Main breeding range lies from Europe east to Sakhalin, Hokkaido, throughout much of China, the Himalayas and southeast China south to Vietnam.

In Europe breeds in southern Scandinavia and central and eastern Europe south to northern Greece and eastwards to the Urals. Also has a patchy distribution further west breeding in west and central France, Luxembourg and central and southern Germany, northern Switzerland, northern Italy and more widely in Austria.

Recently found to be breeding in northeastern and western Turkey. In the east of range there are isolated populations in north-east India, on Taiwan and Hainan, and the mountains of Malaysia and Sumatra.

Mainly resident but short-distance dispersal common and altitudinal movements recorded. Very rarely seen outside breeding range but has been recorded in the Spanish Pyrenees, the Netherlands and Turkey, and in March 1992 reported in Circeo National Park, Italy, well south of known Italian range.

[edit] Taxonomy

Complex; recently split into three species by BirdLife International[1], though not yet by other authorities[2][3].

      Described above
    • P. c. jessoensis - eastern Siberia to north-eastern China, Korea and northern Japan
      Greyer mantle
  • Picus guerini group (Black-naped Woodpecker; upland southern and eastern Asia)
    Black crown and nape with red forecrown in males, black crown and nape in females; more strongly green-grey underparts; wings green in Chinese subspecies, tinged yellowish-green in Himalayan subspecies, and increasing orangey-brown toned in Indochinese subspecies.

    • P. c. sanguiniceps - western Himalayas
    • P. c. hessei - eastern Himalayas to Burma and Indochina
    • P. c. robinsoni - western Malaysia
  • Picus dedemi (Sumatran Woodpecker; endemic, Sumatra)
    Small; mantle, underparts, and wings dark red-brown; crown and nape black.

[edit] Habitat

Grey-headed Woodpecker occurs in diverse woodlands including coniferous taiga forest, temperate deciduous woodland and subtropical forest, bamboo groves. Where both occur usually found in more upland areas than Green Woodpecker. In Scandinavia found in coniferous forest mixed with aspen but in central Europe found in deciduous and riparian forest, small woods in farmland, parks and large gardens; in Balkans also in mixed mountain forests. Black-naped Woodpecker and Sumatran Woodpecker occur in middle to higher elevation (900–2600 m altitude) montane forests.

[edit] Behaviour

[edit] Diet

Like other species of Picus, often feeds on the ground, usually solitary. Though the diet consists mostly of ants, also takes other food sources and will come to bird feeders in winter, taking peanuts and suet.

[edit] Vocalisation

Drums more frequently than Green Woodpecker.
Late afternoon calls in the forest as bird was moving from one perch to another. Occasional calls by Black-lored Tit can be heard in the BG.
