Eastern Rosella
The Eastern Rosella (Platycercus eximius) is a rosella native to southeast of the Australian continent and to Tasmania. It has been introduced to New Zealand where feral populations are found in the North Island (notably in the northern half of the island and in the Hutt Valley) and in the hills around Dunedin in the South Island.

Taxonomy
The Eastern Rosella was named by George Shaw in 1792. It is sometimes considered a subspecies of the Pale-headed Rosella (P. adscitus). The term White-cheeked Rosella has been used for a species or superspecies combining the Pale-headed and Eastern forms. Hybrids of the two taxa have been recorded where their ranges meet in northeastern New South Wales and southeastern Queensland.
Three subspecies of Eastern Rosella are recognised:
Three subspecies of Eastern Rosella are recognised:
- P. e. eximius, Victoria and southern New South Wales. Black feathers on the back have green margins. Rump is pale green.

- P. e. diemenensis, eastern Tasmania. White cheek patches are larger and the red on the head is darker.
