You are told that the song of males among a particular songbird species has an innate component but is also largely learned. Nestling males imprint on their father's song and then sing it themselves when they reach sexual maturity. Which of the following observations would lead you to doubt this information? A) A male chick reared in isolation but introduced as an older juvenile into an aviary containing normal males of his species sings his species' song.

B) A male chick who is reared in isolation but hears tape recordings of his species' song grows up to sing normally.

C) A male chick who is reared in isolation but hears tape recordings of a different species' song grows up to sing that species' song.

D) A male chick fostered in the nest of a different species grows up to sing the song of its foster species.
