Rufous-headed woodpecker

The Rufous-headed woodpecker (Celeus spectabilis) is a striking bird species found in the humid tropical rainforests of South America, specifically in eastern Ecuador, northeastern Peru, southeastern Peru, Brazil's Acre state, and northern Bolivia. This species typically inhabits areas along rivers and on their islands, often associating with bamboo thickets or landscapes featuring Cecropia trees.

Description and Identification

Adult Rufous-headed woodpeckers measure approximately 26 to 28 cm in length. The most distinguishing feature is their rufous-chestnut head. Adult males possess a vibrant deep red malar patch and a prominent, bushy crest, while females lack the red malar and have at most a trace of red on their crest. Both sexes share a cream-buff patch on the neck that extends down the side of the breast, contrasting with a black lower throat and breast. Their upper back is creamy buff to pale cinnamon-yellow with very wide black bars, while the lower back and rump are yellow-buff to cinnamon-buff. The wings feature black coverts with cream-buff edges and narrow bars, and their primaries are brownish-black with rufous bases. The iris of their eyes is a deep red-brown, and their legs are olive green to grayish. Juveniles resemble adults but have darker bills and more blackish coloration on the front of their heads.

Behavior and Ecology

The Rufous-headed woodpecker is a year-round resident within its range. Its diet is believed to consist mainly of bamboo ants, though other insects are likely consumed. Foraging occurs singly or in pairs at various levels of the forest, including on fallen logs. They employ probing and forceful pecking techniques to uncover prey within tree trunks, branches, and bamboo.

Vocalizations are notable and include a loud, squealing song, a mewing chuckle, and harsh squawks when agitated. Their drumming on hollow bamboo produces loud, evenly pitched rolls. Breeding information is limited; the known breeding season in Peru spans at least from June to August. Nests have been observed in dead snags and live trees, with one instance of a male provisioning a single chick.

Distribution and Habitat

The nominate subspecies, C. s. spectabilis, is found in eastern Ecuador and northeastern Peru. The subspecies C. s. exsul inhabits southeastern Peru, Brazil's Acre state, and the Beni and Cochabamba departments of northern Bolivia. They are usually found at elevations up to about 300 meters.

Conservation Status

The International Union for Conservation of Nature (IUCN) has assessed the Rufous-headed woodpecker as Least Concern. Despite having a fairly large range, its population size and trend are not precisely known. No immediate threats have been identified, although it is considered generally rare in Brazil and its strict habitat requirements and low density suggest it may warrant further conservation consideration.
