A new paper from Medraptors is just out now. The article compares the spring and fall migration of Short-toed Snake Eagles at the Apuan Alps and in a new watchpoint in Greece, the Mount Olympus. The results of this research show that also the Greek population of this species makes a long detour to avoid crossing the Mediterranean, via Bosphorus, both in autumn and in spring. In the article are analyzed and discussed differences in the percentages of juveniles migrating together with adults in the autumn at both sites. These results are put in relation with the width of ecological barriers in the study area, assuming that a relationship exists between the size of the stretch of sea that divides Europe from Africa and the tendency of juveniles to follow the adults during their first migration.
