Résumé :	Ospreys have been thoroughly monitored in Corsica since 1977, when a study on their nesting ecology was started. In this paper, we summarise actions, both research and conservation, which took place between 1977 and 1997. We focus on the past and present distribution of the species on the Island, particularly with regard to its constant, but slow, increase. The increase in Corsica was not identical to increases that occurred in other areas in Europe and North America. The original area may have been saturated by 1990, because from 1990 to 1997, c. 10 pairs colonised former breeding sites that were left unoccupied for 20-30 years, mainly in the north of Corsica. All colonising pairs used artificial platforms with decoys. Research on Ospreys in Corsica covered behavioral aspects, diet and movements, and is currently dealing with behavioural ecology, mating and competiton for nests.
