Why it matters 🌍
Understanding variation in phenological plasticity can help predict which species can keep pace with rapid climate change.

Key findings 🔍
• Long-distance migrants = less plastic
• Populations in warmer, more predictable, or faster-warming sites = more plastic

➡️ Both local climate + life-history traits shape phenological plasticity.

📊We analysed 40+ years of bird monitoring data across Europe to ask what explains differences in phenological plasticity across and within 50 songbird species.

🔍 Key insights:

✅ The proportion of juveniles over time can provide reliable estimates of mean laying dates and reproductive success.

✅ Multi-site analyses suggest that 4–5 sampling sessions per season offer a good balance between effort and accuracy.
