The genetic diversity and population structure of the Lesser Kestrel (Falco naumanni), a threatened migratory falcon, were assessed to inform conservation strategies under the LIFE project for the species' reinforcement in Bulgaria, by means of neutral microsatellite markers and non-neutral candidate gene markers associated with migratory behavior. The Core European populations (Spain, Italy, Greece) exhibit high genetic diversity and low differentiation, making them suitable sources for conservation translocations. In contrast, peripheral populations (e.g., Mongolia, Limnos Island) are genetically distinct and less suited for reinforcement due to potential risks of outbreeding depression. Non-neutral markers showed minimal genetic differentiation among populations, suggesting a lack of disruptive adaptive divergence within the species' range. These findings emphasize the importance of genetic similarity and diversity in translocation strategies and highlight the potential for maintaining adaptive potential while avoiding maladaptive outcomes. This integrated approach offers a framework for enhancing the genetic resilience and long-term stability of Lesser Kestrel populations in Bulgaria.
