Ecological Transition and the communities agreed on a pilot project to release specimens of the eagle, the largest raptor in Europe. 25 specimens were released, 21 of which are still flying in the area.

After criticism from some biologists and ecologists, Cantabria and Asturias have now paralyzed the initiative, leaving these 21 huge birds in a complex administrative limbo. The Ministry for the Ecological Transition, which considers this raptor extinct in Spain, promoted in 2021 a project to reintroduce eagles – brought from Norway.
