Red-stained woodpecker

The red-stained woodpecker is a species found across several South American countries, primarily inhabiting the interior of tall rainforests. It is characterized by its yellowish-green upperparts with red feather tips and pale yellow streaks, and its underparts are cinnamon-buff with dark olive-brown bars. This woodpecker is known for its relatively quiet nature, with a primary vocalization consisting of high-pitched nasal notes.

About Red-stained woodpecker

The red-stained woodpecker (Veniliornis affinis) is a species of bird belonging to the woodpecker family, Picidae, and is found across several South American countries, including Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. While taxonomic systems may differ on its genus placement, with some classifying it under Veniliornis and others under Dryobates, its distinct subspecies are universally recognized.

Physical Description and Identification

This woodpecker is relatively small, measuring approximately 15 to 18 centimeters in length and weighing between 32 and 44 grams. Its plumage is predominantly yellowish-green on the upperparts, often adorned with red feather tips and pale yellow streaks, while the underparts are a cinnamon-buff color marked by dark olive-brown bars. A key distinguishing feature between sexes lies in their heads: males typically sport a red crown, whereas females possess a dark olive-brown crown. Both sexes share a golden-yellow nape and hindneck, and a buffish face with olive streaks.

Distribution and Habitat

The red-stained woodpecker is primarily an inhabitant of the interior of tall rainforests. It can also be found in humid lowland forests, including terra firme and várzea types, and occasionally ventures into secondary forests and scrublands, particularly at forest edges. Its altitudinal range varies across its distribution, from near sea level to over 1,300 meters in Peru.

Behavior and Ecology

This species is believed to be a resident throughout its range, not undertaking seasonal migrations. Foraging typically occurs from the mid-level to the canopy, though it may descend lower near forest edges. The red-stained woodpecker often forages alone but will join mixed-species feeding flocks and is known to follow army ant swarms. Its diet comprises arthropods and fruit. While not particularly vocal, its primary sound is a series of high-pitched, nasal notes.

Conservation Status

The International Union for Conservation of Nature (IUCN) has assessed the red-stained woodpecker as 'Least Concern'. This classification is due to its extensive geographic range and a population that is believed to be stable, with no significant immediate threats identified. It is also noted that the species occurs within several protected areas, though it is described as 'very poorly known' and possibly overlooked.
