Pre-recorded films featured moles, capercaillies and earwigs. Reintroductions have involved a facility for raising capercaillies in captivity at Sobrescobio. In this phase western capercaillies are most sensitive to disturbances. Western capercaillies are not elegant fliers due to their body weight and short, rounded wings. In Sweden, western capercaillies are the primary prey of the golden eagle ("Aquila chrysaetos").
