dc.description.abstractNew World orioles (Icterus) include several closely related species and subspecies pairs that provide excellent opportunities for studying recent speciation. We examined a subspecies pair in the Orchard Oriole group: Orchard Oriole (I. spurius spurius), a longdistance migrant that breeds in eastern North America, and Fuertes’s Oriole (I. s. fuertesi), a short-distance migrant that breeds in a restricted range in Veracruz, Mexico. We sequenced parts of the mitochondrial cytochrome-b gene (925 base pairs) and control region (344 base pairs) from 23 Orchard Orioles and 7 Fuertes’s Orioles. Subspecies are not reciprocally monophyletic. Instead, our data suggest that at least one taxon is paraphyletic or polyphyletic. We found little support for any further phylogenetic structure, including whether one subspecies might be derived from the other. However, haplotype frequency analysis suggests that there is little or no current gene fl ow between the taxa. The phylogenetic relationship between Orchard and Fuertes’s orioles is likely a result of recent divergence and incomplete lineage sorting. That interpretation is consistent with theoretical models of speciation, which predict patterns of nonmonophyly at early stages of taxon divergence. Our findings suggest that Orchard and Fuertes’s orioles are separate species and provide a case study for evaluating the importance of monophyly in defi ning species limits.en_US
