MCC phylogeny of 782 species of the Corvides

This phylogeny was largely based on that from the study Jønsson et al. (2016), which generated a time-calibrated tree using sequence data from 665 species of the Corvides. The remaining 124 species (as recognized by the IOC 2.7) which had no sequence data available at the time of the tree generation were added as polytomies to the maximum clade credibility (MCC) tree of Jønsson et al. (2016) using current taxonomic information. The branch lengths subtending these species were inferred using the polytomy resolution method. Subsequently, we pruned out 7 species for which wing measurements were unavailable.
