We are grateful to A.G. Navarro-Sigüenza (Museo de Zoologı´a, Universidad Nacional Autónoma de México), S. Hackett and D.E. Willard (Field Museum), S. Birks (Burke Museum of Natural History and Culture), and J. Craraft and P. Sweet (American Museum of Natural History), and M.B. Robbins (University of Kansas Natural History Museum) for providing tissue samples under their care. A.G. Navarro-Sigüenza and B. Hernández-Baños made possible sequencing of Cyanocorax dickeyi in Mexico. Two anonymous reviewers made useful comments. This study was funded by grants from the National Science Foundation Dissertation Improvement Grant program (to Bonaccorso; DEB-0508910) and the University of Kansas General Research Fund (to Peterson).

N2 - We studied phylogenetic relationships of the New World Jays (NWJs) based on DNA sequences from three mitochondrial and two nuclear loci. Sampling included at least two individuals from each of the seven NWJ genera and four outgroups of closely related corvids, as well as six of the 16 Cyanocorax species (including two representatives of the previously recognized "Cissilopha"). Phylogenetic analyses were conducted using maximum parsimony, maximum likelihood, and Bayesian analyses for individual genes and a combined dataset. The combined phylogenetic analysis supports the basal position of Cyanolyca to all other NWJs, a (Cyanocorax (Calocitta, Psilorhinus)) clade, and a ((Cyanocitta, Aphelocoma) Gymnorhinus) clade that agrees with a novel morphological synapomorphy uniting Cyanocitta and Aphelocoma. Within Cyanocorax, C. yncas (former "Xanthoura") is basal to a split among former "Cyssilopha" species and the rest of the Cyanocorax species. To explore implications for the historical biogeography of the NJWs, we used Dispersal-Vicariance Analysis, which indicated that NWJs originated either in Mesoamerica or North America + Mesoamerica, with South American NWJs dispersing three times independently from Mesoamerica.
