Adelaide Rosella

Rosella

[roh-zel-uh]

A rosella is one of 5-8 species of colorful Australian parrots in the genus Platycercus. Platycercus means "broad-" or "flat-tailed", reflecting a feature common to the rosellas and other members of the broad-tailed parrot tribe. Their diet consists mainly of seeds and fruit.

Habitat

Rosellas are native to Australia and some nearby islands, where they inhabit forests, woodlands, farmlands, and suburban parks and gardens. They are confined to the coastal mountains and plains and are absent from the outback. Introduced populations have also established themselves in New Zealand and Norfolk Island.

Description

Rosellas range in size from 25–30 cm (10–12 in). The feathers on their backs show an obvious scalloping appearance with colouring that differs with the species.

Etymology

A story goes that early European settlers first encountered the Eastern Rosella at Rose Hill, now a Sydney suburb, and so they called it the Rosehill Parakeet, which became, "Rosehiller", which eventually "Rosella". However, there is also a second story that the name is derived from 'Rosetta', the first name of the wife of George Fife Angas, a settler in Australia, but he forgot to cross his T's (leaving them appearing as lowercase L's), hence "rosella".

Aviculture

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.
