Nidification. In March 1878 Col. T. C. Bingham took a nest of this Warbler in Tenasserim. It was built of fibres inside a bamboo which had been cut down but left standing against the clump; the entrance was merely the irregular hole made by the chance cut of the dao by some one in cutting the bamboo down. It contained three eggs, pinkish white with pinkish-claret spots, and measuring .57 X .42, .59 x .42 and .59 x .44 mm.
Habits. Similar to those of the preceding bird. During the breeding-season it keeps much to forest and bamboo-jungle but in Winter may be seen in any well-wooded country.
