The Eastern Rosella (Platycercus eximius) is a rosella native to southeast of the Australian continent and to Tasmania. Eastern Rosellas are medium-sized colourful parrots with distinctive white cheek patches. It has a red head, neck and breast, with yellowish to greenish upper parts, a yellow underbody and a yellow-green to blue-green rump, with a red undertail. The shoulders are bright blue. Females are usually similar to males, but sometimes duller and young birds are even duller and can be aged by their bill colour, which is yellow or orange, changing to off-white when mature.
