This Australo-Papuan family has a single endemic species, the Varied Sittella Daphoenositta chrysoptera, which contains five very different looking subspecies, the Orange-winged Sittella D. c. chrysoptera, the White-headed Sittella D. c. leucocephala, the White-winged Sittella D. c. leucoptera, the Black-capped Sittella D. c. pileata and the Striated Sittella D. c. striata. All are small and arboreal, prying under loose bark and within crevices with a thin, slightly upcurved bill.
