The authors of an article published in the journal Raptor Journal tracked a juvenile greater spotted eagle west of the Ural Mountains between 2018 and 2020. A summary of the key findings is presented in the table below.

Most greater spotted eagles that spend the summer west of the approximately 42°E meridian overwinter in southern Europe, the Asian part of Turkey, the Levant, and Africa. Conversely, individuals that spend the summer east of this meridian overwinter in southern Asia, including on the Arabian Peninsula.
