Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Accipitriformes; Family: Accipitridae; Genus: Accipiter; Species: A. nisus

Family: Accipitridae (Hawks, Eagles, and Kites)

Shape
Generally asymmetrical with a broader trailing vane and a narrower leading vane; rounded tip with a slight taper toward the base.
Size
Approximately 12-14 cm in length. This is consistent with the secondary feathers of an adult Eurasian Sparrowhawk, which typically range from 10-15 cm.

Description

A small, agile raptor with short, broad wings and a long tail adapted for hunting in confined spaces. Males have bluish-grey backs and orange-barred underparts, while females are larger with brown backs and grey-barred undersides.

Colour & Pattern

Classic Accipiter banding: alternating thick bars of dark slate-grey/brown and pale cream/buff. The tip is dark, and the ventral side is lighter with a silvery sheen.

Barb Structure

Tightly interlocked pennaceous structure throughout most of the vane for flight efficiency; slight plumulaceous (downy) texture at the very base near the calamus.

Texture & Surface

Smooth, stiff, and somewhat matte. The surface is designed for silent, efficient air displacement, typical of forest-dwelling raptors that maneuver through dense foliage.

Key Features

Distinctive 'toothed' or wavy look to the pale bands, consistent width of the dark bars, and the specific size profile of an Accipiter secondary.

Habitat

Found in varied woodland, forest edges, and increasingly in urban gardens and parks where small bird prey is abundant.

Geographic Range

Widespread throughout temperate and subtropical parts of the Old World; resident or migratory across Europe, Asia, and North Africa.

Ecological Role

Apex predator of small birds. Plays a vital role in regulating songbird populations and serves as an indicator of a healthy, complex ecosystem.

Similar Species

Northern Goshawk (Accipiter gentilis) feathers are much larger and sturdier; Eurasian Kestrel feathers have different spotting and warmer rufous tones.

Interesting Facts

Sparrowhawks exhibit the highest degree of sexual size dimorphism in any bird species; the female can be up to 25% larger and twice as heavy as the male.

Condition Notes

Good condition. The edges show very minor wear, suggesting it was molted naturally rather than lost through trauma. No visible fault bars.
