Nidification. Gammie took a nest and three eggs of this bird in Sikkim at a little under 2,000 feet elevation. The nest of bamboo-leaves and pine-roots was placed inside a bamboo resting on one of the nodes, above which someone had cut a hole in the bamboo. The eggs were pinky-white, densely freckled at the large end and less so elsewhere with reddish brown and purple. They were taken on the 15th June, and one egg measured 15.5 x 10.9 mm.
Habits- This little Flycatcher-Warbler is found between the foot-hills and about 4,000 feet elevation, wandering into the plains of Bengal and Assam in Winter. It keeps very much to thin forest, secondary growth and bamboo-jungle, and is very partial to the banks of tiny streams. It is a lively, active little bird with a sweet, though very shrill little song. It appears to catch its insect-food almost entirely on the wing.
