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.
Gray/Purple Heron
A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
