Which outcome predominantly results when birds lose barbules cohesion within primary flight feathers?

💡 Explanation

When barbule cohesion is lost, the feather's vane loses its integrity; airflow through the feather increases because air passes through gaps resulting from disrupted van structure, therefore lift to declines. Increased lift reduction efficiency results, rather than insulation, predation or susceptibility, which involve skin contact or external organisms.
