The breeding season varies greatly from region to region. Breeding in China usually occurs from April to June; the breeding period is mostly gregarious, with shallow nests built on trees, bushes or on the ground with branches. The nest is shallow disc-shaped, formed by the intermingling of small branches, the nest is filled with soft dry weeds, according to the 12 nests, the nest diameter is 33.75 cm×18.25 cm, and the nest built in the shrub is 35.45 (20 to 50) cm from the ground. Each clutch lays 2 to 4 eggs, most of which are 4.
The species has a wide distribution range, is not close to the fragile endangered threshold standard for the survival of the species (distribution area or fluctuation range is less than 20,000 square kilometers, habitat quality, population size, distribution area fragmentation), the population trend is stable, so it is evaluated as a species without survival crisis.
