Song distinguishability predicts reproductive isolation between subspecies of the dark-eyed junco

This study examines song differences between dark-eyed junco subspecies and finds that more distinguishable songs correlate with reduced hybridization and greater genetic differentiation.

Ornament, armament, or toolkit? Modelling how population size drives the evolution of birdsong, a functional cultural trait

The paper models how population size influences the evolution of birdsong, showing larger populations improve song quality over time and predict song element loss during bottlenecks.

The role of early acoustic experience in song discrimination

This study shows that golden-crowned sparrow nestlings can discriminate between conspecific and heterospecific songs before song learning begins, and their responses are not influenced by prior exposure to heterospecific songs.
