Common Buzzards wintering strategies as an effect of weather conditions and geographic barriers
Abstract Aim Migration is a constantly changing adaptation due to the climate condition evolution. The struggle for surviving during harsh winter season is different across Europe, being more complex toward the inner parts of the continent. The current approach explores the Common Buzzard number var...

While the high number of individuals in Moldova is related to their eastern and northeastern Europe origins, in Transylvania the large number of individuals observed is related to the more sheltered characteristics of the region attracting individuals from central Europe.

From this point of view, we can consider that the Carpathian Mountains are a geographic barrier for wintering birds of prey.
