Which homing behavior arises when migratory birds encounter overcast conditions?

💡 Explanation

Restricted celestial navigation causes errors; therefore, a magnetic compass orientation mechanism helps them maintain direction, because this allows course correction, rather than random flight; reliance upon the stars alone fails under heavy cloud.
