Temporal variability enhances the acquisition of stereotyped communication signals

This study shows that deviations from stereotyped syllable sequences and timing in zebra finches do not reduce vocal learning and can even enhance it in later-developing birds.

Fidelity of and biases in the developmental acquisition of song tempo in a songbird

This study examines how biological predispositions and developmental experiences shape the tempo of birdsong in zebra finches, finding high fidelity in gap duration imitation and biases in stereotypy.

Introductory gestures before songbird vocal displays are shaped by learning and biological predispositions

This study shows that introductory notes in songbirds are shaped by both learning and biological predispositions, with experimental evidence from zebra finches.

Behavioural responses to video and live presentations of females reveal a dissociation between performance and motivational aspects of birdsong

The paper examines how male zebra finches respond to live and video presentations of females, finding dissociation between song motivation and performance.
