Which consequence results when a songbird population loses vocal range?

💡 Explanation

Losing vocal range degrades song complexity thereby affecting mate attraction success because complex songs are the primary signal for evaluating male quality in many bird species and impaired vocalization diminishes this selection; therefore, mate attraction is weakened rather than other effects under the specialized mating communication system.
