Question

Quizplus · Accepted Answer

Male white-crowned sparrows reared in isolation and exposed to recordings of their species-specific song before 2 months of age can produce the species-specific song as adults. However, for the song to be fully developed, they need to hear the songs of conspecifics during their first breeding season. Therefore, the male that is reared in isolation and exposed to recordings of his species-specific song before 2 months of age, and who hears the songs of conspecifics during his first breeding season, is most likely to produce the species-specific song as an adult.
