This study longitudinally tracks voice changes in aging zebra finches, finding that fundamental frequency and intensity are most sensitive to aging, with pronounced changes during the young adult to middle age transition.

This study identifies vocal biomarkers of aging and Parkinson's disease in zebra finches using acoustic analysis of song, revealing distinct patterns in spectral and intensity features between aging and disease states.

This study shows that overexpressing alpha-synuclein in zebra finch Area X reduces firing rates of specific neurons, mimicking Parkinsonian-like vocal impairments.
