Which risk increases when a seabird's plumage loses water-repellent properties?

💡 Explanation

When plumage loses water-repellent properties, increased water absorption occurs altering buoyancy regulated by feather microstructure because air is displaced, leading to increased overall bird mass and decreased ability to float. Therefore decreased buoyancy results, rather than maneuverability, radiation protection or efficiency, which are functions of flight control, pigmentation, and airfoil shape.
