During the breeding period, it mainly inhabits montane coniferous forests, birch forests, mixed coniferous and broad-leaved forests and sparse forest shrublands on the upper part of the mountain at an altitude of more than 1000 meters, especially under wet fir and yue birch forests. Migration seasons and winters are also found in secondary forests in low hills and foothill plains, in sparse forests at the edge of forests, by roadsides and streams, and sometimes even in sparse forests, shrublands and grass slopes near orchards and villages. It is often seen alone or in pairs, sometimes in small groups of 3-5 birds, especially in autumn. Mainly ground-dwelling, mostly running on the ground under the forest or jumping between the low branches of the shrub, the sex is very hidden, in addition to the male birds standing on the branches during the breeding period, generally in the understory shrubs between the activities and foraging. Stops often swing up and down. The red-winged blue-tailed plover breeds in China and overwinters in China, and is both a summer and winter migratory bird.
The nest is shared by male and female parent birds, but the female is the main bird, and the male still sings among the trees in the nest area from time to time, and occasionally participates in the nest activities. Each nesting time takes 7-10 days. The nest is cup-shaped, consisting mainly of moss, and the inner surface is sometimes covered with animal hair and pine needles. The size of the nest is 13.5-15.0 cm outer diameter, 7.0-7.5 cm inner diameter, and 3-4 cm deep. Eggs are laid as soon as the nest is built, and some rest for a few days before laying eggs. Breed 1 litter per year, lay 1 egg per day, and lay a second egg at 1 interval. Each clutch usually lays 4-7 eggs, mostly 5-6. Egg white
