Small Yungas woodpecker measuring approximately 18 cm in length, with a generally dark olive-brown and fairly uniform plumage. The face is paler, with whitish cheeks contrasting with the rest of the plumage. Wings and tail are somewhat darker. The male has a red crown, usually appearing dull because of the dark bases of the feathers, while the female lacks red and shows a uniformly brown head. Both sexes have dark brown to reddish-brown irises, a relatively long and straight blackish bill, and grayish legs. Juveniles are duller and browner than adults. It can be easily distinguished from the Olive Woodpecker (Dryobates spilogaster), a species more widespread in the Argentine Yungas, by its much more uniform plumage, as the Olive Woodpecker shows pale spots on the back and distinct barring on the underparts.
Geographic Distribution: It is distributed from Mexico to northwestern Argentina, mainly following the mountainous regions of Central America and the Andes. In Argentina, it reaches the southernmost limit of its range and is restricted to the northern sector of the Yungas in Jujuy and Salta Provinces, where it is considered a highly localized and seldom-observed species. It occurs mainly between 1,000 and 2,800 m above sea level, although many records come from montane forests dominated by alders (Alnus sp.).
Habitat: It is closely associated with humid montane forests of the Yungas, particularly alder forests and areas containing abundant mature trees and decaying wood. It primarily uses the middle forest stratum, although it may move both lower and higher while searching for food. It also frequents forest edges, humid ravines, and areas with lianas and dense vegetation.
Diet: It feeds mainly on small wood-boring beetles and their larvae, supplementing its diet with other arthropods and occasionally fruits. It searches for food by exploring trunks, branches, and lianas, where it pecks and probes bark crevices. It generally forages in pairs and frequently joins mixed-species flocks.
Behavior: It is usually observed alone or in pairs. This active and wide-ranging woodpecker explores different sectors of the forest in search of food. It moves along trunks, branches, and lianas with agile motions, spending long periods inspecting bark surfaces. In the field, it often goes unnoticed because of its scarcity, its low-contrast plumage, and its tendency to use trees covered with mosses and epiphytes, where it blends in remarkably well. Furthermore, once it moves to another tree, it is often difficult to relocate (personal observation). Its vocalizations consist of short, high-pitched calls, as well as rapid series of harsh and dry notes. It also performs very rapid and prolonged drumming.
Nesting: Both members of the pair excavate the nesting cavity in dead trunks or branches, and occasionally even in fence posts. The known clutch consists of four white eggs.
Conservation Status: Classified as Least Concern (LC) at the international level. In Argentina, it has no national threat category, although its distribution is much more restricted and localized than that of other Yungas woodpecker species. Its presence appears to be closely linked to the conservation of alder forests and humid montane forests in the northern Argentine Yungas. It is protected in areas such as Calilegua National Park, Baritú National Park, El Nogalar de los Toldos National Reserve, and Potrero de Yala Provincial Park, which preserve some of the most important habitats for the species in the country. There is also an isolated record from Aconquija National Park in Tucumán Province, suggesting a possible occasional occurrence farther south than its currently known distribution in Argentina, although additional records would be required to confirm its regular presence in that province.
