If atmospheric haze obscures the setting sun during migration, which consequence results for some bird species?

💡 Explanation

Migration relies on a celestial compass; if haze obscures the sun, calibration of navigation via stellar cues is impaired, because the birds cannot correctly orient themselves using the sun’s position. Therefore, celestial compass calibration gets affected, rather than reliance on weather or landmarks.
