Hawaiian Honeycreeper Phylogeny
The Poouli (Melamprosops phaeosoma) was discovered in 1973 by a group or students from the University of Hawaii. Its membership in the Hawaiian honeycreeper clade was (until recently) controversial, mainly because its appearance and behavior are so different from other living honeycreepers. Its particularly lacked the “old tent” odor characteristic of other honeycreepers.
In 2011, Heather Lerner and her colleagues deciphered phylogeny of the 19 Hawaiian honeycreepers that were not yet officially declared to be extinct at the time, including the Poouli. The researchers sequenced mitochondrial and nuclear DNA samples taken from the honeycreepers, and also from 28 other birds (outgroups). Phylogenetic analysis of these data firmly establishes the Poouli as a member of the clade, and also reveals the Eurasian rosefinch as the clade’s closest relative (FIGURE 18.11).
FIGURE 18.11 Hawaiian honeycreeper phylogeny. This cladogram was constructed using sequence comparisons of mitochondrial DNA (whole genome), and 13 nuclear DNA loci of 19 Hawaiian honeycreeper and 28 other finch species.
