Frequency discrimination in budgerigars (Melopsittacus undulatus): Effects of tone duration and tonal context
2000
Journal of the Acoustical Society of America
Studies of frequency resolving power in budgerigars ͑Melopsittacus undulatus͒ have shown that this species has excellent discrimination abilities for both simple and complex sounds falling in the region of 2 to 4 kHz-the frequency range of their contact call. In four experiments, frequency discrimination by budgerigars of short tones similar to elements found in the contact call was examined. Frequency difference limens ͑FDLs͒ for simple pure tones at 2.86 kHz were constant for tone durations
