High Quality Content by WIKIPEDIA articles! Eleonora's Falcon (Falco eleonorae) is a medium- sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis. The Sooty Falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species. Eleonora's Falcon is named after Eleonor of Arborea, national heroine of Sardinia. This species breeds on islands in the Mediterranean particularly off Greece (where two-thirds of the world's population breeds), but also in the Canary Islands, and off Spain, Italy, Croatia, Morocco and Algeria. Tilos Park is the breeding area for ten percent of the world population of Eleonora Falcons. Six hundred and fifty pairs of this species breed on this island according to research conducted by the Hellenic Ornithological Society and the European Union LIFE- Nature program of Tilos. It is rare as a vagrant north of its range.
