White-bellied Woodpecker

The White-bellied Woodpecker is a large, mostly black woodpecker found across South and Southeast Asia, from the hill forests of India and Sri Lanka east through Indochina to Sumatra, Borneo, and Java. It is one of the bulkiest woodpeckers in its range, rivaled only by the even larger Great Slaty Woodpecker in overlapping areas. Its striking white belly patch, glossy plumage, and shaggy crest make it a memorable, if uncommon, sight in mature forest.

Because it depends on large, old trees for both foraging and nest excavation, this species is considered a good indicator of intact forest habitat.

Key features:

• Body and back feathers are deep, glossy black with a slight blue-green sheen in good light
• Lower belly, flanks, and undertail feathers are clean white, a sharp contrast to the black body
• Crest and crown feathers are elongated and pointed; males show red across crown and crest, females show black with red restricted to a smaller area
• Wings are broad and rounded, typical of the genus Dryocopus

Compared to similar species: the Lineated Woodpecker (a different genus but similar build) shows bold white stripes down the sides of the neck and back, which the White-bellied Woodpecker lacks entirely on its back — its white is confined to the belly and vent.

Males have a red forehead, crown, and crest, while females show a black crown and crest with red reduced or largely absent, depending on subspecies. Both sexes share the diagnostic white lower underparts against an otherwise black body. Juveniles resemble females but have duller, sootier plumage and less defined feather edges. Molt follows a typical annual cycle timed around the breeding season, with flight feathers replaced gradually to maintain flight capability.

This species occupies dense evergreen and mixed deciduous forest, favoring areas with large mature trees for nesting and foraging. Its range spans the Western Ghats and Sri Lanka in the Indian subcontinent, continuing through Southeast Asia into the Greater Sundas. It is a non-migratory resident throughout its range, with different subspecies showing some variation in size and the extent of red head coloring in males.

White-bellied Woodpeckers forage on large trunks and heavy branches, prying and excavating bark and dead wood in search of wood-boring beetle larvae, ants, and other insects. Pairs tend to hold large territories in forest interior and are often located by their loud, far-carrying calls before being seen. They excavate nest cavities in large dead or dying trees, a resource that limits their distribution to older forest stands. Drumming is used for territorial communication, and pairs may forage together within a shared territory.
