Abstract The physical characteristics of vocalization were examined in budgerigars (Melopsittacus undulatus) deafened at the age of about 28 days. Autocorrelation was used in the analysis, with 2 parameters: 1) inter-element intervals and 2) amplitudes of all sound elements of the vocalization. The deafened birds developed the temporal pattern specific to normal warble song in autocorrelograms. However, abnormalities were found in the frequency spectrum of elements. The temporal pattern of warble song might be an innate character, because auditory feedback is unnecessary for its development.
