Chrysocolaptes festivus (Boddaert, 1783)

Scientific Naming and Size

The white-naped woodpecker (scientific name Chrysocolaptes festivus (Boddaert, 1783)) is a large woodpecker species, measuring 29 cm (11 in) in length. It has the typical shape characteristic of woodpeckers.

Neck and Back Markings

A white hind neck extends down along its back, and black shoulder patches continue onto the back to form a V-shape that borders the white area. The remaining parts of the upperparts and wings are golden yellow.

Rump, Tail and Underpart Coloration

Its rump and tail are black, while the underparts are white with dark chevron markings.

Head Markings

The head is whitish, marked with a dark moustache stripe and a black eye patch that extends down the sides of the neck.

Adult Crown Color Dimorphism

Adult males of this species have a red crown, while females have a yellow crown.

Juvenile Plumage

Young birds share the same color pattern as females, but their plumage is duller overall.

Morphological Adaptations

Like other woodpeckers, the white-naped woodpecker has a straight, pointed bill, a stiff tail that provides support against tree trunks, and zygodactyl or "yoked" feet, with two toes pointing forward and two pointing backward. It also has a long tongue that can dart forward to capture insects.
