To elucidate the relationships and spatial range evolution across the world of the bird genus Turdus (Aves), we produced a large genomic dataset comprising ca. 2 million nucleotides for ca. 100 samples representing 53 species, including over 2,000 loci. Our large multilocus dataset, combined with dense species-level sampling and analyzed under probabilistic methods, brings important insights into historical biogeography and systematics, even in a scenario of fast and spatially complex diversification.
