Habitat: It is found in Montane forest, scrub and thickets. It is found from 2000m up to 5000m from sea level.

Food Habits: It eats small insects and spiders; also, mainly in autumn and winter, small quantities of seeds and berries. The nestlings are fed insects and spiders. It forages among herbs and shrubs, where very active and agile; it forages on ground, investigating root tangles and lichen-covered rocks. It catches insects by aerial flycatching. In winter months may join mixed-species foraging flocks

Breeding habits:  They breed in May to Jun. They are single-brooded. The nest is built by both sexes, work divided equally, taking 6–8 days for framework and almost as long for lining. The nest is an oval ball with circular entrance on one side towards top, outer layer of coarse material such as large pieces of moss, thin stalks, spider cocoons, and lichen. The inner layer is of same material as well as plant hair, wool, dead leaves, feathers and the like, and lining mainly of feathers. They use downy feathers from Himalayan Snowcock  and Chukar partridge to stick up in nest and form “elastic funnel” at entrance. When adult enters, the entrance closes behind it. The nest are very well concealed in scrub ,usually in upper part of bush, supported by small branches at sides and base, with walls woven around larger branches. They lay a clutch of 4–8 eggs .The incubation is done by both sexes. The incubation period is14–17 .Both the sexes brood chicks for first c. 7–8 days, and roost in nest with them. The young leave nest at 18–20 days but remain close to nest and roost there for 7–12 days after fledging.
