Estimated tree using data from Schweizer et al., (2014)

Our estimated tree generated using data from Schweizer et al., (2014). The tree is based on three partial nuclear genes (c-mos, RAG-1 and Zenk) and one mitochondrial gene (ND2) for 78 parrot species within the order Psittaciformes and one outgroup, Falco tinnunculus. The accession numbers were taken from the supplementary material of Schweizer et al., (2014). The tree was estimated using BEAST v2.1.3 (Bouckaert et al., 2014) on the constrained topology from Schweizer et al., (2014). We used a HKY + Γ model of nucleotide evolution with separate partitions for each gene, a relaxed log-normal clock, and a coalescent prior. Further information and full references can be found in the supplementary material of our paper.
