Barb Structure

Extremely soft, plumulaceous towards the base and velvety pennaceous towards the tip, featuring specialized velvety pile and velvety barbules that eliminate flight noise.

Geographic Range

Palearctic ecozone, widespread across Europe, Asia, and parts of the Middle East, with resident populations throughout its range.

Ecological Role

Apex nocturnal raptor regulating populations of medium-to-large mammals and birds, serving as an important indicator of ecosystem health.

Similar Species

Long-eared Owl (Asio otus) and Short-eared Owl (Asio flammeus), though their feathers are significantly smaller and differ in baring patterns.
