Abstract Restoring ecological dynamics is a key objective of conservation translocations. Exemplarily, reconnecting the reintroduced alpine populations with native Pyrenean through re‐establishing locally extinct in between, Causses and Pre‐Alps, major goal for long‐term Bearded Vultures Europe. Understanding Vultures' post‐release movements foraging behavior critical to understanding settlement newly restored supporting measures. The telemetric monitoring 43 translocated wild‐born juveniles allowed us investigate whether differences exist during first year life between populations. Medium‐ long‐distance exploration start spring following fledging both individuals. However, birds most distant release site (Causses) exhibited greater distances no clear directional movement pattern, had smaller home ranges, stronger preference supplementary feeding stations than those from other Although some Pre‐Alps displayed similar behaviors, pattern not as strong Causses, likely because proximity breeding Alps or number management stations. Preference (SFS) mostly occurred populations, but was lower Causses. Seasonal variations SFS were consistent among peak fledging. Beyond documenting Vultures, we suggest better accounting demographic consequences behaviors track translocation effectiveness, at local regional scales.
