The fishing eagle, or osprey (Pandion haliaëtus), is the single one representing of the family of Pandionidae. It is the only diurnal bird of prey having reversible fingers and nostrils which can be closed, which enables him to better plunge under water to fish, the fish being its exclusive food.
Its overall length is 55 to 60 cm, its scale varies from 1,45 to 1,65 m and its weight is 1,1 to 2 kg. The lower part as of the its fingers is covered with plates corneas, in particular on the level of the articulations, which allows him, thanks to its long and hooked greenhouses, not to let escape its prey when this one is slipping.
The Osprey is widespread in Europe, in Asia, in Africa, in North America, in Central America and on the coasts of Australia. Under the moderated latitudes, this bird meets in the subtropics, it prefers the maritime coasts. In Corsica, the Ospreys, fishing eagles, at the edge of the extinction 15 years ago, have triple their manpower (approximately 20 couples) thanks to the efforts of protection of the Corsica regional natural reserve. They nest in cliffs of the littoral, and particularly in the natural reserve of Scandola. It is a solitary species, sometimes gregarious. The female lays, on average, three eggs; the small ones are nidicoles.
