Here’s a complete natural history profile of the Great Spotted Woodpecker (Dendrocopos major), one of Europe’s most widespread and familiar woodpeckers:

Great Spotted Woodpecker (Dendrocopos major)

Taxonomy & Classification

• Kingdom: Animalia
• Phylum: Chordata
• Class: Aves
• Order: Piciformes
• Family: Picidae (woodpeckers)
• Genus: Dendrocopos
• Species: D. major

General Description

• Size: 23–26 cm in length; wingspan 38–44 cm.
• Weight: 70–100 g.
• Plumage:
  • Black and white upperparts with bold contrasting markings.
  • White cheeks and shoulder patches.
  • Red undertail coverts.
  • Males: Red patch on the nape.
  • Females: Lack the red nape patch.
  • Juveniles: Red crown, which fades as they mature.
• Bill: Strong, chisel-like, adapted for drilling wood.
• Feet: Zygodactyl (two toes forward, two backward), for gripping bark.

Behavior & Lifestyle

• Foraging:
  • Specializes in excavating wood for insects and larvae.
  • Known to wedge nuts or pine cones into crevices (called “anvils”) to hammer them open.
  • Opportunistic — in winter also eats seeds, berries, and visits bird feeders.
• Drumming:
  • Rapid bill-hammering on dead wood serves as a territorial signal and courtship display.
  • Each individual’s drumming rhythm can be distinctive.
• Flight: Undulating, with alternating flaps and glides.

Diet

• Primary food: Wood-boring beetle larvae, ants, and other insects.
• Secondary food: Nuts, seeds (especially pine), berries, and occasionally bird eggs or nestlings.

Reproduction & Life Cycle

• Breeding season: April–June.
• Nest: Excavated in dead or decaying trees; both sexes help carve out the cavity.
• Clutch size: 4–6 glossy white eggs.
• Incubation: ~10–12 days, shared by both parents.
• Fledging: Chicks leave the nest after about 20–23 days, fed by both parents.
• Family bonds: Parents defend nest vigorously against intruders, including other woodpeckers.

Habitat

• Found in a wide range of wooded environments:
  • Deciduous and mixed forests
  • Parks and gardens
  • Farmland with scattered trees
• Requires mature trees for nesting cavities and foraging.

Geographic Range

• Widespread across Europe and Asia, from Iberia to Japan.
• Absent from Ireland and northernmost Scandinavia, but expanding in some areas.
• Non-migratory, though some northern populations may move south in harsh winters.

Ecological Role

• Predator: Controls populations of wood-boring insects.
• Ecosystem engineer: Creates tree cavities that are later used by other birds (e.g., nuthatches, owls, tits) and mammals (e.g., bats, dormice).
• Seed disperser: Helps open cones and spread seeds.

Special Adaptations

• Shock absorption: Skull and bill adapted to withstand repeated hammering without brain damage.
• Long, sticky tongue: Can extend far beyond the bill to extract insects from deep crevices.
• Cavity creation: Ability to excavate nesting sites in otherwise impenetrable wood.

Conservation Status

• IUCN Red List: Least Concern.
• Population trend: Stable or increasing in many areas.
• Threats:
  • Local declines from loss of mature trees due to logging or urbanization.
  • Competition for nest sites with invasive species like the Rose-ringed Parakeet in some cities.
• Conservation measures: Retention of deadwood and mature trees in managed forests supports population health.

Interesting Facts

• Their drumming can reach 10–15 strikes per second.
• Known to sometimes raid nests of smaller birds for eggs or chicks.
• Juvenile Great Spotted Woodpeckers often beg noisily and can be heard before they are seen.
• Increasingly common at garden bird feeders, where they often take peanuts and suet.
