Regent parrot

Polytelis anthopeplus

The Regent Parrot is a slim parrot with a long, dusky tapering tail and back-swept wings. It is mostly yellow, with blue-black wings and tail. There is a prominent yellow shoulder patch and red patches in the wings, which show up against the dark wings in flight. The bill is deep red or pink. Females and juveniles are duller olive-green with pinkish, duller wing patches.

They are only found in Australia and there are  two separate populations separated by the Nullarbor Plain: one in the Mallee regions of eastern Australia, wherer they may be observed in River Red Gum, Eucalyptus camaldulensis, floodplain, woodland and mallee.

The other in the Wheatbelt region of southern Western Australia in open forest and woodland, especially Salmon Gum, E. salmonophloia..

They forage in pairs or small flocks, usually on the ground feeding on seeds of grasses,plants and cereal crops, especially wheat, even spilled grain on the ground. They also eat buds and flowers, insect larvae, psyllids and lerps in the canopy of trees..

Though the populations are widely separated, the birds of each region do not appear especially different, one being a little duller than the other. There are, however, other differences between the two populations, especially in how they have fared: eastern populations are endangered, while the western population is thought to be increasing.

As other parrots the Regent Parrot nest is the hollow trunk of a tall tree.
