Question

Quizplus · Accepted Answer

Exposure to the species-typical song before 2 months of age is important for learning the song. However, exposure to conspecifics during the first breeding season is also necessary for refining and ultimately producing the correct song. Therefore, a male raised in isolation, exposed to tapes of white-crowned sparrow song before 2 months of age, and exposed to the singing of other white-crowned sparrow males during its first breeding season is the best choice for singing the correct species-typical song in adulthood.
