Studies the causes and consequences of speciation in birds, summarized in the book Speciation In Birds (2008). Investigates the origin of differences between species by studying geographical variation in songs, plumages, and ecological attributes, asking how these differences contribute to speciation. Studied a ring species-two species that are connected by a series of intergrading populations around a geographical barrier-demonstrating a key role of song divergence in the origin of reproductive isolation and the role of gene flow, as assessed using genomic methods. Provided comprehensive understanding of speciation in a continental group, and how these patterns differ from islands. Works extensively on phylogenetic analyses of species build up along diversity gradients (such as the latitudinal gradient). Recent work has analyzed the evolution of color and color vision in birds.
