Which phenomenon reduces long-distance soaring efficiency when a bird's wing loading is excessively high?

💡 Explanation

When wing loading becomes high, a bird must generate increased lift at lower airspeeds, leading to stronger wingtip vortices due to Bernoulli's principle and increased induced drag. Thus, increased induced drag results, rather than others as hypoxia requires respiratory compromise, wear requires abrasive contact, and fatigue results from sustained muscle exertion.
