Social performance reveals unexpected vocal competency in young songbirds.

ABSTRACT: Vocal ontogeny in songbirds provides a good model for understanding how complex motor behavior, including speech, is learned. For birdsong, as for other motor learning, it has generally been assumed that a subject's motor output at any point during learning represents what the subject has learned to produce by that time. Here, we show, however, that juvenile zebra finches partway through song learning, singing immature song, are capable of producing song with much more mature properties, depending on the behavioral context. In these birds, we were able to elicit courtship (female-directed) song, which young birds normally sing infrequently, and to compare it with the alone or "undirected" song (Undir) predominantly produced during learning as well as with the same bird's subsequent adult s
