The evolution of migration in birds has fascinated biologists for centuries. In this study, we performed phylogenetic‐based analyses of Catharus thrushes, a model genus in the study of avian migration, and their close relatives. For these analyses, we used both mitochondrial and nuclear genes, and the resulting phylogenies were used to trace migratory traits and biogeographic patterns. Our results...
Seasonal migration of Nearctic‐Neotropical passerine birds may have profound effects on the diversity and abundance of their host‐associated microbiota. Migratory birds experience seasonal change in environments and diets throughout the course of the annual cycle that, along with recurrent biological events such as reproduction, may significantly impact their microbiota. In this study, we characterize...
