Which reduction affects a bird’s flight when feather barbules unlock?

💡 Explanation

A loss of cohesion results in aerodynamic deficiency because the feather's airfoil shape is disrupted by a change called the feather's barbule interlocking mechanism. This decreases lift; therefore, flight efficiency is impaired, rather than changes in bone density or plumage.
