Relationships and ages of the flamingos. Cladogram showing the relationships of the living flamingos. The flamingos fall out in two sub-clades with high support, congruent with the topology recovered by Sibley and Ahlquist . Genus Phoenicoparrus has been expanded to include all members of the deep-keeled clade (see Discussion). Posterior probabilities (Bayesian inference) and bootstrap support values (maximum likelihood) are shown above each node. Numbers and letters to the right of each node indicate individual genes and data subsets which recover that monophyletic clade. Key: 1, RHEB1; 2, TIMM17A; 3, TCF3; 4, RPS24; 5, SLC29A4; 6, NFKBIZ; 7, G3PDH; 8, myoglobin; 9, ZENK; 10, ZENK 3’UTR; 11, COI; 12, cyt b; n, nDNA subset; mt, mtDNA subset. RHEB1 failed to recover sister status between the American and Greater Flamingos in a maximum likelihood framework with high support, denoted by ‘1*’.
