Balearic and Cinderella shearwaters of the Mediterranean are increasing! The analysis of the migration counts made by the Migres Foundation, in collaboration with “Instituto de Estudio Ceutíes”, shows us that the breeding population of these two species has grown during the last ten years . This growth is more remarkable in the Balearic Shearwater. These and other results of the project were communicated at the last International Congress on Migration and Global Change.
