✦ Synopsis

There is extensive diversity among the size of the song nuclei, and seasonal plasticity of the 4000 species of songbirds in different aspects of the song control circuits. In the second context, I dissong behavior, including the timing of vocal learning, sex patterns of song production, number of songs that cuss whether the vocal control systems of parrots and are learned (i.e., repertoire size), and seasonality of songbirds were inherited from a common ancestor or song behavior. This diversity provides unparalleled independently evolved. I also consider at what stage opportunities for comparative studies of the relationin the phylogeny of songbirds the hormone-sensitive ship between the structure and function of brain reforebrain circuit found in modern birds first evolved. gions and song behavior. The comparative approach I conclude by identifying directions for future rehas been used in two contexts: (a) to test hypotheses search in which a comparative approach would be about mechanisms of song control, and (b) to study productive. ᭧ 1997 John Wiley & Sons, Inc.
