The Eurasian Eagle-Owl is experiencing a sharp decline throughout Switzerland and in Ticino as well. In 1987–89, about ten occupied sites were identified between the Magadino Plain and the Riviera. The same census, repeated in 2013–2016, found only two breeding pairs. In Ticino, the presence of this nocturnal bird of prey is threatened by heavy human activity along the valley floors. A major cause of death for the species is collisions with power lines. In 2005, a young Ticino Eurasian Eagle-Owl was fitted with a satellite tracking device as part of a study by the University of Bern in collaboration with Ficedula; in 2006, two more juveniles were tagged; both of these died as a result of collisions. The protection of nesting cliffs is essential to its survival, along with the preservation of open areas that are indispensable for hunting.

Ficedula helped develop the Action Plan for the Eurasian Eagle-Owl for the Nature and Landscape Office of the Canton of Ticino.
