The White-backed Woodpecker (Dendrocopos leucotos) is a Eurasian woodpecker belonging to the genus Dendrocopos.

It is the largest of the spotted woodpeckers in the western Palearctic, 24–26 cm long with wing-span 38-40 cm and has plumage similar to the Great Spotted Woodpecker, but with white bars across the wings rather than spots, and a white lower back. The male has a red crown, the female a black one.[1]

The nominate race D. l. leucotos occurs in central and northern Europe, with the race D. l. lilfordi found in the Balkans and Turkey. Ten further races occur in the region eastwards as far as Korea and Japan. It is a scarce bird, requiring large, mature woods with plenty of dead wood. Numbers have decreased in Nordic countries. In Sweden, its population decline has caused the Swedish government to enact protection for the species in the national Biodiversity Action Plan[2].

In the breeding season it excavates a nest hole about 7 cm wide and 30 cm deep in a decaying tree trunk. It lays three to five white eggs and incubates for 10–11 days. It lives predominantly on wood-boring beetles as well as their larvae, as well as other insects, nuts, seeds and berries. Drumming by males is very loud, calls include a soft kiuk and a longer kweek.
