Eurasian Sparrowhawk

The Eurasian Sparrowhawk is a small, agile bird of prey adapted for hunting other birds through dense woodland, relying on surprise and maneuverability rather than open-sky speed.

Its feathers reflect this lifestyle: short, broad, rounded wings for quick turns among branches, and a long tail for fine steering control.

The species shows marked size differences between the sexes, with females considerably larger than males, and their feather color also differs, males being bluer-grey above and females browner.

Size & Shape

• Wing feathers are short, broad, and rounded, built for rapid acceleration and tight turns rather than sustained soaring.
• Tail feathers are long and barred, providing precise steering through vegetation.
• Female feathers are noticeably larger than male feathers of the same type, reflecting strong reverse sexual size dimorphism.

Color & Pattern

• Male upperpart feathers: blue-grey; underparts show fine, warm rufous-orange barring.
• Female upperpart feathers: browner grey; underparts show brown-grey barring, less warm-toned than the male.
• Tail feathers in both sexes are grey-brown with several dark bands.
• Eye color, reflected in surrounding facial feathering, is orange-yellow in adults.

Similar Species

• Told from the larger, bulkier Common Buzzard by shorter, more rounded wing shape and finer, more regular barring; told from Kestrel by the barred (not spotted) underparts and blunter wing tips.

Overall Plumage

Males: blue-grey above, fine rufous barring below. Females: browner-grey above, brown-grey barring below. Both show a long, banded tail.

Sex & Age Differences

Females are considerably larger than males and browner overall, with less warm barring below. Juveniles of both sexes are brown above with bold, teardrop-shaped streaking below rather than fine barring, gained through a complete molt into adult plumage over their first year or two.

Molt

One complete molt annually, generally in summer, taking several months to complete due to the demands of raising young.

Habitat

Woodland, forest edges, and hedgerows, with increasing use of parks and gardens, especially where small birds gather at feeders.

Range

Widespread across Europe, North Africa, and temperate Asia.

Movements

Mostly resident in milder regions; northern populations may move short distances south in winter.

Behavior

Hunts by surprise, using cover to approach prey and short bursts of speed to catch small birds in flight or on the ground.

Diet

Feeds primarily on small to medium-sized birds, caught in flight or ambush.

Nesting

Builds a stick nest in a tree, often reused or rebuilt in successive years within a woodland territory.

Voice

A fast, chattering 'kek-kek-kek' call, mainly given near the nest.

Field Notes

A finely barred grey-and-rufous flight or tail feather found near woodland or a garden with a plucking site (scattered small-bird feathers) suggests Sparrowhawk activity.
