Recall the Experiments of Peter Marler

question 147

Multiple Choice

Recall the experiments of Peter Marler. If a male white-crowned sparrow only hears (during his sensitive period) a recording of a male of the same species singing, how will this affect his ability to sing?

• A)This bird will be unable to sing his species' song, as white-crowned sparrows are taught this song by females of the same species.
• B)This bird will still be able to sing a perfect rendition of the white-crowned sparrow song, as this song is the result of genetic programming (and is not "taught").
• C)This bird will be unable to sing his species' song, as white-crowned sparrows can only learn their species' song by listening to a live member of the same species.
• D)This bird will still be able to sing the white-crowned sparrow song, as he can learn this song from the recording.
• E)This bird will be unable to sing the white-crowned sparrow song, as these birds go deaf if they are not exposed to live-sung songs during the sensitive period.
