Choco Woodpecker

The Choco Woodpecker (Veniliornis chocoensis) is a small to medium-sized woodpecker in the family Picidae, endemic to the humid lowland and foothill forests of the Chocó biogeographic region on the Pacific slopes of Colombia and northwestern Ecuador. It belongs to the genus Veniliornis, a group of small Neotropical woodpeckers characterised by their compact build, relatively short bills, and often barred or spotted plumage combining greens, browns, and reds. The male Choco Woodpecker has a red cap, while the female's crown is dark. Both sexes show strongly barred underparts. It inhabits the interior and edge of humid tropical forest from sea level to around 1,200 metres, where it excavates nesting and roosting cavities in dead or dying trees and forages for wood-boring beetles, ants, and other invertebrates by pecking, chiselling, and probing bark and dead wood. The IUCN classifies the Choco Woodpecker as Near Threatened. Its dependence on intact and mature forest with sufficient dead wood substrate makes it vulnerable to the rapid, ongoing deforestation occurring in the Colombian and Ecuadorian Pacific lowlands and foothills, where large areas of forest have been converted to agriculture and human settlements over recent decades.
