Rosellas are small colorful and pretty parrots endemic to Australia ranging in size from 26–37 cm (10–14.5 in) with long tails. Rosellas live in the shrub lands, woodlands, parks and farmlands of Australia and its neighboring small islands. Rosella feed predominantly on seeds and fruit, with food held in the foot. They enjoy bathing in puddles of water in the wild and in captivity. The more colourful rosella species are popular as pet parrots and also as aviary birds. They can live for longer than 20 years, and they are relatively easy to breed. There are 6 brilliant colored species of Rosellas and several subspecies from Australia.

1- Western Rosella – (Platycercus icterotis) – From Southwest Australia 

26 cm (10 in) long, the smallest rosella. The male is mainly red with yellow cheek patches, green rump, and a dark green tail. The female is duller, with a mainly green head, reddish forehead, yellow cheeks, and variegated green-red underparts. Colours of scalloped back feathers differ between two subspecies. The bill is whitish and the irises are dark brown.

2- Crimson Rosella – (Platycercus elegans) from East and Southwest Australia
