Summary: "We investigated the distribution of Greater Spotted Eagle wintering grounds in the Mediterranean Basin on the basis of telemetry data from individuals caught in breeding grounds, detailed species counts during wintering in Greece, and a literature search. We found that at least 300–400 individuals (c.15% of the European population) winter in the Mediterranean Basin, sometimes numbering a few dozen in particular river valleys. Individuals used on average 89.7 km2 home ranges for wintering. "

Discussion: "Single birds may winter on islands, such as Crete, where they probably primarily scavenge on dead goats and sheep (Maciorowski, pers. obs.). Scavenging behaviour may be underestimated in this species, especially in juveniles, as in the case of Spanish Imperial Eagle Aquila adalberti (Margalida et al. Reference Margalida, Colomeer, Sánchez, Sánchez, Oria and González2017)."
