The Antillean piculet (Nesoctites micromegas) is a species of bird in subfamily Picinae of the woodpecker family Picidae.

[3] A fossil feather in amber attributed to the genus has been found in the Dominican Republic, showing that the ancestors of the species have been isolated on Hispaniola for at least 25 million years.

Adult males of the nominate subspecies have a lemon yellow crown with an orange-red to red patch in the center.

Juveniles are overall duller than adults, do not have a red crown spot, and have obscure barring rather than streaks on their underparts.

Subspecies N. m. abbotti is paler than the nominate and has less yellow on the crown, grayer upperparts, a plainer white throat, and less heavy streaks on the underparts.

It mostly hunts by gleaning small branches, twigs, and vines rather than tree trunks, and also probes flowers and clusters of leaves and pine needles.

It excavates a nest hole or occupies one abandoned by another woodpecker, typically within 5 m (16 ft) of the ground in a stump, tree, palm, or fence post.
