Here’s a comprehensive overview of the Ural Owl (Strix uralensis), one of Europe’s most powerful and impressive forest owls. 🦉
🦉 Ural Owl (Strix uralensis)
Scientific name: Strix uralensis Pallas, 1771
Common name: Ural Owl
Family: Strigidae (True Owls)
Genus: Strix
🌍 General Overview
The Ural Owl is a large, pale grey-brown owl native to northern and eastern Europe and parts of Asia.
It is a non-migratory, resident species, occupying mature mixed and coniferous forests with open areas for hunting.
Strong and territorial, the Ural Owl is known for its fearless defense of nesting sites — even attacking intruders, including humans, if they approach too closely.

Length: | 50–62 cm |
Wingspan: | 110–134 cm |
Weight: | 500–1300 g (males smaller) |
Coloration: | Pale grey to brownish-grey, finely streaked with darker markings |
Facial disc: | Large, rounded, grey-white with darker rim — lacking ear tufts |
Eyes: | Dark brown (unlike yellow-eyed Tawny Owl) |
Bill: | Yellowish |

Sexes: | Similar in appearance, female larger |
🪶 Behavior and Vocalization
- Activity: Nocturnal, sometimes crepuscular (active at dawn/dusk).
- Call: Deep, far-carrying hooting — a series of rhythmic notes “hoo-hoo-hoo-hoo-hoo”, slower and more resonant than the Tawny Owl’s.
- Territory: Pairs occupy large territories year-round and defend them fiercely, especially during breeding season.
- Flight: Silent, buoyant, and purposeful; flies with steady wingbeats and long glides.
🌲 Habitat
- Prefers old-growth mixed or coniferous forests with clearings, forest edges, and nearby meadows for hunting.
- Often nests in tree cavities, old raptor nests, or nest boxes.
- Found from lowlands to mountain forests, avoiding treeless tundra and dense urban areas.
🍽️ Diet and Hunting
- Primarily small mammals, especially voles, mice, and shrews.
- Occasionally takes small birds, frogs, or insects.
- Hunts from a perch, swooping down silently on prey located by hearing.
- Plays a crucial ecological role as a rodent population regulator.
🪺 Breeding and Nesting
Aspect | Details |
---|---|
Breeding season: | March–June |
Nest site: | Tree hollow, old raptor nest, stump cavity, or large nest box |
Clutch size: | 2–5 eggs |
Incubation: | ~28–33 days, by female |
Fledging: | Young leave nest after 27–35 days but remain dependent for weeks |
Parental care: | Male provides food; female defends nest aggressively |
The female’s defensive behavior is famous — she will dive-bomb potential predators, sometimes striking people who approach nests.
🧭 Distribution
- Europe: Scandinavia, Finland, Baltic States, Poland, Czech Republic, Austria, Balkans, and parts of Central and Eastern Europe.
- Asia: Extends through Russia, Siberia, to northern Japan.
- Altitudinal range: Sea level to ~2000 m in mountain forests.
In Estonia, the Ural Owl is a resident breeder, most common in mature coniferous forests.
📉 Conservation Status
Category | Details |
---|---|
IUCN Red List: | Least Concern (LC) |
Population trend: | Stable or slightly increasing in many areas |
Main threats: | Loss of old-growth forests, reduction of nesting cavities, traffic collisions |
Conservation measures: | Nest box programs, forest management preserving large trees and snags |
