European honey buzzard
Migratory birds with a low wing loading, such as stork, European honey buzzard, black kite, marsh harrier, kestrel, and hobby, depend on thermals and updrafts for soaring to cross the Mediterranean in spring. Although the majority of these birds enter Europe via the Bosphorus or Straits of Gibraltar, large numbers leave at Cap Bon in Tunisia and enter Europe via the Aeolian Islands and the Straits of Messina to Calabria. Most of these birds breed in central and northern Europe. The birds return to Africa in autumn by the same route.
