The final clade here should be Metornithes (=={_Mononykus_ +
Neornithes}) or Pygostylia (=={_Confucisuornis_ + Neornithes}), not Aves
(=={_Archaeopteryx_ + Neornithes}).

The recent trend (at least among some dino researchers, particularly at the AMNH) is to call this clade "Avialae" ={_Archaeopteryx_ + Neornithes}. "Aves", however, is limited to the crown-group of modern birds. Personally I prefer Aves = {_Archaeopteryx_ + Neornithes}.
