Adult Bengalese finches (Lonchura striata var. domestica) require real-time auditory feedback to produce normal song syntax.
The Bengalese finch is a close-ended learner that produces considerably variable songs as an adult; deafening adult finches resulted in development of abnormal song syntax in as little as 5 days; and there was considerable individual variation in the degree of song deterioration after deafening.
On-line Assessment of Statistical Learning by Event-related Potentials
The results suggest that the N400 effect indicates not only on-line word segmentation but also the degree of statistical learning, which is significant in high- and middle-learner groups.

It is hypothesize that mutations in the song control nuclei have occurred that enabled complex song syntax and became fixed into the population of domesticated Bengalese finches through a process of indirect sexual selection.
Twitter evolution: converging mechanisms in birdsong and human speech
Comparisons between different songbird species and humans point towards both general and species-specific principles of vocal learning and have identified common neural and molecular substrates, including the forkhead box P2 (FOXP2) gene.
Rhythmic synchronization tapping to an audio–visual metronome in budgerigars
It is suggested that vocal learning might have contributed to budgerigars' performance, which resembled that of humans, and showed evidence of entrainment to external stimuli over a wide range of tempos.

Stepwise acquisition of vocal combinatorial capacity in songbirds and human infants
A common, stepwise pattern of acquiring vocal transitions across species is found, suggesting that the long-noted gap between perceptual versus motor combinatorial capabilities in human infants may arise partly from the challenges in constructing new pairwise vocal transitions.

The usefulness of mouse “song” as a model of mammalian vocal learning is limited, but mouse song has the potential to be an indispensable model to study genetic mechanisms for vocal patterning and behavioral sequences.
Revisiting the syntactic abilities of non-human animals: natural vocalizations and artificial grammar learning
Evidence from spontaneously produced vocalizations as well as from perceptual experiments using artificial grammars to analyse animal syntactic abilities, i.e. abilities to produce and perceive patterns following abstract rules, confirms that animals can generalize and categorize vocal strings based on phonetic features.
