Habits. Wait says that this little Flower-pecker is mainly confined to the forest of the wet low country zone but that it has been found up to 3,000 feet in the Central Province. It is a rare little bird and but little has been recorded about it. It is said to live in dense forest or in its immediate vicinity, associating in small flocks and hunting among creepers on tree-trunks for berries.
