There is a degree of variation due to physical development, such as one observes in the young of the mute swan and the duck, whose voices change when maturity approaches, in much the same way as human voices change, becoming lower in pitch and altered in tone. During all this period of development, from helpless infancy to capable maturity, variations of vehemence, and the extraordinary excitement of certain of the emotions, are frequently inducing proportionately pronounced modifications of the voice. Later on occur those variations which are always traversed before the first complete songs are produced. In some instances the latter are, as I have shown (Chapter V.), mere repetitions of a call - note, displaying variations in pitch; but in many species, and especially in those popularly considered to be the best singers, songs are developed from exclamations of much wider range; in fact, the songs of m...
