Résumé :	Phylogenetic relationships among Neotropical honeycreepers were studied by using cytochrome b sequence data. Although honeycreepers were once placed in their own family (Coerebidae), these species did not form a monophyletic group in any of the phylogenies in this study. Thus, our results indicate that nectar-feeding evolved independently multiple times among these birds. The Neotropical honeycreepers are best considered disparate members of a larger radiation of tanagers and finches, in which bill size and shape, and associated feeding behaviors have changed frequently to fill a variety of niches. Our phylogenies also provide specific taxonomic recommendations on the placement of each honeycreeper genus. The use of the taxon Coerebidae is no longer warranted given the well-supported relationships between different honeyereeper species and a variety of tanagers and finches.
