Supplementary Materials

The PDF file includes:

  • Supplementary Texts 1 and 2
  • Fig. S1. Boxplot of average δ2Hf in body coverts/scapulars of ortolan buntings captured during the breeding season by country where birds were captured (birds captured in Israel and Kuwait were spring migrants).
  • Fig. S2. Genetic assignment of breeding individuals to the eastern, western, and northern clusters following cross-validation.
  • Fig. S3. Genetic assignment of individuals sampled during migration along the eastern and western flyways to a breeding population.
  • Fig. S4. Genetic assignment of individuals sampled during migration in France (western flyway) to a breeding population other than the eastern cluster (as stable isotopes and archival light loggers excluded an eastern breeding origin for western migrants).
  • Fig. S5. 100-year extinction probability for various demographic and hunting scenarios.
  • Table S1. Number of geolocators deployed and retrieved by country (region) and year when data were retrieved from the logger and logger model.
  • Table S2. Summary of base demographic parameters values for Vortex population viability analysis
  • Table S3. Best model structures for survival analyses.
