Striped Woodpecker

This small-sized member of the Picidae family is distinguished by a compact body length of approximately 5.9 to 6.3 inches (15 to 16 centimeters). The plumage pattern of Veniliornis lignarius displays an intricate barred pattern of black and white bands, resembling a zebra-like coloration. The underparts are predominantly dingy white to pale grey, heavily marked with dark, vertical streaks. Sexual dimorphism is clearly visible: males feature a small but bright red patch on the nape or back of the crown, which is entirely absent in females, who possess a uniform dark brown or blackish crown. The bill is strong, chisel-like, colored slate grey, and optimized for wood-boring, while the iris ranges from reddish-brown to deep red.

Geographical distribution: The species is endemic to the southern portion of South America. Its range predominantly spans Chile, from the Coquimbo region southward to the Brunswick Peninsula in Magallanes, and western Argentina, where it occupies the Andean-Patagonian forest corridor from Neuquén down to Tierra del Fuego. Disjunct populations have also been documented in the high-altitude montane forests of northwestern Argentina, including the provinces of Salta and Jujuy, where they inhabit transitional scrub and woodland zones.

Habitat: It is closely associated with temperate deciduous and evergreen forests, particularly those dominated by Nothofagus species such as lenga, coihue, and ñire. Additionally, this bird occupies semi-arid scrublands, forest edges, riparian corridors, agricultural orchards, and mature suburban gardens. Its altitudinal range extends from sea level up to 6,500 feet (approximately 2,000 meters) above sea level, showing high adaptability to both humid coastal zones and drier Andean mountain slopes.

Feeding: The diet is primarily insectivorous, focusing heavily on wood-boring larvae, beetles, ants, and other invertebrates found beneath tree bark. It utilizes its robust bill to flake off bark and excavate shallow cavities in decaying wood, subsequently employing its long, sticky, and barbed tongue to extract hidden prey from narrow galleries. During periods of low insect availability, it may supplement its nutritional intake by consuming tree sap or foraging on small native berries.

Behavior: Typically observed as a solitary individual or in monogamous pairs, this bird exhibits a characteristic undulating flight pattern. It spends most of its active hours climbing vertically up trunks and large branches, utilizing its stiff tail feathers as a prop and its zygodactyl feet to maintain a firm grip on vertical surfaces. Territorial defense and communication are achieved through sharp, metallic vocalizations and rhythmic wood-drumming on resonant dry branches, which is performed by both sexes.

Nesting: The breeding season occurs from October to January. This cavity-nesting species excavates its own nesting chamber in dead tree trunks or decaying branches, typically situated at heights of 6 to 26 feet above the ground. The female lays a clutch of 3 to 5 pristine white eggs. Both parents actively participate in incubation for a period of 12 to 14 days, and both cooperate in brooding and feeding the altricial chicks with insect larvae until they fledge.

Conservation status: It is currently classified as Least Concern (LC) on the IUCN Red List. Although the global population appears stable and is not facing immediate threats, the loss of mature old-growth forests and the removal of dead standing trees due to forestry practices present localized challenges by reducing suitable nesting cavities.
