Which consequence results when white-crowned sparrow chicks are isolated from tutor songs during early sensitive periods?

💡 Explanation

Abnormal song structure occurs because lack of exposure prevents proper imitation via vocal learning, meaning no template. This interferes with the birdsong development mechanism; therefore aberrant songs are produced, rather than expected species-specific sounds.
