From Atlas of Living Australia
The swift parrot (Lathamus discolor), also known as red-faced parrot or red-shouldered parrot breeds in Tasmania and migrates north to south eastern Australia from Griffith-Warialda in New South Wales and west to Adelaide in the winter. It is related to the rosellas, with the feeding habits of a lorikeet. It is the only member in the genus Lathamus.
There were estimated to be fewer than 2000 mature individuals remaining in the wild as of 2011. In 2014, researchers from the Australian National University modelled that the species may face extinction by 2031 due to predation and loss of habitat, the International Union for Conservation of Nature (IUCN) upgraded the status of the swift parrot from endangered to critically endangered in October 2015 based on results from the study. A BirdLife Australia spokesperson said in 2020 that there could be as few as 1,000 left in the wild.
A 2011 genetic study including nuclear and mitochondrial DNA found that the swift parrot was an early offshoot from a lineage giving rise to the genera Prosopeia, Eunymphicus and Cyanoramphus, diverging around 14 million years ago. Its migratory status might have facilitated the spread of its relatives through the Pacific.
The swift parrot is about 25 centimetres (9.8 in) long and has long pointed wings and long tapering tail feathers. It is mainly green with bluish crown and red on the face above and below the beak. The adult female is slightly duller, and the juvenile has a dark brown iris and a pale orange bill. The forehead to throat is crimson and there is also crimson patch at the top, edge of the wing. The female parrots are slightly duller than the males and with a creamy underwing bar. They are noisy, always active and showy, and are very fast with their direct flight. This species is also known as the red-faced or red-shouldered parrot.
The species breeds in Tasmania from September to December. It nests in tree hollows about 6–20 metres from ground level and usually with other breeding pairs. Eggs are white with 3–5 per clutch. Voice is of high pitched tinking chattering, piping pee-pit, pee-pit. They only breed from September to March.
The swift parrot migrates across Bass Strait between Tasmania and the mainland of Australia. They arrive in Tasmania during September and return to south-eastern Australia during March and April. They can be found as far north as south-eastern Queensland and as far west as Adelaide in South Australia, although recent sightings have been restricted to the south-eastern part of the state.

The presence of the winter-flowering golden wattle (Acacia pycnantha) is positively correlated with numbers of swift parrots overwintering in box–ironbark forest in central Victoria, while the presence of flowering eucalypts has no correlation.
It is thought that only 1000 pairs remain in the wild. Habitat destruction and loss of old trees with nesting hollows are critical factors in its decline. Sugar gliders are the major predator of nesting parrots in mainland Tasmania, accounting for 85% of kills, but are absent from Bruny and Maria Islands.
Swift parrots are listed as endangered on the Australian Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), which has been criticised for failing to protect them and other threatened species.
