Abstract

We conducted a biogeographic analysis based on a dense phylogenetic hypothesis for the early branches of corvids, to assess geographic origin of the New World jay (NWJ) clade. We produced a multilocus phylogeny from sequences of three nuclear introns and three mitochondrial genes and included at least one species from each NWJ genus and 29 species representing the rest of the five corvid subfamilies in the analysis. We used the S-DIVA, S-DEC, and BBM analyses implemented in RASP to create biogeographic reconstructions, and BEAST to estimate timing of NWJ diversification. Biogeographic reconstructions indicated that NWJs originated from an ancestor in the Eastern Palearctic or Eastern + Western Palearctic, diversified in Mesoamerica and spread subsequently to North and South America; the group has been diversifying in the New World since the late Miocene.
