Rosellas are in a genus that consists of six species and nineteen subspecies. These colourful parrots from Australia are in the genus Platycercus. Platycercus means "broad-tailed" or "flat-tailed", reflecting a feature common to the rosellas and other members of the broad-tailed parrot tribe. Their diet is mainly seeds and fruit.
There are, broadly speaking, three groups of rosella species. They are the blue-cheeked species which includes elegans and caledonicus, the white-cheeked species, eximius, adscitus and venustus and the yellow-cheeked species, icterotis.
Western rosellas are a popular bird in aviaries and for zoological gardens, displaying the favourable characteristics of related species without the reputation for aggression and raucous vocalisation. Their status in Australian aviculture is classified as secure.
