Description

A classic raptor tail feather displaying striking dark brown and pale barring. The Eurasian Sparrowhawk is a small, agile ambush predator with short rounded wings and a long tail designed for high-speed woodland navigation.

Colour & Pattern

Rich chocolate-brown or slate-grey base with distinct, evenly spaced pale greyish-white or buff transverse bars across both vanes, creating a classic raptor tail-banding pattern.

Barb Structure

Tightly interlocked pennaceous structure with strong barbs and barbules featuring functional hooklets, providing aerodynamic stability. No prominent afterfeather.

Texture & Surface

Smooth, firm, and matte in appearance with a stiff, resilient vane designed to withstand high winds and friction during flight maneuvers.

Key Features

Distinct alternating dark brown and pale greyish-white transverse bars, elongated symmetrical shape, and stiff pennaceous barbs characteristic of an Accipiter rectrix.

Habitat

Woodlands, forests, forest edges, agricultural land with scattered trees, parks, and suburban gardens.

Geographic Range

Widespread across temperate and subtropical parts of the Palearctic realm, including Europe, Asia, and parts of North Africa.

Ecological Role

Acts as an apex avian predator in woodland ecosystems, helping to regulate small bird populations and maintain ecological balance.

Similar Species

Eurasian Kestrel (Falco tinnunculus) or Cooper's Hawk (Accipiter cooperii), though distinguished by specific bar width, proportions, and geographic distribution.

Interesting Facts

Female Eurasian Sparrowhawks are significantly larger than males—a classic case of reverse sexual size dimorphism in raptors, allowing them to hunt larger prey.

Condition Notes

Good condition with intact barbs and minimal fraying at the tip, showing a healthy, fully grown feather.
