Similar Species

Very similar to the Syrian Woodpecker of southeastern Europe and southwestern Asia, differing most obviously in the moustachial stripe extending back across the lower cheek to the rear of the crown. Juveniles with a red forecrown can be confused with Middle Spotted Woodpecker, but have a stouter bill and stronger moustachial stripe.

Variations

Typically the northern subspecies are larger, with shorter, stouter bills, and whiter underparts. The north African subspecies, D. m. mauritanus and D. m. numidus are cream below with a bold chest band, black at the sides and red in the centre, and more extensive red on the undertail coverts and belly. The Canary Islands subspecies, D. m. canariensis from Tenerife is creamy-buff below, and D. m. thanneri from Gran Canaria is more greyish.

Distribution

Resident throughout range but may be irruptive in the north. One of the most widespread and abundant of the spotted woodpeckers, it breeds from eastern Ireland (where a recent colonist), throughout Britain, most of Scandinavia except the far north and the highest mountains, throughout Europe from Iberia (although scarce in southern Spain) to northern Greece, and east to Kamchatka, Sakhalin, Japan, Korea and China.

Also breeds on the Canary Islands, Corsica, Sardinia and Sicily and isolated populations in the Caucasus and in parts of southern Greece and northern Turkey, in Morocco and northern parts of Algeria and Tunisia. Further east the southern limits of range are reached in north-east India, Vietnam and Hainan.

Vagrants have been recorded in Iceland and the Faroes.

Taxonomy

About 14 subspecies are recognised, differing slightly in overall size, bill size and colour of underparts. However there is much intergradation in mainland races and also variation within races.

  • D. m. cabanisi:
  • D. m. stresemanni:

Habitat

Deciduous, coniferous or mixed woodland and forest, parks and orchards, sometimes in large gardens.

Behaviour

Diet

Although the diet usually consists of insects and their larvae, woodpeckers are not averse to preying on young birds in the nest and will smash their way into nest boxes to do this. In areas where woodpeckers are known to be active, a protective sheet of metal may be fitted to the entrance of the box.

Conifer seeds form an important part of the winter diet, particularly in Northern Europe. Cones may be taken to an 'anvil' to assist in the removal of seeds. The 'anvils' may be a hard surface, on which the cone is balanced, or a crevice, either natural, or one which they have prepared themselves, by cutting back the bark to create a crack.

Vocalisation

The call is a loud 'tchk'. The drumming sound is made by the male, using a dead dry tree that generates a good volume, to attract a female. The sound can travel over hundreds of metres in favourable conditions. Feeding uses a much less rapid pecking action and the quieter sound generated can only be heard at close quarters.
