The eastern rosella (Platycercus eximius) is a rosella native to southeastern Australia and 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, Taranaki, Waikato and in the Hutt Valley) and in the hills around Dunedin in the South Island.
The eastern rosella is 30 cm (12 in) long. It has a red head and white cheeks. The beak is white and the irises are brown. The upper breast is red and the lower breast is yellow fading to pale green over the abdomen. The feathers of the back and shoulders are black, and have yellowish or greenish margins giving rise to a scalloped appearance that varies slightly between the subspecies and the sexes. The wings and lateral tail feathers are bluish while the tail is dark green. The legs are grey. The female is similar to the male though duller in colouration and has an underwing stripe, which is not present in the adult male. Juveniles are duller than females and have an underwing stripe. The diet of eastern rosellas mainly consists of fruit, seeds, flowers and insects.
