The Antillean Piculet is a small woodpecker endemic to open forested habitats, especially in dry areas, on Hispaniola. It resembles the smaller Picumnus piculets of the continental Americas, but is not clearly related to that group. It is dull green above and white below with black streaking. Both sexes have a yellow crown, but the male also has an orange spot on the rear crown. This species occurs singly or in pairs, foraging low in vegetation more by gleaning than pecking. The Antillean Piculet excavates a cavity nest and is quite territorial.
