Swift parrot

The swift parrot (Lathamus discolor) 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 was 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. The surgeon John White described the swift parrot in 1790 as the red-shouldered paroquet (Psittacus discolor). It was placed in the genus Lathamus by René Primevère Lesson in 1830. The swift parrot is only distantly related to the blue-winged and orange-bellied parrots, suggesting that two separate lineages might have become migratory. 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 cm (10 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 parrots/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.
