Hylocitreidae – Yellow-flanked Whistler
Hylocitredidae are represented by just one hylocitrea; Hylocitrea bonensis, also known as the Yellow-flanked Whistler or Olive-flanked Whistler, is a species of bird that is endemic to montane forests on the Indonesian island of Sulawesi. It is monotypic within the genus Hylocitrea, and has traditionally been considered a member of the family Pachycephalidae, but recent genetic evidence suggests it should be placed in a monotypic subfamily of the family Bombycillidae, or even its own family, Hylocitreidae.
DNA sequencing suggesting that it is not related to other whistlers and is actually closer to the Waxwings but never-the-less, forms a family all by itself; it is endemic to montane forests of Sulawesi:
