Psephotus

Psephotus haematonotus is a small-sized parrot with an attenuated tail, and it occurs broadly in southeastern Australia from the Lake Eyre Basin deep in the continent’s interior south and east to the coasts. It diverged at 11.1 Mya (5.2– 15.3; fig. 11). Its sexual dimorphism generally recalls that of Clarkona in that males are extensively green and females are grayish olive, but details of plumage patterning differ profoundly. Psephotus haematonotus has unique, whistled vocalizations. Although previously thought to be the eastern member of a vicariant sister pair with Clarkona varia (e.g., Ford, 1974) clarification of their phylogenetic positions dispelled this.
