Molecular Phylogenetics and Evolution, Available online 19 July 2019, In Press, Accepted Manuscript. Highlights• Ultraconserved element (UCE) data resolve the phylogeny of migratory Catharus thrushes.• A fully migratory clade of Catharus thrushes has undergone speciation with gene flow.• Historic gene flow throughout Catharus has produced reticulate gene phylogenies.• Heteropatric speciation has played an important role in the genus.AbstractNew World thrushes in the genus Catharus are small, insectivorous or omnivorous birds that have been used to explore several important questions in avian evolution, including the evolution of seasonal migration and plumage variation. Within Catharus, members of a clade of obligate long-distance migrants (C. fuscescens, C. minimus, and C. bicknelli) have also been used in the development of heteropatric speciation theory, a divergence process in which migratory lineages (which might occur in allopatry or sympatry during portions of their annual cycle) diverge despite low levels of gene flow. However, research on Catharus relationships has thus far been restricted to the use of small genetic datasets, which provide limited resolution of both phylogenetic and demographic histories. We used a large, multi-locus dataset from loci containing ultraconserved elements (UCEs) to study the demographic histories of the migratory C. fuscescens-minimus-bicknelli clade and to resolve the phylogeny of the migratory species of Catharus. Our dataset included more than 2,000 loci and over 1,700 variable genotyped sites, and analyses supported our prediction of divergence with gene flow in the fully migratory clade, with significant gene flow among all three species. Our phylogeny of the genus differs from past work in its placement of C. ustulatus, and further analyses suggest historic gene flow throughout the genus, producing genetically reticulate (or network) phylogenies. This raises questions about trait origins and suggests that seasonal migration and the resulting migratory condition of heteropatry is likely to promote hybridization not only during pairwise divergence and speciation, but also among non-sisters.<a href="https://www.sciencedirect.com/science/article/pii/S1055790319302106" target="_blank">https://www.sciencedirect.com/science/article/pii/S1055790319302106</a>Hylocichla seems to be embedded in Catharus.
