Figure 3. Time-scaled maximum clade credibility tree based on a partial sequence of flamingos cytochrome b (611 bp). The analysis includes the six extant flamingo species; individuals from the Caribbean flamingo (Phoenicopterus ruber) are identified by their colony of origin: CU (Cuba), Bon (Bonaire) and Gal (Galápagos). Blue bars represent the 95% highest posterior density intervals (95% HPD) of the node ages (in millions of years). The crown Phoenicopteridae diversified around 13 (9–18; 95% HPD) Mya followed by the split of the two main extant flamingo clades approximately 7 Mya. The expansion of existing haplotypes of all species occurred in the last two million years. The branch leading to the endemic haplotype from Galápagos, sample 51637, is coloured red.
