Greece is located at the southernmost end of the Balkan Peninsula and the shortest distance between Greece and north Africa is roughly 280 km. As raptors mostly fly over land exploiting thermal currents, the ecological barrier shaped by the Mediterranean Sea south of Greece, has a strong impact on the migration strategy adopted by each species. Using data from recent studies at three watchsites in Greece (island of Antikythira, Mount Olympus, National Park of Dadia-Lefkimi-Soufli) we discuss the migratory behaviour of some selected species. The three commonest species were the Eurasian marsh harrier Circus aeruginosus, the western honey buzzard Pernis apivorus and the short-toed snake eagle Circaetus gallicus. The first migrates on a broad front over the sea. A similar migration strategy is adopted also by the Eleonora's falcon Falco eleonorae. The western honey buzzard performs a loop migration strategy concentrating over the island of Antikythira in autumn but bypassing it in spring. The short-toed snake eagle, on the other hand, avoids the crossing of the Mediterranean Sea performing a long detour and crosses the sea at the Bosphorus. Observations suggest that the levant sparrowhawk Accipiter brevipes and the lesser spotted eagle Aquila pomarina adopt a similar strategy. Finally, species such as the common buzzard Buteo buteo and the sparrowhawk Accipiter nisus do not cross the Mediterranean Sea but move across Greece to winter in southern Greece. © 2013 CISO - Centro Italiano Studi Ornitologici.

The aim of this study was to describe the phenology of migration, biometrics and fat storage of the Red-breasted Flycatcher Ficedula parva in Greece, based on mist-netting studies on Antikythira Island. The data suggest that autumn passage takes place between early September and late October. Most birds that arrived on the island were carrying moderate fat reserves and only paused on Antikythira between nocturnal flights. © 2011 British Trust for Ornithology. Source

We document the first systematic survey of the spring and autumn migration of raptors along the central-eastern Mediterranean flyway, from observations on Antikythira, in southern Greece. More raptors were observed in autumn than in spring, mainly due to the much greater autumn passage of adult Honey-buzzards Pernis apivorus. Results suggest that the entire Greek population of Black Kites Milvus migrans uses this flyway. Our observations of Short-toed Eagles Circaetus gallicus suggest that adults breeding in southern and central Greece avoid Antikythira and follow a circuitous migration via the Bosporus or Dardanelles, while some juveniles in autumn appear to attempt a sea crossing via Crete to Libya. © British Birds 104.

In this study, we examined the spring migration phenology and arrival body mass and fat score of two long-distance migrants, the Eastern Bonelli's Warbler Phylloscopus orientalis and the Semi-collared Flycatcher Ficedula semitorquata at a small Greek island. Our data indicate a regular and early spring passage of both species through the area, with the Semi-collared Flycatcher peaking in late March and early April and the Eastern Bonelli's Warbler about a week later. The arrival body masses of both species were lower than any other mean value of body mass previously reported. This, along with the low fat loads of both species, indicates that the birds' reserves are depleted after crossing the Mediterranean Sea and suggests that they had probably not refuelled after the desert crossing. © 2013 Copyright British Trust for Ornithology.

This study provides the first systematic survey of spring and autumn migration of adult European Honey Buzzards (Pernis apivorus) along the Central-Eastern Mediterranean flyway. Observations were done in 2007 and 2008 over the island of Antikythira (southern Greece), located 33 km NW of Crete. A total of 135 birds were counted during spring, 101 in 2007 and 34 in 2008. During post-reproductive movements, the passage of 2479 individuals was reported, 1131 in 2007 and 1348 in 2008. During both years an evident peak during the last ten-days of August occurred. These results clearly show differential spring and autumn migration of adult European Honey Buzzards through this region. Historical data concerning prevailing winds were used to reconstruct general wind patterns in the Central-Eastern Mediterranean region. It showed north-northwesterly winds between southern Greece and Libya during both spring and autumn, but very weak (&10 km/h) during the first period. We discuss two hypotheses to explain why the spring visible migration was so scarce: 1) a narrow migratory loop, with the European Honey Buzzards using a direct path between Libya and Peloponnesus during spring, bypassing Antikythira, and 2) a loop migration on a greater scale, involving a detour via the Bosphorus/Dardanelles' Strait and/or the Central Mediterranean, that would allow the European Honey Buzzards to minimise the water crossing but increasing the overall migration distance. In the light of previous studies on this species, the first hypothesis seems to be much more reliable than the second one. © 2012 Copyright 2012 Unione Zoologica Italiana. Source
