Eurasian Eagle-Owl

The world's largest owl species by height and weight, Eurasian eagle-owls have wingspans up to 1.9 meters and inhabit rocky landscapes, forest edges, and cliffs from Europe across Asia to China. Silent nocturnal hunters with powerful talons, they prey on rabbits, hares, foxes, and even other raptors. Their deep, resonant hooting carries over great distances. Relatively stable in population, though persecuted historically.
