The Crimson Rosella lives in southeast and east Australia; the nominate subspecies in the southeast and two darker subspecies (nigrescens and melanoptera) on the east coast and Kangaroo Island.
The beautiful, brightly-coloured Rosellas are related to the grass parakeets and often spend time on the ground.
The darker-winged subspecies?

Platycercus elegans flaveolus
The Yellow Rosella from southeast Australia, also called the Murray Rosella, was thought to be a separate species of Rosella, but is now considered a subspecies of the Crimson.
It resembles the Green Rosella from Tasmania but is slightly smaller, has a yellower front and rump, and the feathers on its back are black with light yellow edging.
Platycercus elegans adelaidae/subadelaidae
The Adelaide Rosella was thought to be a separate species of Rosella, then a subspecies of the Crimson Rosella and, with further DNA testing, is now considered a race of hybrids
of the Crimson Rosella and the Yellow Rosella, itself also previously considered a separate species but now considered a subspecies of the Crimson.
Many Adelaides show more red on their front than those shown here.
This rosella looks similar to the Crimson but is clearly not a blue-cheeked species. A possible hybrid between Crimson and the white-cheeked Eastern.
Said to be "Golden-mantled" subspecies "ceciliae," with comment it was not pure-bred. Clearly not a white-cheeked Eastern;
would seem to have Crimson ancestry.
