Which consequence occurs when a bird's wings experience increased span loading?

💡 Explanation

Elevated span loading concentrates aerodynamic forces, thus promoting greater feather abrasion due to friction causing increased structural failure risk, because induced stress accumulates at connection points. Therefore, structural failure risk elevation is promoted, rather than improved soaring behavior or efficiency.
