Order: Passeriformes. Family: Drepanididae
Hawaiian honeycreepers are small passerine birds endemic to Hawaiʻi. Most authorities categorize this group as a family Drepanididae, but some biologists still place as a subfamily Drepanidinae of the finch family Fringillidae. The wide range of bills in this group, from thick finch-like bills to slender downcurved bills for probing flowers have arisen through adaptive radiation, where an ancestral finch has evolved to fill a large number of ecological niches.
