. The nesting in Xiaoxingan region is mainly in May and June. They breed mainly in low valleys at the base of hills. The home range of a pair can be about 2000-5000 sq. m. The nest is built in about three to four days by the female alone. The clutch is 4-7 eggs which are incubated by the female alone for about 11–12 days. The adults forage within about of the nest to feed the chicks. The young fledge after 14–15 days. It was first noted to winter in central India in 1989, it has since been found to winter in southwestern India and Sri Lanka.
