For birds, timing is one of the key factors that limit their migration activities. The different physical characteristics in both sexes and the different molting patterns in both ages may lead to the great differences in timing of autumn migration. In October and November of 2021 and 2022, 643 thrushes were banded in Mingxi County. A total of seven species were banded, including Eyebrowed Thrush (Turdus obscurus) (364), Grey-backed Thrush (T. hortulorum) (161), Japanese Thrush (T. cardis) (79), White's Thrush (Zoothera aurea) (15), Pale Thrush (T. pallidus) (20), Siberian Thrush (Geokichla sibirica) (3) and Dusky Thrush (T. eunomus) (1). The intraspecific and interspecific differences in timing of migration and biometric characteristics among three dominant species were compared. Their migration dynamics, wing length and fat score distribution were analyzed. The arrival time of adults in Eyebrowed Thrush was, significantly, 2 days earlier than that of immatures, and adult Japanese Thrushes arrived 3 days earlier than immatures. No significant differences in arrival time were found between sexes for the three species. The arrival time of Eyebrowed Thrush was, significantly, 3 days later than that of Grey-backed Thrush and 2 days later than that of Japanese Thrush. The wing length of adults was significantly longer than that of immatures in Eyebrowed Thrush, while there was no significant difference both in Grey-backed Thrush and Japanese Thrush, indicated that having longer wings may explain why the adults arrive before the immatures. The wing pointedness index of Eyebrowed Thrushes and the Grey-backed Thrushes decreased significantly with the arrival time, while fat content increased significantly with the arrival time, indicating that the individuals with longer migration distance arrived earlier and carried less fat. The migration peaks of the three species were less than 10 days, and the average fat score were less than 2, indicating that the three species adopted a strategy to minimize total energy expenditure during migration, passing through Mingxi in a relatively short time. As an important stopover sites for thrushes, the ecological environment in Mingxi County should be better protected to provide high quality habitat. Human disturbance should be reduced as much as possible during the migration peak, so as not to affect the resting activities of thrushes.
