The White-browed Woodpecker (*Piculus aurulentus*) is a striking bird of South America’s Atlantic Forest, easily recognized by its vivid golden-yellow crown and the bold white stripe above its eye that gives it its name. Its body is a rich olive-green above with a barred yellow and black belly, while males boast a red throat patch that females lack, adding a splash of color to their otherwise cryptic plumage. A unique specialist, this woodpecker is notable for its strong association with bamboo thickets, where it forages for insects and larvae using a distinctive, deliberate pecking rhythm rather than rapid drumming. Its relatively long, chisel-like bill and stiff tail feathers allow it to cling vertically to bamboo stalks, making it a master of this niche habitat. Despite its beauty, the species is threatened by deforestation, making each sighting a precious glimpse of a forest gem in decline.

Faits amusants

Despite its name, the white-browed woodpecker’s most flamboyant feature isn’t its brow but its vivid golden-olive back and fiery red throat and crown, making it look like a tiny, feathered jewel. It engages in a quirky “drumming duet” with its mate, where one bird taps a rapid, hollow rhythm on a tree and the other answers with a slightly different beat, a behavior used to reinforce pair bonds rather than just claim territory. As a specialized forager, it often hangs upside-down like a tiny acrobat to pry bark loose with its chisel-like bill, and it has a remarkably long, barbed tongue that it can extend far beyond its beak to spear wood-boring beetle larvae from deep within their tunnels.

Habitats et répartition

This woodpecker inhabits the humid Atlantic Forest of South America, primarily found in lowland and montane evergreen forests, including secondary growth and forest edges. It shows a preference for mature forests with large trees, particularly those with abundant dead wood or epiphytic bromeliads where it forages for insects and larvae. Its geographical range is restricted to a relatively narrow strip along the southeastern coast of Brazil, from the state of Espírito Santo south to Rio Grande do Sul, with additional populations extending into northeastern Argentina (Misiones) and possibly eastern Paraguay. The species is generally non-migratory and remains within these forested regions year-round.

Comportements & Reproduction

This species is generally observed alone or in pairs, suggesting a monogamous social structure during the breeding season. Courtship involves vocal duets and mutual preening, with pairs defending a small territory around their nesting cavity. They are secondary cavity nesters, typically excavating a new hole in a dead tree or palm stump each season, which serves as a unique reproductive strategy to reduce parasite loads. The female lays 2–4 white eggs, and both parents share incubation duties for about 12–14 days, followed by biparental care of the altricial young for several weeks after fledging. No cooperative breeding or extra-pair copulations have been documented for this species.

Alimentation

The White-browed Woodpecker is primarily insectivorous, with a diet heavily focused on wood-boring beetle larvae, ants, and termites, which it extracts by chiseling into dead or decaying wood with its powerful beak. It also consumes other arthropods like spiders and caterpillars, and supplements its diet with small amounts of fruit, berries, and tree sap, particularly during non-breeding seasons when insect prey may be less abundant. An interesting fact is that this species often forages in mixed-species flocks, following army ant swarms to capture insects flushed by the ants, and it occasionally uses its long, barbed tongue to lick sap from small holes it drills in tree bark, a behavior more commonly associated with sapsuckers.

Couleurs

The White-browed Woodpecker has an olive-green back and wings, a yellow throat and chest, and a bright red crown and nape in males, while females have a black crown. Its most distinctive feature is a bold white brow stripe above the eye, contrasting with a blackish face and ear coverts. The underparts are barred with dark olive and yellow, and the tail is black. This greenish and barred pattern provides effective camouflage against tree bark and foliage in its forest habitat.
