Excerpt from A Comparative Study of the Egg-White Proteins of Passerine Birds The Starch-gel electrophoretic patterns of the egg-white proteins of 668 species of the avian order Passeriformes were studied. Evidence of family level systematic relationships was sought and compared with evidence from anatomy, behavior, etc. In many cases the previously accepted classification was supported, in others questions were raised by the protein data. These include: (1) The New World non-oscine families seem to be more closely related ...

Excerpt from A Comparative Study of the Egg-White Proteins of Passerine Birds The Starch-gel electrophoretic patterns of the egg-white proteins of 668 species of the avian order Passeriformes were studied. Evidence of family level systematic relationships was sought and compared with evidence from anatomy, behavior, etc. In many cases the previously accepted classification was supported, in others questions were raised by the protein data. These include: (1) The New World non-oscine families seem to be more closely related to one another than any one of them is to the Pittidae, Acanthisittidae or other Old World non-oscine families. (2) The Corvidae and Laniidae may be related. (3) The Paradiseidae are probably related to the Cracticidae. (4) Chamaea is probably closest to the Sylviidae, not to the Timaliidae. (5) Psaltriparus and Aegithalos are closely related to one another and may be closer to the sylviids than to Parus. (6) The Timaliidae may be a natural group including Picathartes but not including either Panurus or Chamaea. (7) The Sylviidae and Muscicapidae are closely related to one another but are less closely related to the Turdidae. (8) Prunella is closer to the sylviid-muscicapid assemblage than to the thrushes. (9) Zeledonia is a nine-primaried oscine, probably best placed with the paruline warblers, not in the Turdidae. (10) The Nectariniidae and Meliphagidae differ markedly and probably are not closely related. (11) The ploceines and estrildines are related to one another. (12) Passer is unlike the ploceids and may be closer to the fringillids. (13) Vidua has an egg-white pattern like that of Passer and differs from the ploceids in this and other characters. (14) Fringilla is closely related to the carduelines as proved by the existence of valid, cage-bred, hybrids. (15) The carduelines are most closely related to the other nine-primaried oscines, not to the estrildines. (16) The Drepaninines were probably derived from a cardue line ancestor.
