Dendrocopos leucotos

SUBFAMILY

Picinae

TAXONOMY

Picus leucotos Bechstein, 1802.

OTHER COMMON NAMES

English: Owston's woodpecker; French: Pic à dos blanc; German: Weissrückenspecht; Spanish: Carpintero de Lomo Blanco.

PHYSICAL CHARACTERISTICS

9.8–11.0 in (25–28 cm), 3.2–5.6 oz (92–158 g); A pied woodpecker with white cheeks, white forehead and lower back, white breast shading to pale pink and deeper pink vent area; male with prominent red cap; female with black cap. Birds in southeast Europe have vermiculated white back.

DISTRIBUTION

Found in a broad band across forested areas of northern Eurasia from Fennoscandia to Kamchatka and Japan; many isolated populations in montane and island areas

HABITAT

Wet mixed forest, often near rivers or lakes

BEHAVIOR

Has a large home range, moving great distances to areas with many dead and dying trees in order to find preferred foods. Drumming has been likened to a bouncing ping-pong ball— a strong beginning accelerating to a weaker end "bouncing to a halt."

FEEDING ECOLOGY AND DIET

Feeds primarily on insects, especially wood–boring beetles; spends considerable time excavating beetle larvae from near the base of willows and alders.

REPRODUCTIVE BIOLOGY

Courtship often begins in February; nests often high in rotted stub or utility pole; clutch of 3–5 eggs incubated by both parents for 14–16 days; both adults tend nestlings which fledge at 27–28 days.

CONSERVATION STATUS

Not threatened globally, but considered regionally threatened by forest clearing and disturbance.

SIGNIFICANCE TO HUMANS

None known.

(Bechstein, 1802)

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

It is the largest of the spotted woodpeckers at 24–26 cm long 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.

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[1].

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.
