Which cue diminishes during noctural songbird's celestial migration?

💡 Explanation

Disrupted star field tracking decreases the perception of their azimuthal rotation, because the celestial compass depends on continuous recalibration; therefore, orientation ability is impaired, rather than other sensory inputs which might remain consistent.
