Similar to how human infants learn to speak, juvenile zebra finches learn to sing by memorizing and then matching their vocalizations to their tutor’s song (TS）during the developmental critical period. We previously identified a neuronal substrate of tutor song memories in the avian analog of secondary auditory cortex, the caudomedial nidopallium (NCM) (Yanagihara and Yazaki-Sugiyama, 2016). Recently, we found a transient projection into the song premotor area, HVC, from the NCM neurons which were specifically activated by hearing TS and by using activity-dependent viral expression of EGFP (AA
