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.

Golden Eagle

Among the most powerful and widely distributed raptors in the world, golden eagles have wingspans reaching 2.2 meters and inhabit mountainous terrain across the Northern Hemisphere. Supreme aerial hunters, they use soaring flight and steep dives at speeds over 200 km/h to capture rabbits, hares, ground squirrels, and occasionally young deer and foxes. In many cultures they have been central to falconry traditions spanning millennia.
