Is consonance attractive to budgerigars? No evidence from a place preference study

Area of Science:

• Auditory Perception
• Animal Behavior
• Bioacoustics

Background:

• Consonant intervals are common in harmonic sounds and animal vocalizations.
• Animals may perceive consonance as a signal of social stimuli.
• Previous studies suggest birds may be attracted to consonance, but experimental data is limited.

Purpose of the Study:

• To investigate budgerigar (Melopsittacus undulatus) attraction to consonant versus dissonant auditory intervals.
• To compare budgerigar responses to human responses regarding consonance preference.
• To explore the ecological relevance of consonance in auditory perception for animals with harmonic vocalizations.

Main Methods:

• Two experiments were conducted using a place preference paradigm.
• Experiment 1: Humans and budgerigars were exposed to consonant and dissonant piano melodies.
• Experiment 2: Budgerigars were exposed to consonant and dissonant chords derived from budgerigar vocalizations.

Main Results:

• Human females showed a preference for consonant stimuli, while human males did not.
• Neither male nor female budgerigars exhibited a preference for consonant over dissonant stimuli in either experiment.
• Budgerigar vocalizations arranged into consonant or dissonant chords also failed to elicit a preference.

Conclusions:

• The study did not find evidence that budgerigars are attracted to consonant auditory intervals.
• Results suggest that attraction to consonance may not be a universal trait among animals with harmonic vocalizations.
• Further research is needed to understand the role of consonance in animal auditory perception and vocal communication.
