songs as we recognize them are usually tunes used by males of the species in courtship and breeding, and in establishing and maintaining their territory. Females will sing on occasion and some species will even duet. Scientists think this may reinforce the bond of a mated pair.
