Integrative taxonomy of two thrush complexes (Aves: Turdidae) reveals introgression across sister species

The classification of some Turdus species, such as the Naumann’s and dusky thrush complexes and the red-throated and black-throated thrush complexes, is controversial. Herein, we used molecular data and morphological characters to review the taxonomy of these thrush complexes and analyze the genetic differentiation between them. Herein, we examined the genetic characteristics of 13 microsatellite loci in all individuals and total of 129 alleles were detected. In parallel, we have a further judgment on their classification status by measuring 5 morphological features (tail length, wing length, toe length, claw length and instep length).
