The association between an embryo’s sound discrimination score (change in heart rate beats/min during dishabituation trial) and its observed song complexity (number of song elements) as a fledgling. Data are shown for 18 field nests (12 unmanipulated nests with genetic parents, 6 cross-fostered nests with foster parents) for which we have prenatal sound discrimination score and song recordings of both parents and fledglings recorded 7–8 weeks after leaving the nest. Fledglings acquired more song elements if they had stronger sound discrimination (negative value = strong response) as embryos
