The Banded woodpecker is a medium-sized woodpecker with a distinctive yellow-nape, and presently the only yellow-naped woodpecker in Singapore. Both sexes have a red crown, and the male (as seen here) also has red on the neck sides.
Primary forest (Bukit Timah Nature Reserve, one of the largest patches of primary rainforest left in Singapore)
This bird is found in Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand. Also recently often sighted in Singapore is the Crimson-winged Woodpecker (Picus puniceus); this species is predominantly olive-green and can be distinguished by its blue eye-ring.
