The Eurasian Eagle-Owl is one of the largest owls in the world, a powerful nocturnal predator with a barrel-chested body, prominent ear tufts and glowing orange eyes. Found across a huge swathe of Europe and Asia, it hunts a remarkable range of prey and sits at the top of the food chain in many of the rocky, wooded and open landscapes it occupies. Its deep, far-carrying hoot is one of the most evocative sounds of the northern night.
Despite its size and adaptability, the Eagle-Owl can be surprisingly hard to see, spending the day roosting motionless on a cliff ledge or in dense cover. Persecuted and reduced in parts of Europe during the twentieth century, it has recovered in many areas thanks to protection and reintroduction, and is now assessed as Least Concern across its vast range, though local populations can still be sensitive to disturbance and human pressures.
Sheer size is the first clue: this is a massive owl with a bulky body, broad wings and a wingspan approaching two metres. Combined with the mottled tawny-brown plumage, long ear tufts and large orange eyes, it is hard to mistake for any other owl across most of its range.
| Size | Very large owl, 58-75 cm long with a wingspan of 1.6-1.9 m |
| Eyes | Large and bright orange |
| Ear tufts | Long, prominent feather tufts on the head |
| Plumage | Mottled tawny-brown, streaked darker, with a paler streaked underside |
| Build | Barrel-chested and powerful, with heavily feathered legs and strong talons |
| Flight | Direct and powerful on broad wings, often low over the ground |
The male's song is a deep, resonant two-note hoot, often written as oo-hu, that carries for several kilometres on still nights and is used to advertise territory. Females give a slightly higher and hoarser version, and pairs may duet. Around the nest the birds also produce a variety of barks, growls and shrieks, particularly when defending eggs or young.
The Eurasian Eagle-Owl ranges widely across Europe, the Middle East, Central Asia, Russia and much of Asia, occupying an enormous variety of habitats. It favours rocky country, cliffs, gorges and quarries with nearby open ground for hunting, but also uses forests, steppe, semi-desert and even the edges of towns. This flexibility in habitat is a large part of why it is so widespread.
This owl is a formidable and versatile hunter, taking mammals and birds ranging from voles and rats up to hares, rabbits and even young foxes or roe deer fawns, along with birds as large as ducks, crows and other raptors. It also eats reptiles, amphibians, fish and large insects when available. Prey is usually caught in a swift attack from a perch or in low flight and carried off in the talons.
Eurasian Eagle-Owls nest early in the year, typically on a sheltered cliff ledge, in a rock crevice, among boulders or occasionally in an old nest of another large bird or on the ground. The female usually lays two to four eggs and does the incubating while the male brings food. The young leave the nest before they can fly properly, clambering about nearby, and remain dependent on their parents for some months.
- Great Horned Owl: The North American counterpart, similar in shape with ear tufts but smaller and greyer
- Snowy Owl: A large northern owl in the same genus but white and lacking ear tufts
- Long-eared Owl: A much smaller owl with long ear tufts and orange eyes that can suggest a miniature eagle-owl
