COVER A young zebra finch (left) attending to his father (right). During development, juvenile birds listen to and imitate their father's courtship song. Through behavioral tracking and synaptic current measurements, Vallentin et al. show that neuronal circuit inhibition preferentially targets specific pieces of song that the birds have already mastered, suggesting a new circuit mechanism for observational learning. See page 267.
