Which process causes seasonal migration timing shifts given changing daylight?

💡 Explanation

Photoperiodism dictates hormonal shifts governing bird migration preparation because changing day length stimulates endocrine responses. Consequently, migration onset aligns with optimal environmental conditions, rather than being static or triggered by temperature primarily.
