Eurasian Wryneck

The Eurasian wryneck sometimes forms small groups during migration and in its winter quarters but in the summer is usually found in pairs. It characteristically holds its head high with its beak pointing slightly upwards. A mutual display that occurs at any time of year involves two birds perched facing each other with their heads far back and beaks wide open, bobbing their heads up and down. Sometimes the head is allowed to slump sideways and hang limply. On other occasions, when excited, the head is shaken and twisted about violently. When disturbed on the nest or held in the hand, the neck contorts and twists in all directions. The bird sometimes feigns death and hangs limply with eyes closed. On returning to the breeding area after migration, the birds set up territories. On farmland in Switzerland it has been found that old pear orchards with large numbers of ant nests are preferentially selected over other habitats. Areas used for vegetable cultivation provided useful habitat when they include areas of bare ground on which the birds can forage. Territories are not chosen at random as arriving birds favoured certain areas over others with the same territories being colonised first year after year. The presence of other Eurasian wrynecks in the vicinity is also a positive influence. Orchards in general, and older ones in particular, provide favoured territories, probably because the dense foliage is more likely to support high numbers of aphids and the ground beneath has scant vegetation cover, both of which factors increase the availability of ants, the birds' main prey. Despite some territories being consistently chosen over others, reproductive success in these territories was no higher than in others. Limiting factors for such crevice-nesting species as Eurasian wrynecks are both the availability of nesting sites and the number of ants and their ease of discovery. Modern farming practices such as the removal of hedges, forest patches and isolated trees and the increasing use of fertilisers and pesticides are disadvantageous to such birds. The diet of the Eurasian wryneck consists chiefly of ants but beetles and their larvae, moths, spiders and woodlice are also eaten. Although much time is spent in the upper branches of trees, the bird sometimes perches in low bushes and mostly forages on the ground, moving around with short hops with its tail held in a raised position. It can cling to tree trunks, often moving obliquely, and sometimes pressing its tail against the surface as a prop. It does not make holes in bark with its beak but picks up prey with a rapid extension and retraction of its tongue and it sometimes catches insects while on the wing. Its flight is rather slow and undulating.

The Eurasian wryneck has a palearctic distribution. The breeding range of the nominate subspecies includes all of Europe from Britain to the Urals. In the north it reaches the Arctic Circle and the range includes Spain in the southwest. In the south and east it intergrades with J. t. tschusii (smaller and more reddish brown) which is found in Corsica, Italy, Dalmatia and parts of the Balkans. J. t. mauretanica (also smaller than the nominate form, light, with whitish throat and breast) is resident in Algeria and Morocco and possibly also the Balearic Islands, Sardinia and parts of Sicily. J. t. sarudnyi (considerably paler than the nominate with fainter markings) occurs in the Urals and then in a wide strip of Asia through southern Siberia, Central Asia, including the north-western Himalayas to the Pacific coast. J. t. chinensis breeds in eastern Siberia and northeastern and central China while J. t. himalayana breeds in Pakistan and the northwestern Himalayas. Eurasian wrynecks also inhabit the island of Sakhalin, Japan and the coastal areas of southern China. The Eurasian wryneck is the only European woodpecker to undertake long distance migrations. The wintering area of European species is located south of the Sahara, in a wide strip across Africa extending from Senegal, Gambia and Sierra Leone in the west to Ethiopia in the east. Its southern limit extends to the Democratic Republic of Congo and Cameroon. The populations from West Asia use the same wintering areas. The Central and East Asian breeding birds winter in the Indian subcontinent or southern East Asia including southern Japan. During the summer the bird is found in open countryside, parkland, gardens, orchards, heaths and hedgerows, especially where there are some old trees. It may also inhabit deciduous woodland and in Scandinavia it also occurs in coniferous forests.
