Abstract:The Poo-uli (Melamprosops phaeosoma), discovered on Maui in 1973, was originally believed to be a Hawaiian honeycreeper (Drepanidinae). Doubts as to the validity of this classification prompted an investigation of the defining characters of the subfamily and the possible position of M. phaeosoma within it. The Drepanidinae are monophyletic with a suite of certain and possible synapomorphies that cluster the group, but Melamprosops lacks all of these characters. Hawaiian honeycreepers have a distinctive odor which the Poo-uli lacks. Its tongue has prominent rearward projections whereas drepanidine tongues lack "lingual wings." Most drepanidines lack the usual passerine predator-response behaviors but M. phaeosoma exhibits them. Vocalizations of the Poo-uli do not resemble those of any of the three vocal groupings of Hawaiian honeycreepers. The color pattern of M. phaeosoma is unique among native Hawaiian birds. Phenotypic characters thus provide no basis for inclusion of Melamprosops in the Drepanidinae; its relationships are unknown.
