Platycercus venustus (Northern rosella)

Synonyms: Platycerus venustus

Wikipedia Abstract

The northern rosella (Platycercus venustus), also known as Brown's parakeet or smutty rosella, is found in Australia's Top End. It is found in open savannah country throughout the Gulf of Carpentaria and Arnhem Land to the Kimberley. This species is unusually coloured for a rosella, with a dark crown and white cheeks similar to its pale-headed rosella and the eastern rosella relatives. It was first described by German naturalist Heinrich Kuhl. The specific epithet is derived from the Latin venustus "charming, lovely or graceful".
