Chestnut crowned warbler

This little fellow came at sat near us on a bamboo tree in the evening. Since it was raining and the place was warm maybe he enjoyed so much that he did not go home. Was practically undisturbed by our moments and noise. Could not ID it as I did not want to go too close to him and scare him. He was in such an odd position that I could just notice his olive and white streaked body, white underparts and a chestnut cap. Experts Help needed.
