Taxonomy and Systematics
The placement of this species and genus within the passerines is uncertain. It has been suggested that it belongs with the whistlers, in the Pachycephalidae family, based on its bright yellow plumage and voice, and the species is sometimes known as the Dwarf Whistler. Others have suggested placing it with the Australasian robins in the family Petroicidae, but the nest architecture is unlike that of the family; in fact its nests more closely resemble those of the thornbills in the family Acanthizidae, another family to which it has sometimes been aligned. This relationship was supported by a 2009 molecular study which placed the species in that family. There are four subspecies.
