It usually remains in the same area throughout the year, though some birds descend from higher altitudes to spend autumn and winter in lowland areas, and return to the hills in spring.
The female usually builds the nest, though sometimes she is assisted by the male. The nest is a shallow bowl made of twigs, grass and bark, bound together with spider web and lined with fine grass. The female usually lays two or three eggs which are incubated by both parents for up to 17 days. The young birds remain in the nest for up to 13 days, and both parents feed and brood the young. They breed one brood a year.
