Which navigational adjustment occurs with star visibility obscured?

💡 Explanation

When celestial cues diminish, migratory birds increase magnetic field alignment use, because magnetic inclination provides heading information when star-based celestial navigation is impossible; therefore, compass reliance increases, rather than olfactory maps alone because the compass provides a redundant long range directional cue.
