Abstract
SIBLEY, C. G. and J. E. AHLQUIST. 1982. The relationships of the Australo-Papuan sittellas Daphoenositta as indicated by DNA-DNA hybridization. Emu 82: 173–176. The taxonomic relationships of Daphoenositta were examined by comparing the single-copy DNA sequences of radio-iodine (1251) labelled DNA of the Varied Sittella D. chrysoptera with the DNAs of thirty-eight other species, representing thirty-five genera, of oscine passerine birds (Passeres). Of the taxa examined, Daphoenositta was found to be most closely related to Pachycephala, Pitohui, Colluricincla, Monarcha, and other members of a large, primarily Australo-Papuan, assemblage which also includes such morphologically diverse taxa as the birds of paradise, crows, drongos, quail-thrushes, cuckoo-shrikes, fantails, scrub-robins Drymodes, lyrebirds, scrub-birds, and bower-birds. There is no convincing evidence that the sittellas are closely related to the nuthatches Sitta, the Holarctic creepers Certhia, the Philippine creepers Rhabdornis, the Afro-Asian creeper Salpornis, the Australo-Papuan tree creepers Climacteris, the Eurasian Wallcreeper Tichodroma, or the Coral-billed Nuthatch Hypositta of Madagascar. Some Australo-Papuan taxa that are members of a separate major assemblage are Malurus, Sericomis, Acanthiza, the honeyeaters Meliphagidae, and the Australian chats Ephthianura.This publication has 8 references indexed in Scilit:
