Australaves[3] is a recently defined[4]clade of birds, consisting of the Eufalconimorphae (passerines, parrots and falcons) as well as the Cariamiformes (including seriemas and the extinct "terror birds").[5] They appear to be the sister group of Afroaves.[5] As in the case of Afroaves, the most basal clades have predatory extant members, suggesting this was the ancestral lifestyle;[6] however, some researchers like Darren Naish are skeptical of this assessment, since some extinct representatives such as the herbivorous Strigogyps led other lifestyles.[7] Basal parrots and falcons are at any rate vaguely crow-like and probably omnivorous.[8]
