Quantifying the non-breeding provenance of staging Ruffs, Philomachus pugnax , using stable isotope analysis of different tissues
International conservation efforts for migratory populations are most effectively based on quantification of the geographical linkages between wintering, staging, and breeding areas, patterns that may not remain constant in times of global change. We used stable isotope (δ 13C, δ 15N, and δ 2H) meas...

International conservation efforts for migratory populations are most effectively based on quantification of the geographical linkages between wintering, staging, and breeding areas, patterns that may not remain constant in times of global change. We used stable isotope (δ 13C, δ 15N, and δ 2H) measurements of different tissues representing distinct periods of dietary integration to quantify the non-breeding provenance of a threatened staging population of Ruffs Philomachus pugnax. In 199 staging Ruffs captured in 2012 during northward migration in the Netherlands, we compared the multi-isotope patterns of feathers grown at wintering grounds, with the δ 13C and δ 15N profiles of blood cells and plasma representative of staging areas.
