Which outcome occurs when a bird's syrinx asymmetries reduce?

💡 Explanation

When syrinx asymmetries decreases, vocalizations become homogenous because frequency variation relies on differential air pressures regulated by asymmetrical valves. This modifies song complexity; therefore, vocal range is reduced, rather than plumage or immunity adaptations altering.
