is the largest owl living (may weigh up to 3 kg with wingspan up to 170 cm). The silhouette of sitting eagle owl is hardly mistakable, for it has movable distinctive ear tufts of feathers on its head. It likes to settle on rocky hillsides, ruins with forests in the vicinity, but also uses tree cavities or desolate raptors' nests. Eagle owl is a solitary nocturnal creature. It predominantly hunts rodents and other small mammals, but also small birds. Eagle owl attains maturity at the age of 2 – 3 years and has a lifespan of up to 60 years. It is an endangered species.
