Description

The Jamaican woodpecker is about long and weighs . The sexes' plumage is alike except for their head pattern. Adult males have a whitish to buff forehead and are red from their forecrown to hindneck. Adult females have the same white to buffy white forehead but a gray crown with red only on the hindcrown and hindneck. Their upperparts are black with thin white bars that sometimes have a greenish tinge. The bars are widest on the rump and uppertail

. Their flight feathers are black with narrow white bars throughout. Their tail is black with some white bars on the central pair of feathers and white spots on the outermost pair. Their lores are yellowish and their cheeks, chin, and throat are white. Their underparts are mostly olive-gray to olive-buff with yellowish to reddish on the central belly; their lower flanks and undertail coverts are black with white bars. Their bill is long and black, their iris is red, the bare skin around the eye gray to brown, and the legs slaty black. Juveniles are duller than adults, with grayer underparts but a yellower central belly. Their eyes are brown and both sexes have red on their crown but females less than males.Winkler, H. and D. A.

Behavior

The Jamaican woodpecker is a year-round resident throughout its range.

Feeding

for insects.

Breeding

The Jamaican woodpecker's breeding season generally spans from December to August but nesting can occur in any month; pairs often produce two and sometimes three broods in a year. Males do most of the excavation of the nest hole; it is in a dead branch, a dead trunk, or a utility pole and is usually between above the ground. The clutch size is three to five eggs and both sexes incubate the eggs. The incubation period is 13 days and fledging occurs about a month after hatch. Both sexes provision the young as nestlings and for as long as a month after fledging.

Vocal and non-vocal sounds

The Jamaican woodpecker's most common vocalization is "a loud 'kaaa', sometimes repeated 2 or 3 times". Others are "single 'kao' calls in mild alarm", "'wee-cha weecha' in intraspecific encounters", and "'krirr, krirr' and more intimate 'whirr-whirr' during breeding season." Both sexes drum loudly and also tap more softly near the nest hole.

has assessed the Jamaican woodpecker as being of Least Concern. It has a very large range but its population size is not known and is believed to be decreasing. No immediate threats have been identified. It is considered very common throughout the island. However, "although many forest areas are protected, enforcement of laws is often non-existent."
