Haplotype networks for the three nuclear genes (Bfib5, Rag1 and CHDZ) and the combined genes for Coereba flaveola. Branch lengths are proportional to the number of mutations and the size of each node is proportional to haplotype frequency. Each of the clades defined from the mitochondrial or nuclear consensus trees (Figures 2 and 3) is given a specific color.
