Which outcome occurs when rapid wing beat frequency reduces avain air sac ventilation efficiency substantially during flight?

💡 Explanation

When high wing beat frequency impedes air sac ventilation, tidal volume decreases because the limited expansion-compression cycle reduces gas exchange, diminishing heat loss via evaporative cooling. Therefore, reduced heat dissipation will results, rather than enhanced uptake, buoyancy, or sensitivity, which need higher air sac efficiency.
