Which risk increases when avian feathers experience excessive preening, altering barb alignment?

A)Reduced flight control at high speeds✓

B)Increased heat loss at low temperatures

C)Elevated UV radiation penetration risk

D)Decreased buoyancy during foraging swims

💡 Explanation

When feathers are excessively preened, causing barb misalignment, aerodynamic efficiency is reduced because the interlocking structure is disrupted, impacting lift generation and control especially during complex maneuvers. Therefore flight control reduction results, rather than increased heatloss, UV penetration, or buoyancy loss, which relate to insulation or floatation functions.
