The European green woodpecker (Picus viridis) 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.
There are three subspecies, with subtle and mostly clinal differences between them.
P. v. viridis Linnaeus, 1758, which breeds in Europe south to France (except south Roussillon where it is replaced by the Iberian green woodpecker), the Alps, Croatia, Slovenia and Romania P. v. karelini von Brandt, JF, 1841, which breeds in Italy, south-east Europe south from North Macedonia, Montenegro, Serbia, Bulgaria, Asia Minor, northern Iran and south-west Turkmenistan. It has duller green upperparts, cheeks and underparts than viridis P. v. innominatus (Zarudny & Loudon, 1905), which breeds in south-west and southern Iran, is like karelini but with nearly white cheeks, throat and chest and more defined barring on the tail.
The Iberian green woodpecker (Picus sharpei) and Levaillant's woodpecker (Picus vaillantii) were formerly considered as subspecies of the European green woodpecker. They are now treated as separate species based on the results of two molecular phylogenetic studies published in 2011.
Description
The European green woodpecker measures in length with a wingspan. Both sexes are green above and pale yellowish green below, with yellow rump and red crown and nape; the moustachial stripe has a red centre in the male but is solid black in the female. The lores and around the white eye are black in both male and female, except in the Iberian race P. v. subsp. sharpei, in which it is dark grey and males have only a lower black border to the moustache. Juveniles are spotty and streaked all over; the moustache is dark initially, though juvenile males can show some red feathers by early June or usually by July or August.
Moult takes place between June and November with the first flight feathers being lost around the time the young fledge. Juveniles moult quickly after fledging and gain their adult plumage between August and November.
Although the European green woodpecker is shy and wary, it is usually its loud calls, known as yaffling, which first draw attention. It 'drums' rarely (a soft, fast roll), but often gives a noisy kyü-kyü-kyück while flying. The song is a loud series of 10–18 'klü' sounds which gets slightly faster towards the end and falls slightly in pitch. The female makes a thinner pü-pü-pü-pü-pü-pü-pü. The flight is undulating, with 3–4 wingbeats followed by a short glide when the wings are held by the body.
It can be distinguished from the similar, but smaller, grey-headed woodpecker by its yellowish, not grey, underparts, and the black lores and facial 'mask'. In Europe, its green upperparts and yellow rump can lead to confusion with the grey-headed woodpecker or possibly the female golden oriole, though the latter is smaller and more slender with narrower wings and longer tail. The closely related, very similar Levaillant's woodpecker occurs only in north-west Africa.
Distribution and habitat
More than 75% of the range of the European green woodpecker is in Europe, where it is absent from some northern and eastern parts and from Ireland, Greenland and the Macaronesian Islands, but otherwise distributed widely. Over half of the European population is thought to be in France and Germany, with substantial numbers also in United Kingdom, Sweden, Russia, Croatia, Romania and Bulgaria. It also occurs in western Asia.
