European green woodpecker
species of bird

The European green woodpecker (Picus viridis), also known as the yaffle and sometimes called a nickle, is a large green woodpecker with a bright red crown and a black moustache. Males have a red centre to the moustache stripe which is absent in females. It is resident across much of Europe and the western Palearctic but in Spain and Portugal it is replaced by the similar Iberian green woodpecker (Picus sharpei).
The European green woodpecker spends much of its time feeding on ants on the ground and does not often 'drum' on trees like other woodpecker species. Though its vivid green and red plumage is particularly striking, it is a shy bird, and is more often heard than seen, drawing attention with its loud calls. A nest hole is excavated in a tree; four to six eggs are laid which hatch after 19–20 days.
Taxonomy
The European green woodpecker was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under its current binomial name Picus viridis. The type locality is Sweden. The scientific name is derived from the Latin picus, meaning "woodpecker", and viridis meaning "green". It is member of the order Piciformes and the woodpecker family Picidae.
This brief starts where responsible research should: with the source description of “European green woodpecker” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q166171. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1758.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
