Generally, the Crested Jay (Platylophus galericulatus) is put here, however clearly this is not right, as recommended by anatomical and sub-atomic confirmation. Its position stays uncertain; it doesn't appear to be a corvid whatsoever. As per Ericson et al. (2005), jays are not a monophyletic gathering. Rather, they can be isolated into an American and an Old World ancestry (the last including the ground jays and the Piapiac), while the ash jays of the class Perisoreus structure a gathering of their own. The Black Magpie, once in the past accepted to be identified with jays, is delegated a treepie.
