Great Spotted Woodpecker
Primary flight feather (Remex), likely from the mid-outer wing (P4-P7)

Great Spotted Woodpecker

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Piciformes, Family: Picidae, Genus: Dendrocopos, Species: D. major

Family: Picidae (Woodpeckers)

Shape
Distinctly asymmetrical vane with a narrow leading edge and a broader trailing edge; slightly curved along the rachis with a rounded to slightly blunted tip.
Size
Approximately 7-9 centimeters in length. This is consistent with the primary feathers of a medium-sized woodpecker which typically measure between 6 and 10 cm.
Rarity
Common; one of the most abundant and widely distributed woodpeckers within its extensive range.

Description

This feather belongs to the Great Spotted Woodpecker, a striking bird known for its black and white pied plumage and vibrant red undertail coverts. Adult males also feature a red patch on the nape. Known for their loud 'drumming' on resonant wood, they are agile climbers that use their stiff tail feathers for support while foraging for larvae.

Colour & Pattern

Deep black or brownish-black ground color with prominent, large, rounded white spots (ovate) spaced evenly along both the inner and outer vanes, creating a bold barred effect when the wing is spread.

Barb Structure

Tightly interlocked pennaceous structure throughout most of the vane to provide rigidity for flight; plumulaceous (downy) barbs are present only at the extreme base near the calamus.

Texture & Surface

Smooth and somewhat stiff to the touch; the surface has a slight matte-to-satin sheen. The trailing edge is flexible while the leading edge is reinforced and firm.

Key Features

Bold 'piano key' white spotting on a black feather base; specific rounded shape of the spots; strong asymmetry typical of woodpecker primaries.

Habitat

Woodlands of all types, including deciduous, coniferous, and mixed forests; also common in parks, gardens, and orchards with mature trees.

Geographic Range

Widespread across the Palearctic, ranging from Great Britain and North Africa across Europe and Northern Asia to Japan. Generally resident, though northern populations may irrupt south.

Ecological Role

Primary cavity nester; they create holes that are vital for other 'secondary' cavity-dwelling species like tits, nuthatches, and owls. They also help control wood-boring insect populations.

Similar Species

Syrian Woodpecker (Dendrocopos syriacus) feathers are nearly identical; Middle Spotted Woodpecker (Leiopicus medius) feathers are smaller with more diffuse spotting; Hairy Woodpecker (North America) shows similar patterns but lacks the same geographic overlap.

Interesting Facts

Great Spotted Woodpeckers use 'anvils'—crevices in bark where they wedge nuts or pine cones to peck them open. Their skulls have evolved sophisticated shock-absorption systems to protect their brains during high-velocity drumming.

Condition Notes

Fair to Good. There is some separation of the barbs (zipper-like effect) near the tip and leading edge, suggesting it was molted or subjected to minor mechanical stress.
