The display consist of continual singing by male to female, contact calls, wing-shivering by male with wings drooped, tail fanned close to female, and courtship-feeding of female by male. The nest-site is selected by female, male singing nearby. The nest is built by female, mostly from moss, grass stems, old leaves and animal hair, placed on ground under rock, fallen tree or tree roots, crevice in bank or old wall, usually beneath tall vegetation or low scrub or in hole in tree; same territory frequently occupied in successive years. They lay a clutch of 3-7eggs. The incubation is done by both sexes, either equally or with female doing more of the work for a period of 12–13 days. The fledging period is 11-15days. The youngare fed by both parents. The young become independent after a further 21 days.
