Which outcome results when a songbird's syrinx is constrained?

💡 Explanation

A restricted syrinx limits the vocal cord's physical freedom to rapidly adjust tension. The resulting decrease in vocal frequency modulation is because rapid musclar motion is physically prevented, therefore vocal range reduces rather than another systematic failure occurring.
