Habits. The Chestnut-headed Wren has been found as high as 11,000 feet in Sikkim and, on the other hand, Stevens has found them in the low foot-hills of the Assam Himalayas. In their haunts and actions they very closely resemble Tesia cyaniventer. Osmaston says:—"This pretty little bird, like Tesia, has the habits of a Wren and frequents brushwood under high forest, rarely ascending more than a few feet above the ground. It is common in the neighbourhood of Darjeeling at all elevations up to 8,000 feet, according to season.
"It has a shrill call of four notes resembling that of Culicicapa ceylonensis which it utters as it moves restlessly about in thick cover."
It is entirely insectivorous in its diet and just as averse to taking flight as is the Slaty-bellied Wren.
